Decoding the cry of chimpanzees when

The chimpanzees often moan loudly when close to their partners in order to attract the attention of the nearby males. On the contrary, when there are other children prowling, they are silent to avoid hostility.

The function of screams during mating in female primates (including monkeys, gibbons, humans and chimpanzees) has been controversial over the years. A hypothesis was made that the children shouted to promote their sexual attraction to other potential partners. By promoting competition between males, females will be able to choose the strongest partner and create the best next generation quality.

But psychologist Simon Townsend and Klaus Zuberbuhler at the University of St. Andrews in Scotland found no evidence of competition between males and males when they observed chimp behavior in the Budongo forest in Uganda.

Instead, chimpanzees use a vocalization sound to seek the support of males against other ferocious members, especially females . They cried more when high-level males were close, but fell silent when horrible females appeared.

"The chimpanzees seem to pay more attention to having sex with many different males without letting other females know, instead of stimulating enmity between males ," Townsend said.

This tactic aims to minimize the risk of fighting between children that are very dangerous in nature.
