Microevolution
Paul Andersen defines microevolution as any change in the frequency of the allele pool. He then explains the five mechanisms of evolution; small sample size, non-random mating, mutations, gene flow and natural selection.

Population Genetics: When Darwin Met Mendel - Crash Course Biology
Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

Solving Hardy Weinberg Problems
Paul Andersen shows you how to solve simple Hardy-Weinberg problems. He starts with a brief description of a gene pool and shows you how the formula is derived. He then shows you how to solve a couple of sample problems.

Genetic Drift
Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern...
