Colonizing the Beach
This game explores how selective predation can (1) effect fur color phenotype and (2) result in two different, independently evolving populations.
- Take a minute to observe the layout. There is one population of mice that inhabits a bicolor landscape; mice move around freely from the left side to the right siide (and vice versa). Mice die and are born at random intervals.
- Introduce a mutation. Do it two or three times to ensure the new phenotype doesn't randomly die out before the new it has a chance to reproduce.
- Introduce the predator. How does the predator effect the single population? How many populations are present after 2 or 3 minutes? Do mice still move freely across soil types or is their movement hindered by the predator?
