The wise men of the establishment are again telling us that hopes for lasting peace are a delusion. They declare that human nature makes it impossible, that war is built into our genes. They point to research by evolutionary biologists that indicates our closest genetic relatives, the chimpanzees, make war. Therefore war must be part of our heredity.
"We've always had wars," they claim. "Humans are a warring species. Without a military to defend us, someone will always try to conquer us." These assumptions have become axioms of our culture. They generate despair but also a certain comfort because they relieve us of the responsibility to change.
It's true that in certain situations chimpanzees do raid neighboring colonies and kill other chimps. Those studies on killer apes got enormous publicity because they implied that war is hardwired into human nature. Most scientists didn't draw those conclusions from the evidence, but the establishment media kept reinforcing that message.
Further research, however, led to a key discovery: The chimps who invaded their neighbors were suffering from shrinking territory and food sources. They were struggling for survival. Groups with adequate resources didn't raid other colonies. The aggression wasn't a behavioral constant but was caused by the stress they were under. Their genes gave them the capacity for violence, but the stress factor had to be there to trigger it into combat.
