LEIPZIG, Germany – In a finding that reinforces what males from every species already know to be true, a study by the Max Planck Institute reveals that female chimpanzees are more likely to mate with males that provide them with food.

Well, duh.

“We show that wild female chimpanzees copulate more frequently with those males that, over a period of 22 months, share meat with them,” Cristina Gomes, the author of the study, told The Local, a german news outlet in English.

The results, which were published in the journal PLoS One, “strongly suggest that wild chimpanzees exchange meat for sex, and do so on a long-term basis,” Gomes said, adding, “These findings are bound to have an impact on our current knowledge about relationships between men and women.” She believes the findings could shed light on human relationships in primitive “foraging” societies.

Gomes also said that she is interesting in continuing her research on primitive humans to see if theres also is a link between “reproductive success and good hunting skills.”
