Are human apes more developed than a cockroach? Of course not. These 3 quotes explain why.

"There is no species that is “more developed” than another. In the end, the soupy mess of organisms that are alive today are all on the same level, having evolved to fit the specific ecological niches that they inhabit."

"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."
-- Jeremy Niven

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