Evo-Ed: Integrative Cases in Evolution Education

Cases for Evolution Education

Colonizing the Beach

This game explores how selective predation can (1) effect fur color phenotype and (2) result in two different, independently evolving populations.

Instructions:

- 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?

Game Notes:
- This game was inspired by research being conducted by the Hopi Hoekstra lab at Harvard University: http://www.oeb.harvard.edu/faculty/hoekstra/
