Natural Selection

Today, we will continue working on the objectives from last class. To get started, please select the best possible choice to describe why dark colored mice appeared on the dark rock.

I believe that the mice became dark furred over time because:
a) the light colored mice changed to match the rock
b) ash from exploding volcanoes turned the mice dark
c) dark mice selected to migrate from sandy areas to the dark rock
d) on the rock the dark mice were favorably selected to continue their life cycle

Defend your choice!

We will get together to discuss the choices. Try to convince everyone that your choice is the best.
