Data refreshed Sep 29, 2026 Description Evolution is the central organizing principle of biology. Evolutionary theory has the power to explain biological phenomena over many scales and situations using the same set of relatively simple mechanisms. This course is an introduction to those mechanisms, how they drive evolutionary change in populations, how they lead to patterns of large-scale diversity among species, and how they help us understand the history of life on Earth.
