The Department of Ecology and Evolutionary Biology (EEB) is among six foundational science departments in Brown's Biology and Medicine division. The remaining five departments include: Molecular and Cell Biology and Biochemistry (MCB), Molecular Microbiology and Immunology (MMI), Molecular Pharmacology, Physiology, and Biotechnology (MPPB), Neuroscience (NS), and Pathology and Laboratory Medicine (PATH). These departments work together under the unified Program in Biology. Instead of providing specialized degrees for each department, the Program in Biology grants A.B. and Sc.B. degrees in Biology, along with interdisciplinary concentrations like Health and Human Biology and Applied Math-Biology. Complete concentration details are available on the Program in Biology website. Ecology and Evolutionary Biology covers the full spectrum of biological systems, from molecular and cellular levels to ecological communities and ecosystems, offering a comprehensive understanding of life sciences. Faculty and students research diverse areas including molecular evolution, plant and animal populations, ecosystem dynamics, animal behavior, functional morphology, paleoecology, physiology, phylogenetics, and genetics. These studies unite under a central theme: evolutionary principles. As noted by Theodosius Dobzhansky, a leading 20th-century scientist, "Nothing in biology makes sense except in the light of evolution." We emphasize that students pursuing ecology and evolutionary biology must develop a wide-ranging biological perspective to properly contextualize our field.
