Angelina Jolie's lips are I think as much a product of collagen injections as much as any biological factor, evolutionary or otherwise.

Evolving six legs isn't really beneficial to any verterbrate I can think of, given you would virtually have to start from scratch physiologically. I think people are a strange compromise of sorts as far as evolution goes. We are the only biped mammal, and we had to evolve a lot of compromises to do that. There is a big debate out there in the paleoanthropology world about what environmental pressure or advantage was the prime factor in getting our long ago ancestors out of the trees and onto the ground, with two legs no less.

The fossil record records bipeds as long ago as ~3.6MYa, and basically that creature was a chimp that walked on two legs. It is quite entertaining to watch the creationists cook up explanations for all these things that according to them, weren't supposed to be there in the first place.
