Evolution vs. Harry Potter

[mizaya.livejournal.com]

I'm curious about getting the opinions of all houses for this, so I thought I'd post this here.

I'm writing a paper for school about how the world of Harry Potter and Darwin's theory of evolution could co-mix. Sounds strange, I know, but the topic was to take Darwin's theory and apply it to one of your favourite artistic categories, which for me is obviously Harry Potter.

I'm having a really hard time starting out considering I'm not very well-versed in Darwinian theory, and I'm not entirely sure how to apply it to Harry Potter. Maybe how Muggles way back "evolved" into wizards? How certain "Muggle" creatures were able to evolve into the wizarding animals we know today?

Does anybody have any ideas for possible routes that I could take this?
