"Male and female baboons form platonic friendships, where sex is off the menu."

Take heart, beta males. It's not just our species:


BBC Earth News: Female baboons exploit chaperones


Having a caring friend around seems to greatly benefit the females and their infants, as both are harassed less by other baboons when in the company of their male pal.

But why the males choose to be platonic friends remains a mystery.

...

"So we really don't know what these guys got out of the friendship, other than maybe spending time with a mum and a new baby and having other females seeing this."

The suggestion here is that by chaperoning a female in a platonic relationship, a male might advertise his parental skills to other females, who then might consider him a worthy partner. But as yet, there's no evidence for this or any other reason why males become chaperones.

However, for the females, the benefits of having a chaperone are clear.

"We found direct evidence that friendships provided a social benefit to mothers and infants," says Nguyen.

"We found that mother-infant pairs who spent a lot of time with their male friends received a lot less harassment from other females in the group, and the infants cried a lot less too, than pairs who spent less time hanging out with their male friends."
