Males were fighting all the time
The best fighters got the best offspring
Aggressive genes spread all over the globe
Herds of wildmen lived in peace and war and peace for hundred thousands of years.
Civilisations grew out of each others, violent but effective.
In just a few millenniums the savage transformed to a cityman with gentle manners.
But the savage brain was almost the same...
The instinct of grabbing as much as possible was intact. They grab more and more.
Suddenly the earth got sick, it was fever....
The wildman strategy turned out to be a global treath.
From that day on there was just one way out; cooperation and moderateness.
Will the wildman succeed to follow this prescription; no one knows.
