Well, I won't disagree that humans are weaker than a bear, have worse vision than an eagle, breed more slowly than a rat, etc. But my point is that in some ways, we can compete against animals, and even are superior in a few areas besides our brains. Ofcourse, our brains are our greatest advantage but not our only one, and one might also argue that our brains are just another area for sexual competition that happen to have given us a few short-term advantages. 8,000 years isn't a long time, and that's pretty much the limit that we've been on top of the food chain. Brains aren't the perfect tool for survival anyhow. Einstein had what's considered to be one of the finest brains in history, and he paved the way for the atomic bomb.
