A big brain is NOT required for alertness and skill. A rabbit's brain is much smaller than a human's, but rabbits certainly seem to be alert and skillful at what they do. As for humans' heightened senses, this is incorrect as well. Human eyesight and smell are much poorer than our early ancestors'. No, my friend, these are NOT the reasons the human brain got bigger. It is much more likely it was evolutionary pressures to feed and breed cooperatively (to simplify a complex story).
