1.1 The Science of Biology

Learning objectives.

By the end of this section, you will be able to do the following:

• Identify the shared characteristics of the natural sciences
• Summarize the steps of the scientific method
• Compare inductive reasoning with deductive reasoning
• Describe the goals of basic science and applied science

What is biology? In simple terms, biology is the study of life. This is a very broad definition because the scope of biology is vast. Biologists may study anything from the microscopic or submicroscopic view of a cell to ecosystems and the whole living planet ( Figure 1.2 ). Listening to the daily news, you will quickly realize how many aspects of biology we discuss every day. For example, recent news topics include Escherichia coli ( Figure 1.3 ) outbreaks in spinach and Salmonella contamination in peanut butter. Other subjects include efforts toward finding a cure for AIDS, Alzheimer’s disease, and cancer. On a global scale, many researchers are committed to finding ways to protect the planet, solve environmental issues, and reduce the effects of climate change. All of these diverse endeavors are related to different facets of the discipline of biology.

The Process of Science

Biology is a science, but what exactly is science? What does the study of biology share with other scientific disciplines? We can define science (from the Latin scientia , meaning “knowledge”) as knowledge that covers general truths or the operation of general laws, especially when acquired and tested by the scientific method. It becomes clear from this definition that applying scientific method plays a major role in science. The scientific method is a method of research with defined steps that include experiments and careful observation.

We will examine scientific method steps in detail later, but one of the most important aspects of this method is the testing of hypotheses by means of repeatable experiments. A hypothesis is a suggested explanation for an event, which one can test. Although using the scientific method is inherent to science, it is inadequate in determining what science is. This is because it is relatively easy to apply the scientific method to disciplines such as physics and chemistry, but when it comes to disciplines like archaeology, psychology, and geology, the scientific method becomes less applicable as repeating experiments becomes more difficult.

These areas of study are still sciences, however. Consider archaeology—even though one cannot perform repeatable experiments, hypotheses may still be supported. For instance, archaeologists can hypothesize that an ancient culture existed based on finding a piece of pottery. They could make further hypotheses about various characteristics of this culture, which could be correct or false through continued support or contradictions from other findings. A hypothesis may become a verified theory. A theory is a tested and confirmed explanation for observations or phenomena. Therefore, we may be better off to define science as fields of study that attempt to comprehend the nature of the universe.

Natural Sciences

What would you expect to see in a museum of natural sciences? Frogs? Plants? Dinosaur skeletons? Exhibits about how the brain functions? A planetarium? Gems and minerals? Maybe all of the above? Science includes such diverse fields as astronomy, biology, computer sciences, geology, logic, physics, chemistry, and mathematics ( Figure 1.4 ). However, scientists consider those fields of science related to the physical world and its phenomena and processes natural sciences . Thus, a museum of natural sciences might contain any of the items listed above.

There is no complete agreement when it comes to defining what the natural sciences include, however. For some experts, the natural sciences are astronomy, biology, chemistry, earth science, and physics. Other scholars choose to divide natural sciences into life sciences , which study living things and include biology, and physical sciences , which study nonliving matter and include astronomy, geology, physics, and chemistry. Some disciplines such as biophysics and biochemistry build on both life and physical sciences and are interdisciplinary. Some refer to natural sciences as “hard science” because they rely on the use of quantitative data. Social sciences that study society and human behavior are more likely to use qualitative assessments to drive investigations and findings.

Not surprisingly, the natural science of biology has many branches or subdisciplines. Cell biologists study cell structure and function, while biologists who study anatomy investigate the structure of an entire organism. Those biologists studying physiology, however, focus on the internal functioning of an organism. Some areas of biology focus on only particular types of living things. For example, botanists explore plants, while zoologists specialize in animals.

Scientific Reasoning

One thing is common to all forms of science: an ultimate goal “to know.” Curiosity and inquiry are the driving forces for the development of science. Scientists seek to understand the world and the way it operates. To do this, they use two methods of logical thinking: inductive reasoning and deductive reasoning.

Inductive reasoning is a form of logical thinking that uses related observations to arrive at a general conclusion. This type of reasoning is common in descriptive science. A life scientist such as a biologist makes observations and records them. These data can be qualitative or quantitative, and one can supplement the raw data with drawings, pictures, photos, or videos. From many observations, the scientist can infer conclusions (inductions) based on evidence. Inductive reasoning involves formulating generalizations inferred from careful observation and analyzing a large amount of data. Brain studies provide an example. In this type of research, scientists observe many live brains while people are engaged in a specific activity, such as viewing images of food. The scientist then predicts the part of the brain that “lights up” during this activity to be the part controlling the response to the selected stimulus, in this case, images of food. Excess absorption of radioactive sugar derivatives by active areas of the brain causes the various areas to "light up". Scientists use a scanner to observe the resultant increase in radioactivity. Then, researchers can stimulate that part of the brain to see if similar responses result.

Deductive reasoning or deduction is the type of logic used in hypothesis-based science. In deductive reasoning, the pattern of thinking moves in the opposite direction as compared to inductive reasoning. Deductive reasoning is a form of logical thinking that uses a general principle or law to predict specific results. From those general principles, a scientist can deduce and predict the specific results that would be valid as long as the general principles are valid. Studies in climate change can illustrate this type of reasoning. For example, scientists may predict that if the climate becomes warmer in a particular region, then the distribution of plants and animals should change.

Both types of logical thinking are related to the two main pathways of scientific study: descriptive science and hypothesis-based science. Descriptive (or discovery) science , which is usually inductive, aims to observe, explore, and discover, while hypothesis-based science , which is usually deductive, begins with a specific question or problem and a potential answer or solution that one can test. The boundary between these two forms of study is often blurred, and most scientific endeavors combine both approaches. The fuzzy boundary becomes apparent when thinking about how easily observation can lead to specific questions. For example, a gentleman in the 1940s observed that the burr seeds that stuck to his clothes and his dog’s fur had a tiny hook structure. On closer inspection, he discovered that the burrs’ gripping device was more reliable than a zipper. He eventually experimented to find the best material that acted similarly, and produced the hook-and-loop fastener popularly known today as Velcro. Descriptive science and hypothesis-based science are in continuous dialogue.

The Scientific Method

Biologists study the living world by posing questions about it and seeking science-based responses. Known as scientific method, this approach is common to other sciences as well. The scientific method was used even in ancient times, but England’s Sir Francis Bacon (1561–1626) first documented it ( Figure 1.5 ). He set up inductive methods for scientific inquiry. The scientific method is not used only by biologists; researchers from almost all fields of study can apply it as a logical, rational problem-solving method.

The scientific process typically starts with an observation (often a problem to solve) that leads to a question. Let’s think about a simple problem that starts with an observation and apply the scientific method to solve the problem. One Monday morning, a student arrives at class and quickly discovers that the classroom is too warm. That is an observation that also describes a problem: the classroom is too warm. The student then asks a question: “Why is the classroom so warm?”

Proposing a Hypothesis

Recall that a hypothesis is a suggested explanation that one can test. To solve a problem, one can propose several hypotheses. For example, one hypothesis might be, “The classroom is warm because no one turned on the air conditioning.” However, there could be other responses to the question, and therefore one may propose other hypotheses. A second hypothesis might be, “The classroom is warm because there is a power failure, and so the air conditioning doesn’t work.”

Once one has selected a hypothesis, the student can make a prediction. A prediction is similar to a hypothesis but it typically has the format “If . . . then . . . .” For example, the prediction for the first hypothesis might be, “ If the student turns on the air conditioning, then the classroom will no longer be too warm.”

Testing a Hypothesis

A valid hypothesis must be testable. It should also be falsifiable , meaning that experimental results can disprove it. Importantly, science does not claim to “prove” anything because scientific understandings are always subject to modification with further information. This step—openness to disproving ideas—is what distinguishes sciences from non-sciences. The presence of the supernatural, for instance, is neither testable nor falsifiable. To test a hypothesis, a researcher will conduct one or more experiments designed to eliminate one or more of the hypotheses. Each experiment will have one or more variables and one or more controls. A variable is any part of the experiment that can vary or change during the experiment. The control group contains every feature of the experimental group except it is not given the manipulation that the researcher hypothesizes. Therefore, if the experimental group's results differ from the control group, the difference must be due to the hypothesized manipulation, rather than some outside factor. Look for the variables and controls in the examples that follow. To test the first hypothesis, the student would find out if the air conditioning is on. If the air conditioning is turned on but does not work, there should be another reason, and the student should reject this hypothesis. To test the second hypothesis, the student could check if the lights in the classroom are functional. If so, there is no power failure and the student should reject this hypothesis. The students should test each hypothesis by carrying out appropriate experiments. Be aware that rejecting one hypothesis does not determine whether or not one can accept the other hypotheses. It simply eliminates one hypothesis that is not valid ( Figure 1.6 ). Using the scientific method, the student rejects the hypotheses that are inconsistent with experimental data.

While this “warm classroom” example is based on observational results, other hypotheses and experiments might have clearer controls. For instance, a student might attend class on Monday and realize she had difficulty concentrating on the lecture. One observation to explain this occurrence might be, “When I eat breakfast before class, I am better able to pay attention.” The student could then design an experiment with a control to test this hypothesis.

In hypothesis-based science, researchers predict specific results from a general premise. We call this type of reasoning deductive reasoning: deduction proceeds from the general to the particular. However, the reverse of the process is also possible: sometimes, scientists reach a general conclusion from a number of specific observations. We call this type of reasoning inductive reasoning, and it proceeds from the particular to the general. Researchers often use inductive and deductive reasoning in tandem to advance scientific knowledge ( Figure 1.7 ). In recent years a new approach of testing hypotheses has developed as a result of an exponential growth of data deposited in various databases. Using computer algorithms and statistical analyses of data in databases, a new field of so-called "data research" (also referred to as "in silico" research) provides new methods of data analyses and their interpretation. This will increase the demand for specialists in both biology and computer science, a promising career opportunity.

Visual Connection

In the example below, the scientific method is used to solve an everyday problem. Match the scientific method steps (numbered items) with the process of solving the everyday problem (lettered items). Based on the results of the experiment, is the hypothesis correct? If it is incorrect, propose some alternative hypotheses.

Decide if each of the following is an example of inductive or deductive reasoning.

• All flying birds and insects have wings. Birds and insects flap their wings as they move through the air. Therefore, wings enable flight.
• Insects generally survive mild winters better than harsh ones. Therefore, insect pests will become more problematic if global temperatures increase.
• Chromosomes, the carriers of DNA, are distributed evenly between the daughter cells during cell division. Therefore, each daughter cell will have the same chromosome set as the mother cell.
• Animals as diverse as humans, insects, and wolves all exhibit social behavior. Therefore, social behavior must have an evolutionary advantage.

The scientific method may seem too rigid and structured. It is important to keep in mind that, although scientists often follow this sequence, there is flexibility. Sometimes an experiment leads to conclusions that favor a change in approach. Often, an experiment brings entirely new scientific questions to the puzzle. Many times, science does not operate in a linear fashion. Instead, scientists continually draw inferences and make generalizations, finding patterns as their research proceeds. Scientific reasoning is more complex than the scientific method alone suggests. Notice, too, that we can apply the scientific method to solving problems that aren’t necessarily scientific in nature.

Two Types of Science: Basic Science and Applied Science

The scientific community has been debating for the last few decades about the value of different types of science. Is it valuable to pursue science for the sake of simply gaining knowledge, or does scientific knowledge only have worth if we can apply it to solving a specific problem or to bettering our lives? This question focuses on the differences between two types of science: basic science and applied science.

Basic science or “pure” science seeks to expand knowledge regardless of the short-term application of that knowledge. It is not focused on developing a product or a service of immediate public or commercial value. The immediate goal of basic science is knowledge for knowledge’s sake, although this does not mean that, in the end, it may not result in a practical application.

In contrast, applied science or “technology,” aims to use science to solve real-world problems, making it possible, for example, to improve a crop yield, find a cure for a particular disease, or save animals threatened by a natural disaster ( Figure 1.8 ). In applied science, the problem is usually defined for the researcher.

Some individuals may perceive applied science as “useful” and basic science as “useless.” A question these people might pose to a scientist advocating knowledge acquisition would be, “What for?” However, a careful look at the history of science reveals that basic knowledge has resulted in many remarkable applications of great value. Many scientists think that a basic understanding of science is necessary before researchers develop an application, therefore, applied science relies on the results that researchers generate through basic science. Other scientists think that it is time to move on from basic science in order to find solutions to actual problems. Both approaches are valid. It is true that there are problems that demand immediate attention; however, scientists would find few solutions without the help of the wide knowledge foundation that basic science generates.

One example of how basic and applied science can work together to solve practical problems occurred after the discovery of DNA structure led to an understanding of the molecular mechanisms governing DNA replication. DNA strands, unique in every human, are in our cells, where they provide the instructions necessary for life. When DNA replicates, it produces new copies of itself, shortly before a cell divides. Understanding DNA replication mechanisms enabled scientists to develop laboratory techniques that researchers now use to identify genetic diseases, pinpoint individuals who were at a crime scene, and determine paternity. Without basic science, it is unlikely that applied science could exist.

Another example of the link between basic and applied research is the Human Genome Project, a study in which researchers analyzed and mapped each human chromosome to determine the precise sequence of DNA subunits and each gene's exact location. (The gene is the basic unit of heredity represented by a specific DNA segment that codes for a functional molecule. An individual’s complete collection of genes is their genome.) Researchers have studied other less complex organisms as part of this project in order to gain a better understanding of human chromosomes. The Human Genome Project ( Figure 1.9 ) relied on basic research with simple organisms and, later, with the human genome. An important end goal eventually became using the data for applied research, seeking cures and early diagnoses for genetically related diseases.

While scientists usually carefully plan research efforts in both basic science and applied science, note that some discoveries are made by serendipity , that is, by means of a fortunate accident or a lucky surprise. Scottish biologist Alexander Fleming discovered penicillin when he accidentally left a petri dish of Staphylococcus bacteria open. An unwanted mold grew on the dish, killing the bacteria. Fleming's curiosity to investigate the reason behind the bacterial death, followed by his experiments, led to the discovery of the antibiotic penicillin, which is produced by the fungus Penicillium . Even in the highly organized world of science, luck—when combined with an observant, curious mind—can lead to unexpected breakthroughs.

Reporting Scientific Work

Whether scientific research is basic science or applied science, scientists must share their findings in order for other researchers to expand and build upon their discoveries. Collaboration with other scientists—when planning, conducting, and analyzing results—is important for scientific research. For this reason, important aspects of a scientist’s work are communicating with peers and disseminating results to peers. Scientists can share results by presenting them at a scientific meeting or conference, but this approach can reach only the select few who are present. Instead, most scientists present their results in peer-reviewed manuscripts that are published in scientific journals. Peer-reviewed manuscripts are scientific papers that a scientist’s colleagues or peers review. These colleagues are qualified individuals, often experts in the same research area, who judge whether or not the scientist’s work is suitable for publication. The process of peer review helps to ensure that the research in a scientific paper or grant proposal is original, significant, logical, and thorough. Grant proposals, which are requests for research funding, are also subject to peer review. Scientists publish their work so other scientists can reproduce their experiments under similar or different conditions to expand on the findings.

A scientific paper is very different from creative writing. Although creativity is required to design experiments, there are fixed guidelines when it comes to presenting scientific results. First, scientific writing must be brief, concise, and accurate. A scientific paper needs to be succinct but detailed enough to allow peers to reproduce the experiments.

The scientific paper consists of several specific sections—introduction, materials and methods, results, and discussion. This structure is sometimes called the “IMRaD” format. There are usually acknowledgment and reference sections as well as an abstract (a concise summary) at the beginning of the paper. There might be additional sections depending on the type of paper and the journal where it will be published. For example, some review papers require an outline.

The introduction starts with brief, but broad, background information about what is known in the field. A good introduction also gives the rationale of the work. It justifies the work carried out and also briefly mentions the end of the paper, where the researcher will present the hypothesis or research question driving the research. The introduction refers to the published scientific work of others and therefore requires citations following the style of the journal. Using the work or ideas of others without proper citation is plagiarism .

The materials and methods section includes a complete and accurate description of the substances the researchers use, and the method and techniques they use to gather data. The description should be thorough enough to allow another researcher to repeat the experiment and obtain similar results, but it does not have to be verbose. This section will also include information on how the researchers made measurements and the types of calculations and statistical analyses they used to examine raw data. Although the materials and methods section gives an accurate description of the experiments, it does not discuss them.

Some journals require a results section followed by a discussion section, but it is more common to combine both. If the journal does not allow combining both sections, the results section simply narrates the findings without any further interpretation. The researchers present results with tables or graphs, but they do not present duplicate information. In the discussion section, the researchers will interpret the results, describe how variables may be related, and attempt to explain the observations. It is indispensable to conduct an extensive literature search to put the results in the context of previously published scientific research. Therefore, researchers include proper citations in this section as well.

Finally, the conclusion section summarizes the importance of the experimental findings. While the scientific paper almost certainly answers one or more scientific questions that the researchers stated, any good research should lead to more questions. Therefore, a well-done scientific paper allows the researchers and others to continue and expand on the findings.

Review articles do not follow the IMRAD format because they do not present original scientific findings, or primary literature. Instead, they summarize and comment on findings that were published as primary literature and typically include extensive reference sections.

Scientific Ethics

Scientists must ensure that their efforts do not cause undue damage to humans, animals, or the environment. They also must ensure that their research and communications are free of bias and that they properly balance financial, legal, safety, replicability, and other considerations. All scientists -- and many people in other fields -- have these ethical obligations, but those in the life sciences have a particular obligation because their research may involve people or other living things. Bioethics is thus an important and continually evolving field, in which researchers collaborate with other thinkers and organizations. They work to define guidelines for current practice, and also continually consider new developments and emerging technologies in order to form answers for the years and decades to come.

For example, bioethicists may examine the implications of gene editing technologies, including the ability to create organisms that may displace others in the environment, as well as the ability to “design” human beings. In that effort, ethicists will likely seek to balance the positive outcomes -- such as improved therapies or prevention of certain illnesses -- with negative outcomes.

Unfortunately, the emergence of bioethics as a field came after a number of clearly unethical practices, where biologists did not treat research subjects with dignity and in some cases did them harm. In the 1932 Tuskegee syphilis study, 399 African American men were diagnosed with syphilis but were never informed that they had the disease, leaving them to live with and pass on the illness to others. Doctors even withheld proven medications because the goal of the study was to understand the impact of untreated syphilis on Black men.

While the decisions made in the Tuskegee study are unjustifiable, some decisions are genuinely difficult to make. Bioethicists work to establish moral and dignifying approaches before such decisions come to pass. For example, doctors rely on artificial intelligence and robotics for medical diagnosis and treatment; in the near future, even more responsibility will lie with machines. Who will be responsible for medical decisions? Who will explain to families if a procedure doesn’t go as planned? And, since such treatments will likely be expensive, who will decide who has access to them and who does not? These are all questions bioethicists seek to answer, and are the types of considerations that all scientific researchers take into account when designing and conducting studies.

Bioethics are not simple, and often leave scientists balancing benefits with harm. In this text and course, you will discuss medical discoveries, vaccines, and research that, at their core, have an ethical complexity or, in the view of many, an ethical lapse. In 1951, Henrietta Lacks , a 30-year-old African American woman, was diagnosed with cervical cancer at Johns Hopkins Hospital. Unique characteristics of her illnesses gave her cells the ability to divide continuously, essentially making them “immortal.” Without her knowledge or permission, researchers took samples of her cells and with them created the immortal HeLa cell line. These cells have contributed to major medical discoveries, including the polio vaccine. Many researchers mentioned in subsequent sections of the text relied on HeLa cell research as at least a component of their work related to cancer, AIDS, cell aging, and even very recently in COVID-19 research.

Today, harvesting tissue or organs from a dying patient without consent is not only considered unethical but illegal, regardless of whether such an act could save other patients’ lives. Is it ethical, then, for scientists to continue to use Lacks’s tissues for research, even though they were obtained illegally by today’s standards? Should Lacks be mentioned as a contributor to the research based on her cells, and should she be cited in the several Nobel Prizes that have been awarded through such work? Finally, should medical companies be obligated to pay Lacks’ family (which had financial difficulties) a portion of the billions of dollars in revenue earned through medicines that benefited from HeLa cell research? How would Henrietta Lacks feel about this? Because she was never asked, we will never know.

To avoid such situations, the role of ethics in scientific research is to ask such questions before, during, and after research or practice takes place, as well as to adhere to established professional principles and consider the dignity and safety of all organisms involved or affected by the work.

Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. Although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life. Since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.

From its earliest beginnings, biology has wrestled with three questions: What are the shared properties that make something “alive”? Once we know something is alive, how do we find meaningful levels of organization in its structure? Finally, when faced with the remarkable diversity of life, how do we organize the different kinds of organisms so that we can better understand them? As scientists discover new organisms every day, biologists continue to seek answers to these and other questions.

Properties of Life

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, regulation, homeostasis, energy processing, and evolution. When viewed together, these nine characteristics serve to define life.

Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms comprise molecules. These in turn comprise cell organelles and other cellular inclusions. In multicellular organisms ( Figure ), similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems.

Sensitivity or Response to Stimuli

Organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch ( Figure ). Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis ) or light ( phototaxis ). Movement toward a stimulus is a positive response, while movement away from a stimulus is a negative response.

Link to Learning

Watch this video to see how plants respond to a stimulus—from opening to light, to wrapping a tendril around a branch, to capturing prey.

Reproduction

Single-celled organisms reproduce by first duplicating their DNA, and then dividing it equally as the cell prepares to divide to form two new cells. Multicellular organisms often produce specialized reproductive germline, gamete, oocyte, and sperm cells. After fertilization (the fusion of an oocyte and a sperm cell), a new individual develops. When reproduction occurs, DNA containing genes are passed along to an organism’s offspring. These genes ensure that the offspring will belong to the same species and will have similar characteristics, such as size and shape.

Growth and Development

Organisms grow and develop as a result of genes providing specific instructions that will direct cellular growth and development. This ensures that a species’ young ( Figure ) will grow up to exhibit many of the same characteristics as its parents.

Even the smallest organisms are complex and require multiple regulatory mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stresses. Two examples of internal functions regulated in an organism are nutrient transport and blood flow. Organs (groups of tissues working together) perform specific functions, such as carrying oxygen throughout the body, removing wastes, delivering nutrients to every cell, and cooling the body.

In order to function properly, cells require appropriate conditions such as proper temperature, pH, and appropriate concentration of diverse chemicals. These conditions may, however, change from one moment to the next. Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes, through homeostasis (literally, “steady state”). For example, an organism needs to regulate body temperature through the thermoregulation process. Organisms that live in cold climates, such as the polar bear ( Figure ), have body structures that help them withstand low temperatures and conserve body heat. Structures that aid in this type of insulation include fur, feathers, blubber, and fat. In hot climates, organisms have methods (such as perspiration in humans or panting in dogs) that help them to shed excess body heat.

Energy Processing

All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food. Others use chemical energy in molecules they take in as food ( Figure ).

Levels of Organization of Living Things

Living things are highly organized and structured, following a hierarchy that we can examine on a scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms form molecules. A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds. Many molecules that are biologically important are macromolecules , large molecules that are typically formed by polymerization (a polymer is a large molecule that is made by combining smaller units called monomers, which are simpler than macromolecules). An example of a macromolecule is deoxyribonucleic acid (DNA) ( Figure ), which contains the instructions for the structure and functioning of all living organisms.

Watch this video that animates the three-dimensional structure of the DNA molecule in Figure .

Some cells contain aggregates of macromolecules surrounded by membranes. We call these organelles . Organelles are small structures that exist within cells. Examples of organelles include mitochondria and chloroplasts, which carry out indispensable functions: mitochondria produce energy to power the cell, while chloroplasts enable green plants to utilize the energy in sunlight to make sugars. All living things are made of cells. The cell itself is the smallest fundamental unit of structure and function in living organisms. (This requirement is why scientists do not consider viruses living: they are not made of cells. To make new viruses, they have to invade and hijack the reproductive mechanism of a living cell. Only then can they obtain the materials they need to reproduce.) Some organisms consist of a single cell and others are multicellular. Scientists classify cells as prokaryotic or eukaryotic. Prokaryotes are single-celled or colonial organisms that do not have membrane-bound nuclei. In contrast, the cells of eukaryotes do have membrane-bound organelles and a membrane-bound nucleus.

In larger organisms, cells combine to make tissues , which are groups of similar cells carrying out similar or related functions. Organs are collections of tissues grouped together performing a common function. Organs are present not only in animals but also in plants. An organ system is a higher level of organization that consists of functionally related organs. Mammals have many organ systems. For instance, the circulatory system transports blood through the body and to and from the lungs. It includes organs such as the heart and blood vessels. Organisms are individual living entities. For example, each tree in a forest is an organism. Single-celled prokaryotes and single-celled eukaryotes are also organisms, which biologists typically call microorganisms.

Biologists collectively call all the individuals of a species living within a specific area a population . For example, a forest may include many pine trees, which represent the population of pine trees in this forest. Different populations may live in the same specific area. For example, the forest with the pine trees includes populations of flowering plants, insects, and microbial populations. A community is the sum of populations inhabiting a particular area. For instance, all of the trees, flowers, insects, and other populations in a forest form the forest’s community. The forest itself is an ecosystem. An ecosystem consists of all the living things in a particular area together with the abiotic, nonliving parts of that environment such as nitrogen in the soil or rain water. At the highest level of organization ( Figure ), the biosphere is the collection of all ecosystems, and it represents the zones of life on Earth. It includes land, water, and even the atmosphere to a certain extent.

The Diversity of Life

The fact that biology, as a science, has such a broad scope has to do with the tremendous diversity of life on earth. The source of this diversity is evolution , the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems.

A phylogenetic tree ( Figure ) can summarize the evolution of various life forms on Earth. It is a diagram showing the evolutionary relationships among biological species based on similarities and differences in genetic or physical traits or both. Nodes and branches comprise a phylogenetic tree. The internal nodes represent ancestors and are points in evolution when, based on scientific evidence, researchers believe an ancestor has diverged to form two new species. The length of each branch is proportional to the time elapsed since the split.

Evolution Connection

Carl Woese and the Phylogenetic Tree In the past, biologists grouped living organisms into five kingdoms: animals, plants, fungi, protists, and bacteria. They based the organizational scheme mainly on physical features, as opposed to physiology, biochemistry, or molecular biology, all of which modern systematics use. American microbiologist Carl Woese's pioneering work in the early 1970s has shown, however, that life on Earth has evolved along three lineages, now called domains—Bacteria, Archaea, and Eukarya. The first two are prokaryotic cells with microbes that lack membrane-enclosed nuclei and organelles. The third domain contains the eukaryotes and includes unicellular microorganisms (protists), together with the three remaining kingdoms (fungi, plants, and animals). Woese defined Archaea as a new domain, and this resulted in a new taxonomic tree ( Figure ). Many organisms belonging to the Archaea domain live under extreme conditions and are called extremophiles. To construct his tree, Woese used genetic relationships rather than similarities based on morphology (shape).

Woese constructed his tree from universally distributed comparative gene sequencing that are present in every organism, and conserved (meaning that these genes have remained essentially unchanged throughout evolution). Woese’s approach was revolutionary because comparing physical features are insufficient to differentiate between the prokaryotes that appear fairly similar in spite of their tremendous biochemical diversity and genetic variability ( Figure ). Comparing homologous DNA and RNA sequences provided Woese with a sensitive device that revealed the extensive variability of prokaryotes, and which justified separating the prokaryotes into two domains: bacteria and archaea.

Branches of Biological Study

The scope of biology is broad and therefore contains many branches and subdisciplines. Biologists may pursue one of those subdisciplines and work in a more focused field. For instance, molecular biology and biochemistry study biological processes at the molecular and chemical level, including interactions among molecules such as DNA, RNA, and proteins, as well as the way they are regulated. Microbiology , the study of microorganisms, is the study of the structure and function of single-celled organisms. It is quite a broad branch itself, and depending on the subject of study, there are also microbial physiologists, ecologists, and geneticists, among others.

Career Connection

Forensic Scientist Forensic science is the application of science to answer questions related to the law. Biologists as well as chemists and biochemists can be forensic scientists. Forensic scientists provide scientific evidence for use in courts, and their job involves examining trace materials associated with crimes. Interest in forensic science has increased in the last few years, possibly because of popular television shows that feature forensic scientists on the job. Also, developing molecular techniques and establishing DNA databases have expanded the types of work that forensic scientists can do. Their job activities are primarily related to crimes against people such as murder, rape, and assault. Their work involves analyzing samples such as hair, blood, and other body fluids and also processing DNA ( Figure ) found in many different environments and materials. Forensic scientists also analyze other biological evidence left at crime scenes, such as insect larvae or pollen grains. Students who want to pursue careers in forensic science will most likely have to take chemistry and biology courses as well as some intensive math courses.

Another field of biological study, neurobiology , studies the biology of the nervous system, and although it is a branch of biology, it is also an interdisciplinary field of study known as neuroscience. Because of its interdisciplinary nature, this subdiscipline studies different nervous system functions using molecular, cellular, developmental, medical, and computational approaches.

Paleontology , another branch of biology, uses fossils to study life’s history ( Figure ). Zoology and botany are the study of animals and plants, respectively. Biologists can also specialize as biotechnologists, ecologists, or physiologists, to name just a few areas. This is just a small sample of the many fields that biologists can pursue.

Biology is the culmination of the achievements of the natural sciences from their inception to today. Excitingly, it is the cradle of emerging sciences, such as the biology of brain activity, genetic engineering of custom organisms, and the biology of evolution that uses the laboratory tools of molecular biology to retrace the earliest stages of life on Earth. A scan of news headlines—whether reporting on immunizations, a newly discovered species, sports doping, or a genetically-modified food—demonstrates the way biology is active in and important to our everyday world.

Section Summary

Biology is the science of life. All living organisms share several key properties such as order, sensitivity or response to stimuli, reproduction, growth and development, regulation, homeostasis, and energy processing. Living things are highly organized parts of a hierarchy that includes atoms, molecules, organelles, cells, tissues, organs, and organ systems. In turn, biologists group organisms as populations, communities, ecosystems, and the biosphere. The great diversity of life today evolved from less-diverse ancestral organisms over billions of years. We can use a phylogenetic tree to show evolutionary relationships among organisms.

Biology is very broad and includes many branches and subdisciplines. Examples include molecular biology, microbiology, neurobiology, zoology, and botany, among others.

Free Response

Select two items that biologists agree are necessary in order to consider an organism “alive.” For each, give an example of a nonliving object that otherwise fits the definition of “alive.”

Answers will vary. Layers of sedimentary rock have order but are not alive. Technology is capable of regulation but is not, of itself, alive.

Consider the levels of organization of the biological world, and place each of these items in order from smallest level of organization to most encompassing: skin cell, elephant, water molecule, planet Earth, tropical rainforest, hydrogen atom, wolf pack, liver.

Smallest level of organization to largest: hydrogen atom, water molecule, skin cell, liver, elephant, wolf pack, tropical rainforest, planet Earth

You go for a long walk on a hot day. Give an example of a way in which homeostasis keeps your body healthy.

During your walk, you may begin to perspire, which cools your body and helps your body to maintain a constant internal temperature. You might also become thirsty and pause long enough for a cool drink, which will help to restore the water lost during perspiration.

Using examples, explain how biology can be studied from a microscopic approach to a global approach.

Researchers can approach biology from the smallest to the largest, and everything in between. For instance, an ecologist may study a population of individuals, the population’s community, the community’s ecosystem, and the ecosystem’s part in the biosphere. When studying an individual organism, a biologist could examine the cell and its organelles, the tissues that the cells make up, the organs and their respective organ systems, and the sum total—the organism itself.

Writing assignment.

The writing assignment can either be a literature review or a research proposal. The purpose of the literature review is to perform an in-depth analysis of the literature surrounding a certain topic or research field and to integrate it with your own perspective on the matter. The purpose of the research proposal is to present the relevance of a certain research problem based on current literature as well as develop a plan on how this research can be conducted. 

Thesis Support Skills Lab Are you working on your writing assignment? There is a lot that can help you! Skills Lab provides an overview of all offerings within UU on the thesis support page . For example, you will find information on individual writing tutoring, webinars, workshops, thesis groups and more. Would you like to stay up to date? Subscribe to the thesis support newsletter via the following link: keep me informed thesis support .

A writing assignment consists of several key stages: defining the topic, formulating a hypothesis, drawing up a timetable, literature research, and the writing phase. 

You can choose between 2 formats: 

• A literature review: a review paper in the relevant research field. The review include an in-depth discussion, in which you demonstrate your ability to critically evaluate hypotheses and results, present your own views, and draw conclusions that point towards new research opportunities. The review must also include a plain language summary (in Dutch or English, 500 words, high school biology or science level). A review format suitable for a relevant international peer-reviewed journal of high standard should be used. 
• A research proposal: the format of a research funding application for a PhD position. You will use an adapted version of the NWO Open Competition Domain Science – M grant application form. Download the template for the research proposal here.

The body of the text (excl. legends, tables, footnotes, references, etc.) should typically be 6000– 8000 words long. It should be emphasized that the content is more important than the number of words. The assignment should include minimally 25 and maximally 60 references. 

Five weeks of full-time study (7.5 EC) are scheduled for the writing assignment. The writing assignment can be done part-time and the end date should be calculated accordingly, however even in a part-time set-up we encourage you to finish the writing assignment within 3 months. 

To meet the deadline, the scope of the assignment should be limited and clearly defined, you should work diligently, and the agreements between you and your supervisor about the content and scope of the assignment should be clear. A clear time schedule will help you to finish in time. During the first meeting with your supervisor, dates should be set for discussion of the writing plan, discussion of the first draft, and feedback on the final version.  

You must submit the final version of your writing assignment for assessment to your examiner by the end date. After the end date, you have 20 additional working days to wrap up some last details without the need to request an official extension. If you are unable to submit within that timeframe for exceptional reasons, you should request the rescheduling of your end date (see extension and delay below). After submission of your writing assignment, your examiner has 10 working days to submit the final assessment in OSIRIS Case (with input from your second reviewer or your supervisor of the host institute).

Learning outcomes

After finishing your writing assignment you are capable of independently: 

• Conducting literature research, using scientific secure literature databases (e.g. PubMed); 
• Using scientific literature and insights in a critical manner;
• Summarizing literature using own words;
• Integrating results and models of papers read into new models; 
• Formulating hypotheses for future research.

Writing assignments outside UU/UMCU

Writing assignments outside UU/UMCU require signing of an internship contract. More information can be found below in the section External writing assignment / going abroad.

4. Interim assessment

An interim assessment is not mandatory, but it is important to evaluate your work and progress with your supervisor on a regular basis. To discuss your progress the rubric for  literature reviews  or  research proposals  can be used. 

5. Final assessment

Fraud and plagiarism .

Your written report will be checked for plagiarism via Ouriginal . Upload the final version of your report as a Word file without your reference list to Ouriginal. Use  this site for information and instructions . You can do this yourself or your examiner can upload your report. If there are any restrictions on publication, the supervisor/examiner should upload the final report themselves so that it can be done under embargo.

The report (summary) from Ouriginal should be uploaded in OSIRIS Case by your examiner during the final assessment.

Is the percentage of matching text found by Ouriginal >10%? The examiner should write an explanation why this is not due to plagiarism and upload this in OSIRIS Case as well.

The use of the services as described in this paper - contract cheating sites - is considered as plagiarism by the BoE. The examiner should take all the written versions of the student into account.

The examiner has to provide a motivation for the final grade and upload this motivation in OSIRIS Case during the final assessment. The rubric for the   literature review  or research proposal  can be used.

Assessment form and procedure 

Since September 2022 the registration of writing assignments is digitalised in OSIRIS Case. Did you start your writing assignment before 2022 and is it not registered in OSIRIS Case? Please use the assessment method described below.

You examiner has to complete the final assessment form in OSIRIS Case, including the plagiarism report and the motivation of the grades. For more information, please check the  OSIRIS Case examiner manual . The second reviewer or supervisor host institute will receive a notification from OSIRIS Case once the form has been completed and is asked to approve the final assessment. 

OSIRIS Thesis Archive 

All written reports will be archived in OSIRIS Thesis Archive. After the final assessment form is completed in OSIRIS Case, you will receive an e-mail, asking you to upload your report .

Additionally, you can choose to publish your thesis, including the timing and version to publish. The theses become open-access after the publication date and can be found through search engines like Google and WorldCat. Together with your examiner and supervisor you agree upon and decide if, when, and how your thesis will be published.

Please note: the title of your report is literally copied to your international diploma supplement, so be aware of the correct use of capitals in the title.

Practical information

External writing assignment / going abroad.

The preparation and application of an writing assignment outside UU/UMCU or a writing assignment abroad is similar to a writing assignment within the UU/UMCU. You require an examiner from the UU/UMCU and the approval from the Board of Examiners. Your examiner and supervisor host institute both have to approve your research project in OSIRIS Case.

Writing assignments outside UU/UMCU require signing of the internship contract that is integrated in OSIRIS Case. During the application process in OSIRIS Case ,  the contract appears and will be signed as part of the process. No further action from your side is required.

If your institute is providing you with a different contract, please email it to  [email protected]  and submit the fully signed contract in OSIRIS Case.

Questions about the internship contract? Email:  [email protected]   During your writing assignment, stay in touch with your examiner.

Going abroad? Start on time!

If you would like to do a writing assignment abroad, we strongly advise you to start in time to arrange things for your leave. For more information on studying abroad check this site . Please also check the following site containing  general information on going abroad during your studies  and consult the  international officers  in case of questions.

Extension and delay

A writing assignment cannot be extended for more credits. 

Exceeding the original end-date 

If you exceed your original end date by more than 20 working days, you should request a new end date. To do this send an e-mail to your  research project coordinator  with a document attached (signed by your examiner) that includes: 

• A valid motivation for the delay. If your motivation contains matters of privacy an e-mail from your academic counsellor supporting your request will suffice; 
• A solid plan containing a time schedule and the new end date. 

Valid reasons for postponing the end date include: more time spent on courses, extra time off due to personal circumstances, or if your examiner/supervisor needs more time due to personal circumstances. If your personal circumstances are playing a role, please make sure you contact the academic counsellors before submitting your request since they will be asked to confirm the ‘force majeure’ of the request.

Changes within the project

Changes in the title of the project do no have to be communicated to the Board of Examiners. 

In case of changes in the topic of the project, examiner, second reviewer/supervisor host institute or daily supervisor you should fill in the request for changes form  (download and open in Adobe Reader) and email it directly to the administration office . 

The Board of Examiners will check whether the new examiner or second reviewer/supervisor host institute meets the requirements. The Master's administration office will inform you about their decision.

You will always be writing your assignment under experienced supervision, and your assignment will often be part of a larger framework/project. By signing the application form, you declare to transfer the copyright of all products (including the tangible and intellectual products) of the assignment to the UU/UMCU or host institute. Depending on the magnitude of the scientific contribution, you have the right to be a (co-)author of publications or to be otherwise acknowledged. Any questions in this regard should be addressed to the head of the research group. 

It is not uncommon for a students’ writing assignments to form the basis for a scientific article. Writing a scientific article is a difficult skill to master. Make sure you finish your writing assignment and have this assessed, before you start writing a possible review article which will then be used for publication. You can decide to work on it outside of your writing assignment (e.g., as a mini project in electives) so it does not cause you study delay. 

Please note that the product you will hand in to the school should be an individual product. That means it cannot be edited for publication by your examiners or other co-authors. Of course, you can receive feedback. If your examiner decides to publish the report as a review, the examiner may rewrite it after you handed in your individual report.

‘Life’ in the Lab

Growing chemical gardens. Searching for life’s building blocks in meteorites. Sketching out a path to exotic life on a moon of Saturn.

Interplanetary probes and space telescopes take the search for life beyond Earth to new heights. But just as indispensable is the laboratory work on Earth itself. Experimenters seek to puzzle out the chemical origins of life, or capture evidence of molecules common to living things in samples from other objects in the solar system.

Some even have kickstarted Darwinian evolution in a test-tube. The process of natural selection, made famous by Charles Darwin, was seen in the well-known experiment, and appeared to meet, at least technically, NASA’s working definition of life: “a self-sustaining chemical system capable of Darwinian evolution.”

NASA scientists are part of a global push to understand how life began on our planet, how it might develop on others, and how we can use technology to detect it, within our solar system or in the stars beyond.

“My origin-of-life work is focused on how to get from a geochemical environment to the start of organic chemistry,” said Laurie Barge, co-leader of the Origins and Habitability Lab at NASA’s Jet Propulsion Laboratory in Southern California. “We don’t know what pieces of the first life came when. What came first? What came later? Was it before or after the cell emerged?”

Barge is known for chemical gardens – flasks full of materials that attempt to simulate the environment, chemistry and even the electrical charge of hydrothermal vents on the floors of primordial oceans. They’re designed to explore how metabolism, a critical component of all life, might have chugged into operation in such vents some 4 billion years ago.

It's only one of several scenarios astrobiologists have suggested as early paths to eventual life, and metabolism is not even life itself – just a way of turning organic compounds into energy, a baseline requirement for any living thing. The process later might have been co-opted by opportunistic, incipient life forms, though no one knows just how that could have happened.

These hydrothermal vents, or “chimneys,” also might be present on the sea floor of Saturn’s moon, Enceladus, or other “ocean worlds” that hide global oceans under shells of ice.

“These chimneys on the early Earth, also Enceladus: What types of environments, what sort of chemistry do those drive?” Barge asks. “What kind of energy do they generate?”

Whether the elements of eventual life began on a sea floor or, say, a pond on the land surface, they might have been infused with ingredients delivered from above.

Rocks as Time Travelers

While we can’t travel back in time to early Earth, many asteroids have remained unchanged for billions of years, making them akin to time capsules of the infant solar system. What’s more, pieces of space rocks that fall to Earth, called meteorites, also contain clues about the building blocks of early planets, and maybe even life.

At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, Jason Dworkin, senior scientist for astrobiology, is investigating the composition and chemistry of meteorites.

Dworkin’s lab also analyzes samples of other solar system bodies returned to Earth by missions like Hayabusa2 from the Japanese space agency, JAXA, NASA’s Stardust , and Apollo , and soon-to-be-delivered asteroid samples from NASA’s OSIRIS-REx .

Organic compounds in rocks from space, though not signs of biology in themselves, might have been important to the origin of life on Earth – especially in the early period after Earth’s formation, when large asteroids were striking the surface more frequently.

“We try to understand the chemistry that could have been happening on Earth,” Dworkin said. “Though we know extraterrestrial material was raining down on Earth, we don’t know how important it was for life. We don’t know if it was a major or minor component, or the silver bullet that caused it to happen.”

Still, research by Dworkin and others has yielded potentially significant clues. In 2009, his lab was the first to detect an amino acid called glycine – a building block of life – in a comet, after analyzing samples returned by NASA’s Stardust spacecraft.

A more recent sample return in 2020, material from the rocky Ryugu asteroid delivered by Hayabusa2, provided evidence of amino acids, sulfur compounds, and even uracil, an important informational unit in the RNA found in Earth life, and niacin, a form of vitamin B3.

And OSIRIS-REx, now carrying a sample of material from the asteroid Bennu back to Earth, already has revealed veins of carbonate on the asteroid’s surface. The sample could shed light on the chemistry of such bodies, perhaps analogous to early chemistry on Earth.

Even the composition of asteroids could offer insight into the early formation of Earth and other planets.

The coming Artemis missions, taking humans back to the Moon, will include collection of samples by Artemis III; another planned “Sample Return” mission to Mars will gather cached sample tubes and bring them back to Earth.

“I love being able to look at a sample directly from an object, and interrogate that,” Dworkin said. “With Hayabusa2, OSIRIS-REx, Artemis III coming up, Mars sample-return coming up, there’s going to be so much to look at. We’ll do comparative geochemistry, comparative astrobiology, across different objects.”

Titan on Earth

Within the solar system or beyond, another intriguing – if perhaps less likely – possibility is sometimes called “life as we don’t know it:” life-forms based on unfamiliar molecular components, or using a solvent other than water. Saturn’s moon, Titan, often has been cited as a potential environment for such exotic forms.

Titan’s surface is in such a deep freeze that water is essentially rock. Yet the moon has a thick atmosphere, lakes, rivers, and precipitation – the only solar system body other than Earth with such a liquid cycle.

The lakes and rivers are composed of methane and ethane. Could some form of life thrive on these liquids, as Earth life does on water?

Laboratory work has provided some surprising clues. Titan’s extremely low surface temperatures – minus 290 degrees Fahrenheit (minus 179 Celsius) – make heat energy for chemistry hard to come by. And chemical reactions require liquid to act as a solvent, though methane has proven to be a poor one, ethane only marginally better, said Jonathan Lunine, an astronomy professor at Cornell University who has studied possible paths of chemistry on Titan’s surface.

“If you can’t get things dissolved in a liquid, not much is going to happen,” Lunine said.

But experiments by researchers at JPL showed that, at least under some conditions, organic material can condense out of these liquids. One possibility involves precipitation from these liquids of crystal structures. The structures could then act as templates to form similar crystals, in essence reproducing themselves.

“Maybe stuff like that would lead to something sort of lifelike,” said Robert Hodyss, a laboratory studies group supervisor at JPL.

The lab work is suggestive, he said, but much more data will be needed from Titan itself. That is expected to come from NASA’s Dragonfly spacecraft, a dual-quadcopter that will fly from site to site on Titan’s surface to conduct some “lab work” of its own. Dragonfly is expected to reach the smoggy moon in the mid 2030s after a seven-year journey.

“The Dragonfly mission is looking for prebiotic molecules that look familiar to us,” said Melissa Trainer at NASA Goddard, the deputy principal investigator for the mission. “We’re looking at the chemical inventory once we get there, to get an idea of relative abundances, the context in which we find them.”

That will allow investigators to interpret the findings, and perhaps determine whether the molecules and chemistry suggest the potential for life. “We could see an indication, with our best understanding, that could be relevant for some kind of biochemistry, even if it’s one that isn’t familiar,” she said.

Evidence of exotic life forms thriving on methane or ethane, however, might be difficult to detect, even if they somehow developed on Titan’s surface.

“Once you get into ‘life as we don’t know it,’ there are a lot of open questions there,” Trainer said.

Yet Titan – like Jupiter’s moon, Europa, or Saturn’s Enceladus – also is likely to be an ocean world, harboring liquid water beneath an ice-covered surface. That raises another possibility: organic material from the surface pushed deep into the moon, making contact with the subsurface ocean and, finding higher temperatures and pressures, interacting in ways that could produce a habitable environment.

Scientists also have proposed that surface impacts could drive organics from the surface into the underlying ocean.

Or, Trainer said, such an impact, or even volcanic eruptions of frozen material – “cryovolcanoes” – could create warm conditions allowing liquid water environments to thrive for a time. Lab work has shown that compounds containing carbon, hydrogen, and nitrogen that might be building blocks of biochemistry could accumulate on the surface under such conditions.

How Life Began

While such findings can yield key insights, astrobiology in the lab is not limited to creation of potentially habitable conditions, exotic or otherwise. Other experiments explore pathways to the start of life itself.

Among the best known of these was conducted by Gerald Joyce, a research professor at the Salk Institute in La Jolla, California, and collaborator Tracey Lincoln. They created an RNA-based system, then coaxed it into sustained Darwinian evolution in a test-tube. Lincoln, lead author and Joyce’s PhD student at the time, published the finding in 2009.

Although it technically met NASA’s working definition of life – a self-sustaining chemical system capable of Darwinian evolution – Joyce says that in his view, it still didn’t qualify as a true life-form.

“I was the first to say, ‘It doesn’t make it,’” Joyce said. Left to its own, the system, with its fragile, low-capacity RNA molecule, would hardly be able to evolve from where it started.

“It wouldn’t have been too long till it was dead,” he said. “There was just not enough information carrying capacity” in the relatively short strands of RNA that were used.

In Joyce’s view, life’s system for recording and transmitting information must, in itself, possess enough information capacity to evolve entirely new processes – body armor, locomotion, or reproductive strategies, for example.

“We’re talking about more than just being ‘capable’ of undergoing Darwinian evolution,” he said. “It has to have – this is where it gets hard – some broad capacity to undergo Darwinian evolution. You need enough information to keep evolving: sensory systems, nervous systems, things like photosynthesis. If there’s enough complexity to invent a new biochemical function – that would do it for me.”

Still, his system might have borne at least a passing resemblance to some of the earliest forms of life. Research suggests that an “RNA” world might have preceded our DNA-dominated present. Although a more delicate molecule with far lower capacity to store information, RNA could have taken the first, halting steps toward life as we know it.

“There’s very good circumstantial evidence, based on the way biology unfolded, that RNA-based life preceded DNA,” Joyce said.

In the broad view, he said, momentum in astrobiology appears to be building. Advances in laboratory understanding of life’s components are beginning to converge with groundbreaking exploration of our solar system and deeper observation of planets around other stars.

“Many exciting things are happening,” he said. “There’s a focus on extrasolar planets, but what is happening on Mars is also incredible, with rovers, a helicopter, and a sample-return mission coming. And the next target will be the icy outer moons. It’s a really fun time in astrobiology.”

Avivagen makes voluntary assignment into bankruptcy under the bia.

Ottawa, Ontario--(Newsfile Corp. - April 24, 2024) - Avivagen Inc. (TSXV: VIV) ("Avivagen" or the "Company"), a life sciences corporation focused on developing and commercializing products for livestock, companion animal and human applications that safely enhance feed intake and support immune function, thereby supporting general health and performance, announced today that is has made a voluntary assignment in bankruptcy for the benefit of its creditors pursuant to section 49 of the Bankruptcy and Insolvency Act (Canada) ("BIA"). BDO Canada Limited has consented to act as Licensed Insolvency Trustee and will administer the estate and realize on the Company's assets in accordance with the BIA.

A notice of the bankruptcy and particulars of the first meeting of creditors will be sent to creditors by mail in the coming days.

Avivagen announced on May 18, 2023 that it had formed a Special Committee of the Board of Directors to explore strategic alternatives to maximize value for all stakeholders of the Company. The Special Committee explored many alternatives and engaged with many of the world's leading animal health and animal feed and nutrition companies, including Fortune 500 companies. Avivagen connected with existing suppliers, distributors, and new parties, leading to a number of reviews of the opportunity under confidentiality and with access to the Company's core information. One international conglomerate, specialized in the animal health industry, put forward a non-binding letter of intent ("LOI") that was signed and that would have seen a significant value ascribed to the animal health business of Avivagen. Following the completion of an agreed to exclusivity period and with significant diligence conducted, the other party notified Avivagen of a change at their company and that they could no longer complete the transaction. The LOI is no longer valid and other parties were contacted to engage in a strategic transaction, with conversations not producing an offer for the Company or its assets.

After a careful review of available options under the process to find strategic alternatives, and following thorough consultation with its legal and financial advisors, the Special Committee and the entire Board of Directors determined that the only option was to file a bankruptcy under the BIA. Despite the growing industry enthusiasm for antibiotic-free, sustainable food production and Avivagen's encouraging field and commercial results, including with customers in multiple countries, there are no viable opportunities to raise additional capital in the current market conditions and Avivagen was unable to identify a suitable solution available in the near term.

As a result of the contemplated transaction under LOI not being able to complete and insufficient resources, Avivagen has missed its regulatory requirements to file the following documents:

audited annual financial statements for the year ended October 31, 2023;

management's discussion and analysis relating to the audited annual financial statements for the year ended October 31, 2023; and

certification of the foregoing filings as required by National Instrument 52-109 Certification of Disclosure in Issuers' Annual and Interim Filings.

Trading in the common shares of the Company on the TSXV has been halted and it is anticipated that the trading thereof will continue to be halted permanently pending de-listing.

"The decision to initiate a bankruptcy of the Company has been the hardest decision in the entire journey of working for Avivagen – a journey of science and evidence to bring better health to animals and people alike," stated Kym Anthony, CEO of Avivagen Inc. "I regret the impact the restructuring and bankruptcy of our business will have on our valued stakeholders. This has been an incredibly difficult decision, but is the only one available to us now."

About OxC-beta™ Technology and OxC-beta™ Livestock Avivagen's OxC-beta™ technology is derived from Avivagen discoveries about β-carotene and other carotenoids, compounds that give certain fruits and vegetables their bright colours. Through support of immune function the technology provides a non-antibiotic means of promoting health and growth. OxC- beta™ Livestock is a proprietary product shown to be an effective and economic alternative to the antibiotics commonly added to livestock feeds. The product is currently available for sale in the United States, Mexico, Philippines, Taiwan, New Zealand, Thailand, Australia and Malaysia.

Avivagen's OxC-beta™ Livestock product is safe, effective and could fulfill the global mandate to remove all in-feed antibiotics as growth promoters. Numerous international livestock trials with poultry and swine using OxC-beta™ Livestock have proven that the product performs as well as, and, sometimes, in some aspects, better than in-feed antibiotics.

• Describe the field of biological science

The Study of Life

Biology is a natural science concerned with the study of life and living organisms. Modern biology is a vast and eclectic field composed of many specialized disciplines that study the structure, function, growth, distribution, evolution, or other features of living organisms. However, despite the broad scope of biology, there are certain general and unifying concepts that govern all study and research:

• the cell is the basic unit of life
• genes (consisting of DNA or RNA) are the basic unit of heredity
• evolution accounts for the unity and diversity seen among living organisms
• all organisms survive by consuming and transforming energy
• all organisms maintain a stable internal environment

Biological research indicates the first forms of life on Earth were microorganisms that existed for billions of years before the evolution of larger organisms. The mammals, birds, and flowers so familiar to us are all relatively recent, originating within the last 200 million years. Modern-appearing humans, Homo sapiens , are a relatively new species, having inhabited this planet for only the last 200,000 years (approximately).

History of Biological Science

Although modern biology is a relatively recent development, sciences related to and included within it have been studied since ancient times. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, Egypt, the Indian subcontinent, and China. However, the origins of modern biology and its approach to the study of nature are most often traced back to ancient Greece. (Biology is derived from the Greek word “bio” meaning “life” and the suffix “ology” meaning “study of.”)

Advances in microscopy also had a profound impact on biological thinking. In the early 19th century, a number of biologists pointed to the central importance of the cell and in 1838, Schleiden and Schwann began promoting the now universal ideas of the cell theory. Jean-Baptiste Lamarck was the first to present a coherent theory of evolution, although it was the British naturalist Charles Darwin who spread the theory of natural selection throughout the scientific community. In 1953, the discovery of the double helical structure of DNA marked the transition to the era of molecular genetics.

Science and Pseudoscience

Science is a process for learning about the natural world. Most scientific investigations involve the testing of potential answers to important research questions. For example, oncologists ( cancer doctors) are interested in finding out why some cancers respond well to chemotherapy while others are unaffected. Based on their growing knowledge of molecular biology, some doctors suspect a connection between a patient’s genetics and their response to chemotherapy. Many years of research have produced numerous scientific papers documenting the evidence for a connection between cancer, genetics, and treatment response. Once published, scientific information is available for anyone to read, learn from, or even question/dispute. This makes science an iterative, or cumulative, process, where previous research is used as the foundation for new research. Our current understanding of any issue in the sciences is the culmination of all previous work.

Pseudoscience is a belief presented as scientific although it is not a product of scientific investigation. Pseudoscience is often known as fringe or alternative science. It usually lacks the carefully-controlled and thoughtfully-interpreted experiments which provide the foundation of the natural sciences and which contribute to their advancement.

• Biology has evolved as a field of science since it was first studied in ancient civilizations, although modern biology is a relatively recent field.
• Science is a process that requires the testing of ideas using evidence gathered from the natural world. Science is iterative in nature and involves critical thinking, careful data collection, rigorous peer review, and the communication of results.
• Science also refers to the body of knowledge produced by scientific investigation.
• Pseudoscience is a belief presented as scientific although it is not a product of scientific investigation.
• pseudoscience : Any belief purported to be scientific or supported by science that is not a product of scientific investigation.
• science : A process for learning about the natural world that tests ideas using evidence gathered from nature.
• Biology : A natural science concerned with the study of life and living organisms.
