Species A: The woodland vole (Microtus pinetorum)
Species B: The meadow vole (M. pennsylvanicus) —> relatively closely related to species a (for instance, in the same genus or family):
Species C: Macropus rufus —> less closely related to species a, but still in the same Class
These species shared ancestry from until Species C (the less related comparison species) split from the ancestor of Species A and Species B. Use your knowledge of evolutionary biology to reconstruct the following information about this Most Recent Common Ancestor (MRCA) of your three species:
1. When did it live? Why do you think this?
2. Where did it live? Why do you think this?
Think of three traits that differ between Species A and Species C. For each one, describe the probable condition of that trait in their Most Recent Common Ancestor. Very briefly explain why you think so.
3. Trait 1.
4. Trait 2.
5. Trait 3.
