Female chimpanzees have a craving for sex with as multiple males as they can, but are awkwardly silent about it so as to increase their chances of attracting the alpha males as was revealed by a British university on Wednesday, 18th June.
However, they also found out that female chimpanzees make more copulation calls when the alpha males were closer so as to seduce them to mate. This tendency to have sex with multiple partners is believed to reduce the likelihood of alpha males killing baby chimpanzees as they will not which one they sired. This is a tendency seen in many animals, a notable example is lions that immediately kill the cubs of a newly conquered pride so as to raise their own offspring.
The scientists were able to deduce that female chimpanzees are usually quiet during mating so not to draw the attention of other top rival females which would endanger it and lessen its chances of having a top male sire its offspring. It would also lessen the probability for the top female chimps attacking them.
The scientists said competition among the wild females chimpanzees was quite stiff and therefore they make tactical sounds when attracting males so as to reduce the danger associated with the competition. And also to ensure that they also benefit from the alpha males.
However, there was no evidence that alpha males competed with each other for sex with the females when they made the mating calls. There was also no correlation between a females fertility and copulation calls.
