How Pidgey "Proves" Darwinian Evolution

How Pidgey "Proves" Darwinian Evolution (subtitled Evolved?) is the 55th episode of Game Theory on The Game Theorists.

Description
''"Evolution" in the Pokemon games may not correspond to evolution as we know it in the real world, but that doesn't mean Pokemon games don't demonstrate Darwin's theory of descent with modification. In fact, evolution is VERY present throughout the Pokemon series...you just have to look for it.''
