I've always liked to think that Wesen came about naturally, not magically. I think that they are just different evolutionary branches of humans, some of which exhibit parallel evolutionary traits to other animals. Because they were hunted so mercilessly by the more populous humans, they evolved the ability to take on the visage of a human. That ability was possibly affected by the magic that is evident on the show. The abilities of a Grimm are genetic mutations that seperate them from humans, but only slightly.
