Natural Selection & Sexual Selection: An Illustrated Introduction
Lesson created by Mya Thompson using
Video from LabofOrnithology YouTube Channel
How does evolution happen? Through a gradual process called selection. While we tend to think first about natural selection, the so called ‘survival of the fittest’, sexual selection can be just as strong an evolutionary force. This illustrated video explores how natural and sexual selection can shape the way animals look and act, sometimes transforming the drab into the magnificent.
