Look, I agree with you on that, but I don't think it's all species. I think ape species are more like that...tho thinking about it, there is a lot of that male-male competition, and female-female competition out there.

Is it just that, tho? I mean, haven't we evolved more than our biology? Hahah, are we so hopelessly slaved to the baser instincts?

I think it contributes, but I mean, how much? I don't know--you could be on to something!
