This field incorporates principles of biology with astronomy.īioarchaeologists are biologists who incorporate archaeological techniques to study skeletal remains and derive insights about how people lived in the past, according to George Mason University (opens in new tab).īioengineering is the application of engineering principles to biology and vice versa, according to the University of California Berkeley (opens in new tab). Here are a few examples:Īstrobiology is the study of the evolution of life in the universe, including the search for extraterrestrial life, according to NASA (opens in new tab). The multidisciplinary nature of biologyīiology is often researched in conjunction with other fields of study, including mathematics, engineering and the social sciences. For example, physiologists have studied how listening to music can cause physical changes (opens in new tab) in the human body, such as a slower or faster heart rate, according to the journal Psychological Health Effects of Musical Experiences (opens in new tab). Physiologists seek to understand biological processes, such as how a particular organ works, what its function is and how it's affected by outside stimuli. Physiology, which is applicable to any living organism, "deals with the life-supporting functions and processes of living organisms or their parts," according to Nature (opens in new tab). Physiology: The study of how living things work. For example, scientists have identified several genes and genetic mutations that influence human lifespan, as reported in a 2019 review published in the journal Nature Reviews Genetics (opens in new tab). Geneticists study how genes are passed down by parents to their offspring, and how they vary from person to person. For example, an ecologist may study how honeybee behavior is affected by humans living nearby. For example, pharmacology is a type of biochemistry research that focuses on studying how drugs interact with chemicals in the body, as described in a 2010 review in the journal Biochemistry.Įcology: The study of how organisms interact with their environment. There are numerous branches and subdisciplines of biology, but here is a short list of some of the more broad fields that fall under the umbrella of biology:īiochemistry: The study of the chemical processes that take place in or are related to living things, according to the Biochemical Society (opens in new tab). – Science and the scientific method: Definitions and examples For example, zoology is the study of animals, botany is the study of plants and microbiology is the study of microorganisms. On a high level, the different fields of biology can each be thought of as the study of one type of organism, according to " Blackie's Dictionary of Biology (opens in new tab)" (S Chand, 2014). During natural selection, organisms that have traits better-suited for their environment have higher rates of survival, and then pass those traits to their offspring.Īlthough there are only four unifying principles, biology covers a broad range of topics that are broken into many disciplines and subdisciplines. These traits result from random mutations in the organism's genes that are "selected" via a process called natural selection. Evolution is the principle that describes how all living things can change to have traits that enable them to survive better in their environments.Homeostasis is the principle that all living things maintain a state of balance that enables organisms to survive in their environment. ![]() Gene theory is the principle that all living things have DNA, molecules that code the structures and functions of cells and get passed to offspring.Cell theory is the principle that all living things are made of fundamental units called cells, and all cells come from preexisting cells. ![]() May 18-22 Week 7 Instructional Materials This is the last week new material will be assigned last day to turn in work is May 29th.
