Although chimpanzees have been found in 21 countries in Africa, environmentalists still list them as endangered animals. Female chimpanzees mating is very mixed, so many males will think that they like to be dads, to prevent the killing of small chimpanzees.
Feeding and sex are the most primitive instincts of humans and their close relatives, chimpanzees. Homo sapiens scientists have been observing the relationship between food and sex in chimpanzees for years, but no consistent results have been obtained.
Female chimpanzees have an average reproductive interval of 5 to 6 years and are one of the longest-lived species in mammals. To improve reproduction, a female chimpanzee “copulates as many males as possible” and males compete with other potential mating competitors, says Melissa Emery Thompson, a primatologist at the University of New Mexico.
Some studies have found that male chimpanzees share catch or stolen grains with mating females. In 2007, a chimpanzee study in West Africa reported that if male chimpanzees could distribute their stolen papaya to females, females would mate more frequently with them. Kimberley Hockings, a postdoctoral student researcher at Brooks University in Oxford, argues that the male chimpanzee trades “forbidden fruit” for “food”.
But many studies do not support the theory that chimpanzees trade in food and sex, Emery Thompson said: “People think that’s because they think it’s interesting.” Her chimpanzee studies have shown that the problem of sex trade between chimpanzees is quite another matter.
When surrounded by male chimpanzees seeking sex, the female’s search for food will be affected, which will reduce their reproductive capacity, which is not conducive to the development of their population.
