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.

Remember how Darwin and Mendel lived around the same time, but everyone forgot about Mendel until 1900, and even then biologists saw Darwinism and Mendelism as two competing grand theories about how life works?
