Study: Chimpanzees Have Evolved To Kill Each Other
sciencehabit writes A major new study of warfare in chimpanzees finds that lethal aggression can be evolutionarily beneficial in that species, rewarding the winners with food, mates, and the opportunity to pass along their genes. The findings run contrary to recent claims that chimps fight only if they are stressed by the impact of nearby human activity—and could help explain the origins of human conflict as well.
What a load of PC "humans are the only baddies in the world" bollocks.
Chimpanzees have a well documented history of intra-group hierarchical violence, violence against females and extra-group murdering raids. This is nothing new. Anthropologists have known this stuff for decades.
There is no such thing as "right" or "wrong" in nature and no delusions of morality can change that.
Here's the funny thing folks, humans are animals too!
As far as anyone can tell humans have a much greater ability to engage in complex planning: to make decisions based on sophisticated predictions of future consequences from an array of different actions. If you're hanging out with your friend in your living room and he has to go to the bathroom, most likely he'll make some initial assessments of his options, gather more information to increase the accuracy of his predictions: "Would you mind if I used your bathroom? Actually, better use the one off the master bedroom the one down the hall isn't flushing very well these days.", and then act on his predictions. On the other hand, if you have a horse over to hang out in your living room then pretty soon you'll be up to your ankles in horse manure.
We have all the same urges and evolutionary pressures,...
Except that with our complex planning it's actually easy to satisfy our evolutionary urges without needing to resort to violence. And we're also able to realize that evolution is a natural law like gravity. That having children in order to be evolutionarily successful is like throwing oneself down a flight of stairs in order to be gravitationally successful - that evolution isn't what should happen - it's what does happen.
...a brain big enough to develop ... violence ... to fill the hole that our self abstinence from murder has left.
No. People engage in violence when they're not able to find any other way to satisfy their (evolutionary) needs. Typically, the people who engage in violence are the ones with the brains that are too "small" - which isn't to say that smart people are never backed into a corner where violence is the only option. But most people who use violence do so because they are unable to make good predictions about all the possible actions and consequences available to them.
