Natural Selection 1: Let's Hunt!

This model allows students to hunt mice like a predator. They can compete with their peers to catch as many mice as possible. The competition yields selection pressure and demonstrates coloration evolution in the mouse population.

Natural Selection 2: Selective Pressure

This model allows students to test how the number of visual predators affects the coloration evolution in a mouse population. The patterns in the model directly lead to the NGSS core idea LS4.B Natural Selection.

Natural Selection 3: Differential Survival and Reproduction

This model allows students to examine individual mice’s color over time. They may also compare the survival and reproduction of mice with different colors in a specific environment.

Genetic Drift & Natural Selection

In this model, you will investigate the changes in allele and genotype frequencies affected only by genetic drift and by both genetic drift and natural selection.

Coevolution

This is a simulation modeling the process of coevolution.  Users may also observe different evolutionary patterns by adjusting the speed mutation extent in prey and/or predator populations.
