MR T Posted about 1 year ago Are tensions, conflicts, and wars permanent part of the human condition? How can we avoid wars or mitigate the ravages of war? Guy called Robert Zapolsky was studying a nasty troop of baboons for 20 years until one day some of them ate contaminated meat and died. Turned out it was the big, testosterone fuelled males that were always fighting that had died. The social dynamic in the group completely changed, now 20 years on they still rarely fight and spend most of their time grooming each other.
