From the smallest microorganism to the giant blue whale, every living thing is of interest to biologists, who study the basic principles of plant and animal life. Biologists use the scientific method, testing their ideas or hypotheses through experimentation, to investigate questions about the origin of life, its development, and the relationships between living things, as well as a creature’s anatomy and how it functions in its environment. Whether they’re working in a lab, out in the field, or at a university, biologists collect and analyze biological data, although the specifics of their research are as varied as the creatures in nature. For example, some biologists may work almost exclusively with computer models, while others may spend months collecting and studying specimens at sea. Many specialize in working with plants, animals, or the environment. Biologists need strong communication skills. Their work is often as much about interacting with people and institutions as it is focusing on DNA or anatomy. A career in biology generally requires a bachelor’s degree in the field. Many biologists attend graduate school to earn more advanced research positions or professorships.
