As population increased, a period of intense warfare lasted from 2,450 to 2,000 years ago, culminating in the victory of one town over all the others in the valley and the formation of the Zapotec state.

'It also shows that our species, when thrust into almost identical circumstances, behaves in almost identical ways.'"
