Its been a couple of years since I left school and Im sure someone doing A level biology could give you a much better answer but surely its fairly simple in that, the larger the brain the cleverer the person so the more intellegent people could set better traps to get more food ect so the ones with larger brains survived whereas the ones with smaller brains didnt?
