Artificial selection occurs when humans choose traits that will be selected for or against. This has created the variety of domesticated animals and crops. He then describes the three main types of ecological natural selection: directional, stabilizing and diversifying. He finishes with a discussion on the importance of sex and the causes of sexual selection. | | | | | | | |  | | More videos. New Features. The official iPhone app is here.
