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

HOW IT WORKS
HOW IT WORKS
Mice move around in the simulation window. Each time when one or a few mice are hunted, the same number of mice will be randomly chosen from the rest of the population to reproduce offspring. At a 90% chance, the offspring's color will be the same as the parents'; at a 10% chance, the offspring's color will mutate to a different shade of brown.
