3. Adaptive Evolution: Natural Selection
Edward P. Bass Professor of Ecology and Evolutionary Biology
This lecture elucidates the mechanisms of adaptive evolution, focusing on natural selection as the driving force. It examines the relationship between selection strength and evolutionary speed, distinguishing between directional, stabilizing, and disruptive selection outcomes.
Principles of Evolution, Ecology and Behavior (EEB 122)
Adaptive Evolution is driven by natural selection. Natural selection is not "survival of the fittest," but rather "reproduction of the fittest." Evolution can occur at many different speeds based on the strength of the selection driving it. These types of selection can result in directional, stabilizing, and disruptive outcomes. They can be driven by frequency-dependent selection and sexual selection, in addition to more standard types of selection.
