adaptations and biological success. Wild chimpanzees also hunt in groups, and despite the
potential of inferring ancestral hominid adaptations, it remains unclear whether chimpanzee
hunting is a cooperative act. Here we show support for cooperative acquisition in wild
chimpanzees since hunters are more likely to receive meat than bystanders, independent of
begging effort. Engagement in prey searches and higher hunt participation independently
increase hunting success, suggesting that coordination may improve motivation in joint tasks.
We also
fi
nd higher levels of urinary oxytocin after hunts and prey searches compared with
controls. We conclude that chimpanzee hunting is cooperative, likely facilitated by behavioral
and neuroendocrine mechanisms of coordination and reward. If group hunting has shaped
humans

life history traits, perhaps similar pressures acted upon life history patterns in the
last common ancestor of human and chimpanzee. %J Communications Biology %V 1 %] 138 %I Nature Publishing Group %C London %@ 2041-1723
