Descent and the genetic differences that are
heritable and passed on to the next generation;
Mutation, migration (gene flow), genetic drift, and natural selection
as mechanisms of change;
The importance of genetic variation;
The random nature of genetic drift and the
effects of a reduction in genetic variation;
How variation, differential reproduction, and heredity result in evolution
by natural selection; and
How different species can affect each other's evolution
through coevolution.
