Ur abstract till den vetenskapliga artikeln Wild Chimpanzees Exchange Meat for Sex on a Long-Term Basis (Gomes, Boesch, 2009, PLoS ONE):

...we show that female wild chimpanzees copulate more frequently with those males who, over a period of 22 months, share meat with them. We excluded other alternative hypotheses to exchanging meat for sex, by statistically controlling for rank of the male, age, rank and gregariousness of the female, association patterns of each male-female dyad and meat begging frequency of each female. Although males were more likely to share meat with estrous than anestrous females given their proportional representation in hunting parties, the relationship between mating success and sharing meat remained significant after excluding from the analysis sharing episodes with estrous females. These results strongly suggest that wild chimpanzees exchange meat for sex, and do so on a long-term basis.
Ur New York Times långa artikel om dejtingsajten SeekingArrangement.com som specialiserar sig just på hannar som har råd att dela med sig, Keeping Up With Being Kept - Making it easy for 'Sugar Daddies' to connect with 'Sugar Babies':
The site now claims more than 300,000 registered members, far fewer than mainstream dating sites like Match.com, which has 1.5 million paying subscribers, but still a remarkable number. Sugar babies outnumber daddies 10 to 1, [the company ceo Brandon] Wade says, providing what one sugar daddy called 'the best fishing hole I ever fished in.'
