A study finds that male members of the Nyangatom population who participated in livestock raids in their youth may experience greater reproductive success in the long term than non-raiders. The high personal risk of engaging in warfare has led researchers to investigate the benefits that may drive raiding behavior. To determine whether raiding afforded a reproductive advantage, Luke Glowacki and Richard Wrangham traced the number of wives and children of 120 male members of the pastoralist Nyangatom people of Ethiopia and South Sudan.
