In 2004, scientists observing a baboon troop found that the monkeys' culture could change dramatically, and enduringly, for the better. And all it took was massive amounts of death.
Children who don't know better might throw spitballs or pull hair to get another child's attention, and it turns out that certain monkeys do something similar. Female capuchin monkeys have been observed throwing rocks at males as a form of courtship.
Unlike all other primates, clawed New World Monkeys almost always give birth to twins. But why? It turns out these animals have a unique set of adaptations that make it possible — and could prove useful to humans as well.
Marmosets are fluffy, 8-inch-long monkeys native to South America. They are also very polite. New research shows that these little mammals carry on lengthy, back-and-forth discussions without interrupting one another. This is a conversation style adopted by only one other kind of primate: humans.
The use of stone tools is incredibly rare, so much so that it was once thought to be the exclusive domain of humans and our ancestors. Fellow apes like chimpanzees and baboons have since been proven to use stones as tools, but only a couple non-ape primates are known to do it. But now human encroachment might rob one…
No, we're not quite at the point where baboons can tackle calculus or trigonometry, but they do show an ability to count that's at least as good as that of a human child, as this video from the University of Rochester reveals.
Humans are known to change their behavior to fit in — particularly when interacting with an unfamiliar culture — but it wasn't known whether this fickleness was an evolved survival instinct or one of the quirky byproducts of our intelligence. Well, based on the behavior of male vervet monkeys, it appears the tendency…
As a group, primates aren't really known for their ability to create vocalizations, or sophisticated or complex sounds with their mouths. Yes, we humans have shown some talent in that area — what with the whole development of language and all that — but most apes and monkeys are unable to generate anything but the…
Sociological studies have found that middle managers tend to be more stressed than either their bosses or their underlings. That phenomenon might well be true of all primates, as macaques display heightened stress levels when they are in the middle of their social hierarchy.
While they're perhaps less likely to take up paragliding or get an ill-advised tattoo, it appears that other primates suffer from midlife crises just like Homo sapiens. A new study of chimps and orangutans found that they have a major dip in well-being during their middle years.
Life is tough for male and female macaques monkeys - especially when they're horny. Like many primate species, their sex life is right out there in the open for everyone to see, including alpha males and alpha females who do their darndest to prevent low ranking monkeys from having sex with each other. And indeed, as…
Bad news first: it looks like Rise of the Planet of the Apes recently kicked off in our reality. The good news? Our future ape overlords will implement a regime not unlike that of a no-budget 1980s comedy — think Porky's starring Doctor Zaius. As WJBF Augusta explains:
Granny Jane, a gibbon at England's Twycross Zoo, is probably at least a decade older than any of her counterparts in the wild. What's the secret to her longevity? According to her keepers, the secret is simply being chilled out.
We have identified well over a hundred different gestures used by chimpanzees, more than enough to reveal the primates use nonverbal communication much like we do. But it's what the chimps are saying with their hands that's truly fascinating.
Orangutans spend their lives swinging in trees and eating fruit. Neither of those things is all that surprising for small animals that don't need tons of energy — but it's distinctly weird for such large primates to live that way.
Parents often change their speech when talking to babies, simplifying their sentences and altering the words and noises they make to sound - and this is a technical term here - "more adorable." Turns out we're not the only ones.
As soon as orangutans go through puberty, they are pretty much expected to find a mate and start making babies. But as sexually frustrated high schoolers the world over will tell you, that's easier said than done.
We know that disparate chimp tribes separated by large areas have different behaviors and cultures, but what about those near to one another? It appears that neighboring chimpanzees do act differently in one key way: how they crack open nuts.
When a chimpanzee goes to sleep, it first has to build a "nest", which allows it to sleep safely up in the trees. Strangely, chimpanzees also build nests when sleeping on the ground, which might reveal a secret about human evolution.
The folks at the Bonobo Great Ape Trust Sanctuary of Des Moines, Iowa have a noble goal — to build their bonobos a teleoperated RoboBonobo so that the apes can interact with their environment using a mechanical avatar.
