Re: Evolution of Thought
The "bad design" issue actually strikes me as a serious problem for creationism, though its not discussed much. I'm pretty sure the female breast if the only "perfect" part of the human.
As far as human brain power, on avg we're about as smart as it takes to build shelter, figure out that crops can grow, harness animals, etc.--pretty much the basics required to maipulate our environment in various ways to reduce selection pressure. (There are, however, a few "geniuses" who can do things like create an alphabet if circumstances dictate.). Indeed, one might say that we evolved to the point where we were smart enough that it was no longer selectively advantageous to possess more intelligence.
