Right. Just that the predators not only kill the weak, they kill just everything they can catch. Canids are good killers, Felines are awesome! But the most terrific killer that has ever evolved is called: homo sapiens.
That's why we're sitting here.
Yep. We're some relatively clever mammals running around on two legs. That's about it.
Oh, I almost forgot, this strange evolutionary concept of cleverness led to an unprescedented higher order phenomenon: culture. Within our culture we define and appraise ourselves, using mechanisms like religion, philosophy, money.
I think, that is quite a differentiator. But only in our own minds of course, evolution doesn't care at all if we blow up mankind in an atomic hell fire by next Friday.
