Anthropologists in Borneo observed a rare instance of a female and a male orangutan teaming up—to kill another female orangutan. This is the first observed time a female-female conflict in orangutans has turned lethal, and the way the it went down changes what we thought we knew about orangutan behavior.
Researchers in China have genetically engineered monkeys to exhibit autistic-like behaviors, including impaired social skills and increased anxiety. This research is poised to improve our understanding of brain disorders, but ethicists say the harm endured by these monkeys is simply not worth it.
Forget studies that show that we are lazy, fried cheese-fed, cubicle dwellers. Or, at least forget the “lazy” part. Out of all the primates, humans distinguish themselves by getting the least amount of sleep.
Are you in a public place? Look around. Can you tell whether any of the women you see are ovulating, just by looking at them? Neither can anybody else. But several small studies have suggested that men nevertheless find women’s faces more attractive when they’re most fertile. No one knows what signals the men are…
Although there is no definitive account of why we lost our body hair when every other primate is covered with the stuff, there are a handful of compelling theories that may explain our hairless condition.
There’s a new branch on the human family tree. Anthropologists say they’ve found a new human ancestor, who lived 3.5 million years ago, right beside Australopithecus afarensis on the plains of what is now Ethiopia.
It's hard to study intelligence in humans — our cultures are incredibly complex, and what counts as "smart" is defined as much by our societies as it is by our genes. So some researchers have turned to chimpanzees to understand what actually gives rise to intelligence in the brain.
Humans have a remarkable ability to see patterns where none exist. In the hot-hand phenomenon we perceive streaks of wins or losses where the data, in truth, are random. New research shows that monkeys are subject to the same bias, which might suggest that the bias is evolutionarily adaptive, and maybe even rational.
There has been a long tradition of employing animals in military operations. The latest example might be China's troop of macaque soldiers.
This little guy is so cute isn't he? He's a newly discovered slow loris—a kind of primate related to lemurs—and you can't help but want to give him a cuddle. Don't piss him off though, because he has a nasty toxic bite.
Keith Olwell and Elizabeth Kiehner had an epiphany last year. At a TED talk, the two New York advertising executives learned that captive monkeys understand money, and that when faced with economic games they will behave in similar ways to humans. So if they can cope with money, how would they respond to advertising?
