Fossil evidence suggests that even australopithecines used spears and clubs, which are much more effective weapons than teeth. Darwin's dogs have well protected heads because they have to use them as weapons - no cat-claws, and no man-thumbs. But one man with a spear can kill a lion or a bear, keeping his fragile head far away from danger. So our heads have evolved to accomodate tracking and cooperation skills, rather than pointy teeth. Actually, as hunters, humans are considerably better adapted than dogs and wolves. We have much better stamina than any other animal - healthy humans can happily dog-trot better than thirty miles a day, every day. This is mainly due to humans being the sweatiest animals; if you ever need to hunt your dinner, you can just trot after it until it drops of heat prostration. You can do this even if you have a taste for dogmeat! Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=4532
