WebSO FAR, we have dealt chiefly with deterministic evolution, via natural selection.. TODAY, we explore the effects of finite population size and inbreeding on genetic variation, and show that this can lead to random evolutionary change (or "drift"). Mutation is, of course, a sort of random genetic change, but genetic drift can work much faster.
