Male chimps exchange meat for sex

In the complex arena of chimpanzee sexual politics, ambitious males achieve congress — and lots of it — with a “prey for play” approach. Female chimps in a wild African community mated more frequently with males who, over a 22-month period, shared meat that had been acquired via monkey hunts, report graduate student Cristina Gomes and anthropologist Christophe Boesch, both of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
