A new study finds humanity's closest living relatives will chew plants and apply makeshift poultices to wounds, and use leaves for a hygienic scrub. VIDEO AT LINK.............. Wild chimpanzees have been observed self-medicating their wounds with plants, providing medical aid to other chimps and even removing others from snares left by human hunters, new research suggests. The behaviors — which are documented in a new study published in the journal Frontiers in Evolution and Ecology on Wednesday — provide new clues about the origin of medical care in humans. The study combines historical data and about eight months of new...

All great mind reading begins with chocolate. That’s the basis for a classic experiment that tests whether children have something called theory of mind—the ability to attribute desires, intentions, and knowledge to others. When they see someone hide a chocolate bar in a box, then leave the room while a second person sneaks in and hides it elsewhere, they have to guess where the first person will look for the bar. If they guess “in the original box,” they pass the test, and show they understand what’s going on in the first person’s mind—even when it doesn’t match reality. For...

Dr Moya-Sola with colleagues discovered the fossil specimen of Pierolapithecus in Spain in 2002. They estimated that the hominid lived about 11.9 million years ago, arguing that it could be the last common ancestor of modern great apes: chimpanzees, orangutans, bonobos, gorillas and humans... the shape of the specimen’s pelvis indicates that Pierolapithecus lived near the beginning of the great ape evolution, after the lesser apes had started to develop separately but before the great ape species began to diversify... “The ilium – the largest bone in the pelvis – of the Pierolapithecus is wider than that of Proconsul nyanzae,...

With the recent SCOTUS decision, homosexuality is a hotter topic than ever before. It seems that everyone is talking about it right now. Well, in a recent Big Think video, Bill Nye “the Science Guy” was asked about homosexual behavior in an evolutionary worldview: “If the purpose of a species is to reproduce and survive how would it make sense evolutionarily for humans to have same-sex preferences? Are humans the only ones who practice homosexuality? And if this is so, does this mean that homosexuality is the product of humans personal whim as opposed to instinct?”Bill Nye basically answered this...

CHICAGO (AFP) - French fossil hunters have pinned down the age of Toumai, which they contend is the remains of the earliest human ever found, at between 6.8 and 7.2 million years old. The fossil was discovered in the Chadian desert in 2001 and an intense debate ensued over whether the nearly complete cranium, pieces of jawbone and teeth belonged to one of our earliest ancestors. Critics said that Toumai's cranium was too squashed to be that of a hominid -- it did not have the brain capacity that gives humans primacy -- and its small size indicated a creature...

Eagerly he collects wood from the ground, snaps the branches into small pieces and carefully balances them in a pile. Then, taking care not to burn himself, he gently strikes a match and gets ready for a fry-up. Like all red-blooded males, Kanzi loves messing around with a barbecue. But then, as these extraordinary pictures show, Kanzi is no man. He is a bonobo -pygmy chimpanzee -and his love of fire is challenging the way that we think about our closest relatives in the animal kingdom. For although bonobo apes and larger chimpanzees use twigs and leaves as tools, none...

Researchers have assembled the complete genome of the bonobo, an African ape that is one of humans' closest relatives. The achievement, reported Wednesday in the journal Nature, marks a milestone. Adding the bonobo genome to the already-sequenced human, chimpanzee, gorilla and orangutan genomes gives scientists a complete catalog of the DNA of all of the so-called great apes. That should help researchers better understand how humans evolved, scientists said. "There's a common ancestor that we and these apes were derived from. We want to know what that ancestor looked like," said Wes Warren, a geneticist at Washington University in St....

So much for the "hippy chimp". Bonobos, known for their peaceable ways and casual sex, have been caught in the act of cannibalism. An account of a group of wild bonobos consuming a dead infant, published last month, is the first report of cannibalism in these animals – making the species the last of the great apes to reveal a taste for the flesh of their own kind. The account comes from a group of primatologists led by Gottfried Hohmann of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. The team has studied bonobos in the wild at...

A detailed examination of the wrist bones of several primate species challenges the notion that humans evolved their two-legged upright walking style from a knuckle-walking ancestor. The same lines of evidence also suggest that knuckle-walking evolved at least two different times, making gorillas distinct from chimpanzees and bonobos. "We have the most robust data I've ever seen on this topic," said Daniel Schmitt, a Duke University associate professor of evolutionary anthropology. "This model should cause everyone to re-evaluate what they've said before." A report on the findings will appear online during the week of Aug. 10 in the research journal...

A type of chimpanzee known to use sex for greetings, reconciliations, and favors may not be all about peace, love, and understanding after all. A new study reveals that some bonobos—one of humankind's closest genetic relatives—hunt and eat other primates. Groups of the endangered chimpanzee subspecies were observed stalking, chasing, and killing monkeys they later consumed. /* snip */ "The second I read this, I thought: Oh good, finally!" said primatologist Elizabeth Lonsdorf of the Lincoln Park Zoo in Chicago. "Bonobos being so peaceful never sat well with me," said Lonsdorf, who was not involved with the study. "We see...

A type of chimpanzee known to use sex for greetings, reconciliations, and favors may not be all about peace, love, and understanding after all. A new study reveals that some bonobos—one of humankind's closest genetic relatives—hunt and eat other primates. Groups of the endangered chimpanzee subspecies were observed stalking, chasing, and killing monkeys they later consumed. Scientists have long known from stool samples that some bonobos eat rodents and small antelopes in their natural forest habitats in the Democratic Republic of Congo (DRC), but many researchers thought this was the extent of their hunting activities. Gottfried Hohmann and Martin Surbeck,...

Two penguins native to Antarctica met one spring day in 1998 in a tank at the Central Park Zoo in midtown Manhattan. They perched atop stones and took turns diving in and out of the clear water below. They entwined necks, called to each other and mated. They then built a nest together to prepare for an egg. But no egg was forthcoming: Roy and Silo were both male. Robert Gramzay, a keeper at the zoo, watched the chinstrap penguin pair roll a rock into their nest and sit on it, according to newspaper reports. Gramzay found an egg from...

MBIHE-MOKELE, Congo - Even as Congolese villagers devise novel ways to snare the fast-disappearing bonobo, scientists are racing to save the gentle "hippie chimp" from extinction. The bonobo, or pan paniscus, is closely related to man and known for resolving squabbles through sex rather than violence. It's also prized by some Congolese for its tasty meat. The wiry, wizened-faced chimps are being killed in treetop nests in Congo's vast rain forest, their only natural habitat in the world, by villagers who do not seem to know how fast their prey is disappearing. "Bonobos are an icon for peace and love,...

Pygmy chimpanzees known as "jungle hippies" for resolving conflict through sex rather than fighting are hurtling towards extinction faster than any other primate, experts said yesterday. Bonobos, gentle creatures found only in the remote war-torn forests of Congo, live in strictly matriarchal families and neither kill nor fight over territory. Bonobos chimpanzee is a close relative of man They also pair off for sex at the slightest hint of danger, stress or friction, earning them their hippy nicknames for "making love not war". They are among man's closest relatives and face the prospect of being the first great ape to...

Congo's "hippies of the forest" apes dying out fast By David Lewis KINSHASA, Sept 6 (Reuters) - Pygmy chimpanzees dubbed "hippies of the forest" for resolving conflicts through sex rather than violence are dying out faster than ever in post-war Democratic Republic of Congo, a conservationist said on Tuesday. Bonobos, the rarest of all the great apes, are being killed in large numbers by bands of gunmen two years after the vast central African country's most recent war officially ended. "In 1980, there were about 100,000 bonobos in Congo. In 1990 there were thought to be 10,000," Claudine Andre, founder...

LOOK at the world's worst trouble spots and you can't fail to notice they have one thing in common: tit-for-tat attacks between warring parties. Escalation of violence is incredibly destructive, yet we humans find it very difficult to break the vicious cycle. It seems we are not good at conflict resolution. Perhaps we could learn a lesson or two from the spotted hyena. Spotted hyenas are highly sociable. Like other animals that live in close-knit groups, they don't always get along. But spotted hyenas don't hold a grudge. Within about 5 minutes of a fight, the erstwhile combatants can often...

An elusive new species of great ape, known to locals as the "lion killer", may have been discovered in remote forests of the Congo. The creatures are far larger and more aggressive than normal chimpanzees and have provoked much debate among experts. Some believe that the lion killers are a previously unknown species and should join the other great apes: the chimp, bonobo, gorilla and orang utan. But others say they are unusually aggressive chimps with odd gorilla-like characteristics. Legends of lost apes of the Congo basin go back more than a century and inspired the 1980 novel Congo by...
