Sometimes cooperation trumps competition—even among wild monkeys. That's what scientists say certain species seem to know despite the competitive evolutionary mandate of "survival of the fittest."
In a five-year study of Gelada monkeys, researchers from three universities have noted that alpha males who allow some subordinate males into their group and even at times form alliances with them suffer fewer takeover attempts. Though Alphas who share their power and cooperate also have to split their genetic monopoly by allowing subordinates to mate with the group’s females, the sex-security tradeoff usually benefits the leader in the long run, according to researchers.
