Neanderthals were the most complex people before Man showed up. The 2 may look similar, but there are differences. First, Neanderthals had more robust bones, suggesting that they hunted gigantic prey more often. Neanderthal bones have been found with fractures that are similar to the fractures left on the bones of rodeo riders. Of course, Neanderthals didn't do rodeos. But they were tough and they could handle it. Another feature is that the nasal passages are bigger. This suggests that Neanderthals had big noses to warm the air they breathed, like a Saiga Antelope. They also didn't have grooves on their canine teeth. So their lives were not so easy. But Geico is so easy a caveman can do it.
