That marmosets can learn from other marmosets isn't all that surprising. Slightly more impressive is that they can learn from unfamiliar marmosets, who they haven't met before. But what's really amazing is they can learn from instructional videos.
Today marks the 22nd annual International Left-Handers Day. To celebrate, let's look at why only around one in ten people is left-handed. Why, pray tell, are lefties are so rare – or, said another way, why are most of us righties? It seems like a simple question, but it's actually one of the biggest mysteries in all…
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.
Scientists have discovered that two tiny, clawless, tree-living lemur species hibernate. Underground. For up to six months a year. Given that the furry animals are primates, the findings have exciting implications for possible human hibernation.
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.
It's not every day that scientists identify a brand new species of mammal. Rarer still is a confirmed discovery of a new species of primate — the mammalian order that encompasses humans, monkeys and apes. Now, for only the second time in 28 years, a new species of monkey has been identified in Africa.
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.
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.
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.
You may think that the only thing separating some of your friends from monkeys is their ability to at least read. Time for a rethink: new research shows that baboons are capable of learning how to tell the difference between real and fictional English words.
There are four genetically distinct chimpanzee populations, all found in two relatively small regions of Africa. And yet these populations, which are sometimes less than a mile apart, are more genetically diverse than humans that live on different continents.
Bonobos are famous as one of the relatively few species that has sex simply for pleasure. But just because our primate cousins aren't reproducing doesn't mean they're only having fun — as revealed by a new study of bonobo lesbian relationships.
At just five inches long, tarsiers are among the world's smallest primates. And yet they communicate much like humans, using a wide range of calls to communicate. That's why it's so weird that some tarsiers apparently stay completely silent.
Bonobos look like tame versions of chimpanzees. They're much less aggressive than chimps, their features are softer and smaller than their cousins, and they famously have sex for pleasure. Basically bonobos are domesticated... except humans had nothing to do with it.
Oxytocin is a hormone found to be crucial in the formation of loving bonds between mothers and babies, and it's thought to just generally makes people feel more sympathetic and connected to each other. That's definitely true of rhesus monkeys.
Until recently, scientists figured that the origins of human language could be found in our vocal cords. That seems reasonable enough, but the latest evidence suggests our hands are actually the source of language...and a bunch of hand-waving primates agree.
Our capacity for complex social interactions is a defining feature of humanity, but how did it evolve? It seems like it would have been a slow, gradual process, but a new statistical model suggests something very unusual happened 52 million years ago.
It seems like such a simple question, but it's actually one of the biggest mysteries in all of science. Is it because of how our brains are organized, how ancient humans gripped tools, or is it simple anti-lefty prejudice?
Primate Cinema: Apes as Family is an intriguing new art installation currently being shown in the UK. Half of it represents a human's attempt to make a movie specifically for chimps... while the other half shows how chimpanzees react to it.
