Here is a simulator, from PhET, for determining scenarios of natural selection. I like the options that they give you. You can mutate the rabbit’s fur color, add food, introduce predators, or even dramatically change the environment from desert to arctic. You can also alter the rabbit’s genotype is order to produce the traits of long tails and long teeth. Students can view the results in the streaming analytics below.

As always, you need two rabbits before reproduction can occur.

Disclaimer: Bunnies typically refer to young rabbits.
