evolution:

something went a little bit wrong, and the babies are a little bit different than what they should be.
if they're lucky, that little bit wrong means they get to have more babies than the rest of their species.
over generations, the side that went a little bit wrong gradually becomes more and more prevalent, compared to the side that stayed the same.
sometimes, both can survive. other times, the new population continues to grow, as the old continues to dwindle.

sometimes, they're not lucky and they have fewer babies that the rest of their species, and the mutation dies out.
and sometimes, they new side is unlucky and dies to something completely random even if they would have otherwise been able to replace their cousins.
