When Baboon Dads Stick Around, Their Daughters Live Longer
When papas of baboons stay, their daughters live longer
The new research shows that father -daughter relationships have a positive influence on the life of female baboons – when dads remain

The world of mammals is sorely lacking in good dads – at least according to human standards. In most species of mammals, males saddle the mother with their offspring while they continue galovants and tighten more. This is how male baboons generally work. But although these primat patriarchs do not treat young people or do not gather food (or provide no other essential care), a new study suggests that their presence has a beneficial impact.
In an article published Tuesday in Acts of the Royal Society B,, The researchers report that baboons who have solid relationships with their father – as measured by time that a father -daughter pair has spent preparing and living together – tends to overcome those who do not. Of the 216 women of the study (all of the Kenya Amboseli ecosystem, where the Amboseli Baboon research project has been underway since 1971), those who have a committed father enjoyed two to four years of life.
This does not necessarily show that the father-daughter link improves longevity; Young healthy women may already intended for a long life, are more likely to bind to their father. But the main author of the newspaper, Beth Archie, behavioral ecologist at the University of Notre Dame, says that his instinct is that the baboons “the dads are more important than they seem at first glance”.

An explanation of these results is that fathers create a “security zone” around their daughters, working to protect them in conflicts. Alternatively, fathers can serve as a gateway to the Babouin Society, allowing young women to establish links that will benefit them a lifetime. Whatever the papas of baboons, “it seems to make a difference,” explains Robert Seyfarth, primatologist and emeritus professor at the University of Pennsylvania, who was not involved in the study. The effect is probably similar to the wires, known as Archie, but they are more difficult to study because male baboons generally leave the group in which they were born when they reach maturity. The researchers tried to follow their lifespan by putting radio necklaces, she adds: “But the batteries died before men.”
Why are some baby baboons more involved in the lives of their daughters than others? The response can be linked to the promise practices of the species studied: in the population of Amboseli, both sexes have several coupling partners, so paternity is not always clear. As expected, researchers found that men spent more time preparing young women when they were convinced that they were In fact the father. (It is a call Male baboons can do realistically: the genitals of the females swell and become red during ovulation, so if a male man with one and repel the competitors until the sign of fertility disappears, it can be reasonably safe to play a role of off -sister. Mates, Archie says: “The best strategy is to invest more in your offspring.”
This “daddy’s mode”, as she calls it, is a powerful thing. Its importance in baboons resonates with our intuitions on the value of paternal care in our own species. Indeed, Archie thinks that these results of an evolutionary cousin can reveal something about the roots of human parenting. The big message, she says, is that “having a solid relationship with your parents is important to lead a long and healthy life. It seems to be a universal primate. ”
