001 - Natural Selection

Paul Andersen explains how natural selection is a major mechanism in evolution.  The video begins with a discussion of Charles Darwin and the details of natural selection.  The data of the peppered moth during the industrial revolution is used to show the process of adaptation.  Allele frequencies are calculated before and after the selection.  The adaptation of cichlids in African lakes is also included.
