Male chimpanzees are mama's boys! Bonobo's mothers find friends for their sons to help them become dads – but let their daughters arrange their own love lives
- Bonobo's mothers help their sons find a female partner to father their offspring
- However, they do not do the same for their daughters and leave it to them
- A mother increases the chance of their son to mate successfully three times
Bonobo's mothers help their sons to become fathers by recommending them to future partners.
Their strategies include placing them in the vicinity of ovulating women and physically preventing other men from competing with them.
This match-making increases the chance of the animal producing off-spring three times, but – despite this – the mothers often fail to help their daughters.
Scientists say this is because men occupy dominant positions over women in the bonobo community.

Bonobo's mothers help their sons to find suitable friends by introducing them to women. They succeed – they increase the chance that their sons become fathers by a factor of three (shares)
Head of the research group Dr. Martin Surbeck, a primatologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, observed wild bonobos in the Democratic Republic of Congo.
He then compared them with wild chimpanzees in Ivory Coast, Tanzania and Uganda.
Mothers from both communities helped their sons in the fight, but only the bonobos had a positive effect on their mating success.
& # 39; This is the first time that we have demonstrated the impact of the mother's presence on a very important male fitness character, what their fertility is, & # 39; he said.
& # 39; We were surprised to see that the mothers have such a strong, direct influence on the number of grandchildren they have.
& # 39; In Bonobo's social systems, the daughters disappear from the indigenous community and the sons remain. And for the few daughters who stay in the community, of which we don't have many examples, we don't see that they get help from their mothers.
While both Bonobo and chimpanzee mothers would argue for their sons in men's conflicts, female Bonobos tried their best to help their sons mating (stock)
HOW DO BONOBO MOTHERS HELP LAKE THEIR SONS?
They increase the likelihood of their sons becoming fathers by triple taking steps to ensure that they can mate with other women.
Their strategies include bringing their sons in close proximity to ovulating women and physically preventing other males from mating with other females.
The Bonobo species also protected their sons during copulation.
& # 39; These females have found a way to increase their reproductive success without having more offspring themselves. & # 39;
By doing this, the mothers can spread their genes without having more children themselves – at least that is Surbeck's theory.
They also seem to maximize their time on earth because bonobo mothers & # 39; have no substantial post-reproductive life & # 39 ;.
Bonobo & # 39; s are traditionally known as & # 39; pygymic chimpanzees & # 39; and are closely related to chimpanzees – with the two species being the only ones in the genus & # 39; Pan & # 39 ;.
The results of the observational study were published in Current biology.
