Sometimes Nice Guys Finish First
In tribal societies, one might expect that the fiercest warriors get the most women and father the most children. But that’s not necessarily the case, says a new study of the brutal Waorani tribe of Ecuador. The most aggressive Wao warriors have about the same number of wives and children as milder-mannered men have, and their children are less likely to survive beyond the age of 15, largely due to an endless cycle of revenge killings. The Waorani are one of the most homicidal tribes ever studied. Located in a region just south of the Napo River, the place where the Andes Mountains meet the Amazon Basin, the tribe is preoccupied with revenge. Young Wao men are encouraged to develop a ferocious reputation early on, and before long they start raiding. The tribespeople constantly recount stories of these raids in gruesome detail, noting who was responsible and who needed to be avenged. Half of all Waos die violently.
