It seems to me that chimps come by human traits very naturally. Like us they use and make tools (which when we discovered this, we changed the definition of "human" to exclude them), they kill for sport, they engage in organized warfare, they are omnivorous and at times they are cannibalistic.fgray1:Chimps are mean and nasty creatures. They will kill and eat anything. We give them human traits they don't have them naturally. They are CANNIBALS as well as thrill killers.
many animals kill just for the fun of it.
This is an exciting time in anthropology as there is now evidence that at one simultaneous point in time (as late as 12,000 years ago) there were 3 species of human on this planet. However this also has potentially distrubing implications as of those three species, the other two, both of which appear to have survived for a far longer period of time than us, became extinct shortly after our arrival on the scene. The possibile implication of that has an odd similarity to the biblical story of Cain and Able.
In my educated opinion, man seems to possess the flaw of believing in his own dominion and in his divine right to dominate other creatures and even dictate their very right to exist. And disturbingly throughout history man has frequently tried to extend this dominion to other men. Personally, I question the right of man to attempt to manage nature when most barely understand nature and fewer still truly understand themselves.
