Where Did Kissing Come From?

Kissing is so commonplace that most people rarely think to stop and ask where humans picked up the habit in the first place. Where in humanity's evolutionary history did smooshing our faces together come to be regarded as a display of lust, care, friendship, and love? » 3/20/15 1:43pm 3/20/15 1:43pm

People Are Animals, Too

Tommy the chimpanzee got his day in court on October 8, 2014. He was unable to attend the hearing in 'person' – spending the day, like any other, in a cage in Gloversville, New York. But in an Albany courtroom, Steven Wise of the Nonhuman Rights Project argued that Tommy should be considered a person under New York… » 2/14/15 9:05am 2/14/15 9:05am

Chimps Change Their "Words" To Communicate Better With New Companions

Referred to as "referential calls," chimps use different grunts to identify objects. A new study provides the first evidence for vocal learning in non-humans, showing that chimps have the capacity for not just words — but also the ability to adapt to a new vernacular. » 2/06/15 12:40pm 2/06/15 12:40pm

Why An Appeals Court Was Wrong To Say This Chimp Isn't A Person

Yesterday, a New York appeals court rejected a lawsuit filed by the Nonhuman Rights Project seeking legal rights for Tommy, a 26-year-old chimp kept alone in a warehouse. Here's why the judges were wrong — and why that's actually good news in the struggle to recognize nonhuman animal personhood. » 12/05/14 9:20am 12/05/14 9:20am

Google Hiked Through Tanzania To Show You Where The Chimps Live

Today we're taking you deep into the forests of Tanzania, where Google has brought you images of Gombe National Park, home of Jane Goodall's chimpanzees. » 10/27/14 5:04pm 10/27/14 5:04pm

Scientists Watch How New Technologies Spread Among Wild Chimps

For the first time ever, scientists have witnessed the acquisition and spread of a new behavior — two new feeding methods — among wild chimpanzees. It's an 'extraordinarily rare' observation that points to the origins of social learning in both chimps and humans. » 10/01/14 12:40pm 10/01/14 12:40pm

Why Chimps Should Never Become Pets Or Performers

Chimps who are removed from their mothers early in life and raised by humans as pets or performers are more likely to develop behavioral and social problems, according to new research. » 9/23/14 7:00pm 9/23/14 7:00pm

Of all the world's animals, chimps and humans are some of the only to coordinate attacks on members of the same species. A new study concludes that, for chimpanzees, this kind of lethal aggression is "normal" and common. And by normal, the researchers mean the behavior stems from evolved tendencies, and not a response… » 9/17/14 6:00pm 9/17/14 6:00pm

Researchers Translate the Meaning of Over 60 Gestures Used by Chimps

In the first systematic study of a non-human primate language, scientists from St. Andrew's University have deciphered the meaning of 66 wild chimpanzee sign language gestures. Ranging from flirting requests to grooming instructions, the gestures may reveal how language evolves. » 7/04/14 2:00pm 7/04/14 2:00pm

Chimps Are Surprisingly Picky When It Comes To Music

If you ever run into a group of chimpanzees in a record store, you may find them congregating around the Indian classical section. But as for Western music, not so much. So suggests a new study that considered the musical tastes of our primate cousins. » 7/01/14 4:40pm 7/01/14 4:40pm

This is the most disturbing animal behavior David Attenborough has seen

Yesterday, naturalist Sir David Attenborough participated in a reddit AMA, answering questions from the reddit community. One thing that he revealed during the Q&A was the most upsetting thing he has witnessed in his career: chimpanzees hunting monkeys. » 1/09/14 11:40am 1/09/14 11:40am

Advocacy Group to Name Captive Chimp as Plaintiff in Historic Case

The Nonhuman Rights Project plans to file a case on behalf of its first animal client, an unnamed captive chimpanzee. Sometime in the next few months, it will file a writ of habeas corpus asking a state court judge to grant the chimp its liberty. It could go down as the first true step towards animal personhood. » 7/17/13 12:20pm 7/17/13 12:20pm

This ancient hominin could replace Lucy as humanity's closest…

Two million years ago in South Africa, part-human and part-ape-like individuals existed — and now we know what they looked like and how they behaved: They had a primitive, pigeon-toed gait, human-like front teeth, ate mostly veggies and spent a lot of time swinging in the trees. » 4/12/13 9:40am 4/12/13 9:40am

Chimps are better at teamwork than anyone realized

Chimpanzees sometimes work together to solve problems. But scientists haven't been sure whether chimps deliberately cooperate to reach a common goal, or accidentally do it by focusing on related tasks. Now, we have evidence that they are consciously working to form teams. This sheds light on the social behavior of… » 3/22/13 1:46pm 3/22/13 1:46pm

Watch as retired lab chimps see the sky for the very first time

In January we reported on the successful initiative by government scientists in the U.S. to end most research done on chimps. In all, about 450 chimps currently held in government research facilities will be retired from active duty and relocated to federal sanctuaries, including Chimp Haven in Louisiana. It's going… » 3/08/13 7:10am 3/08/13 7:10am

Ex-Lab Chimps Show Remarkable Improvement After Treatment With…

One can only imagine the psychological and emotional states of research chimpanzees who have been poked, prodded, and confined for a good portion of their lives. No doubt, once relieved from the burdens of medical testing, many chimpanzees have a difficult time adapting to "normal" life. But as a recent small-scale… » 2/19/13 3:39pm 2/19/13 3:39pm

The Reason Early Humans May Have Practiced Infant Cannibalism

Back during the Early Pleistocene era in Europe, there lived a now-extinct subspecies of humans called Homo antecessor. Archeological evidence indicates that this species practiced cannibalism — and that they preferred the meat of young children. The question now being asked by anthropologists is why. The answer, it… » 9/14/12 3:00pm 9/14/12 3:00pm

Chimps don't care if someone else gets robbed

Is justice a uniquely human concept? However you want to define it, the fact is we mete out punishment based on what one individual has done to another, even if we don't know either of those people. Yet this sort of group enforcement of laws seems pretty fundamental to our society — and it looks like it might be… » 8/30/12 10:30am 8/30/12 10:30am
