Welcome! In this activity, you will visualize evolution at a simple level and develop your intuition for the process of genetic drift.

The three major forces of evolution are mutation, selection, and random genetic drift. These forces cause changes in genotypes and phenotypes over time, and also determine the amount and kind of variation seen in a population. This simulation focuses on drift (simulations of mutation and selection are under development).
