Homo Erectus used tools, could do some counting and took tools from one location to another. There is also evidence that bands joined together for hunts. Neanderthal Man Fossils are abundant but they abruptly disappear. Lived together in small family units. Lived primarily off of small game like rabbits and waterfowl, but were also cannibals.
