Human apes are just one small twig on the vast tree of life. We are not the pinnacle of anything.

You know, there's this pervasive idea in biology that I think is wrong. It goes: we humans are at the pinnacle of the evolutionary tree, and as you get up that tree, brain size must get bigger. But a fly is just as evolved as a human. It's just evolved to a different niche.

Humans aren't high on the evolutionary scale...there is no evolutionary scale. We aren't the pinnacle of anything.
