"adapted and evolved far above and beyond any others"

Simply not true. In fact, we are the last surviving representatives of what was once a tree with far more branches as there were quite a few species of humans. Take it back to the great apes, and there are only four extant genera left (humans, chimps inc.bonobos, gorillas, orang-utans); hardly an evolutionary success story.

We're not even old as a species, and in the time we've existed have managed to fuck the planet up with our arrogance and inability to curb our destructive instincts. Heck, even though we know we're doing it we still can't help ourselves, which is deeply pathetic. We're an evolutionary blip, as evolution is about equilibrium and when the equilibrium is upset, the big guys go first (as they are already doing). We're equilibrium-fuckers writ large, probably the only thing as a species we're good at.

So what is dominant? You can't single out a solitary species, but bacteria and fungi pretty much rule the roost, so show some respect and bow down to their utter superiority!
