we where thought to be like African tribes non-permanent hunters and Gathers. I recommend an interesting show on the science channel I think it was called Ice world it explained prehistoric Humans very well. and not boring to watch real actors in it. it was about the Ice Age in Europe this also explains the argument creationist use about population since People where very rare at that time. its about 3 People that Travel all across Europe(on foot
) to find People the will except them. its VERY good
