Biology WJEC BY2 Notes for 2.1 Evolution

Got given some notes at college, decided to edit them a tad, making them a bit easier to read and getting rid of the irrelevant stuff and highlighted the main points.

I found actually making these notes, (and the rest which are still to come) good revision, so if you don't know what to do with them, edit them yourself :) or just don't listen to me.. :)
