An example of natural selection in Arizona Pocket Mice. See: http://bit.ly/1yBMMtx for more details regarding pocket mice and natural selection. The mutation slider sets the probability of having dark colored mice. A setting of 4 means there is a 4% chance of having dark mice babies. Hover over and click on the mice to eat them.
