Caption: Imoso, the highest-ranking male in the Kanyawara community of Kibale National Park, Uganda, grooms Outamba, a middle-aged female. Male chimpanzees at Kanyawara consistently prefer the oldest females in their community as mating partners, suggesting that the preference that human men exhibit for youthful women is a recent evolutionary phenomenon. For more information, see the Report by Muller et al. in the November 21 Current Biology.
