The caveman, or homo neanderthalensis, lived in nuclear families during the Pleistocene Epoch in Eurasia around 200,000 to 300,000 years ago, taking shelter in caves and living a rudimentary existence. Fossilized remains suggest that most cavemen lived to be around 30 years of age, although some may have lived longer.
Cavemen used tools made from stone flakes, bones and antlers, and they learned to control fire. Neanderthals were carnivorous and sometimes cannibalistic, although recent research findings suggest that they ate vegetables, too. Theorists suggest that Neanderthals didn't go extinct, but were simply absorbed into the species or evolved to become modern man.
