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...

They're not likely to start barbecuing in the rainforest, but chimpanzees can understand the concept of cooking and are willing to postpone eating raw food, even carrying food some distance to cook it rather than eat immediately, scientists reported on Tuesday. The findings, based on nine experiments conducted at the Tchimpounga Sanctuary in Republic of Congo and published in Proceedings of the Royal Society B, suggest that chimps have all the brainpower needed to cook, including planning, causal understanding, and ability to postpone gratification. They do lack the ability to produce fire. But if they were given a source of...

Pro tip: Don’t fly your camera drone too close to chimpanzees. They might knock it out of the air using a stick. That’s what happened to one camera drone user over in the Netherlands while flying a drone in a zoo’s chimpanzee habitat. One of the chimps decided that “enough is enough”

<p>BOSTON – Charla Nash never served in the military. She was horribly disfigured, not in combat, but in a 2009 attack by a rampaging chimpanzee. The Pentagon, though, is watching her recovery closely.</p> <p>The U.S. military paid for Nash's full face transplant in 2011 and is underwriting her follow-up treatment at a combined cost estimated in the hundreds of thousands of dollars, in the hope that some of the things it learns can help young, seriously disfigured soldiers returning from war.</p>

New evidence underscores the theory of human origin that suggests humans most likely share a common ancestor with orangutans, according to research from the University of Pittsburgh and the Buffalo Museum of Science. Reporting in the June 18 edition of the Journal of Biogeography, the researchers reject as "problematic" the popular suggestion, based on DNA analysis, that humans are most closely related to chimpanzees, which they maintain is not supported by fossil evidence.

ALBANY, N.Y. -- A New York appeals court says a chimpanzee isn't entitled to the rights of a human and doesn't have to be freed by its owner. The three-judge Appellate Division panel was unanimous Thursday in denying "legal personhood" to Tommy, who lives alone in a cage in upstate Fulton County. A trial level court had previously denied the Nonhuman Rights Project's effort to have Tommy released. The group's lawyer, Steven Wise, told the appeals court in October that the chimp's living conditions are akin to a person in unlawful solitary confinement.

The exceptionally well-preserved fossil primate known as "Ida" is not a missing link as some have claimed, according to an analysis in the journal Nature. The research is the first independent assessment of the claims made in a scientific paper and a television documentary earlier this year. Dr Erik Seiffert says that Ida belonged to a group more closely linked to lemurs than to monkeys, apes or us. His team's conclusions come from an analysis of another fossil primate. The newly described animal - known as Afradapis longicristatus - lived some 37 million years ago in northern Egypt, during the...

Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes – gorillas and orangutans. They also found that humans evolved at a slower rate than apes. Appearing in the January 23, 2006 issue of the Proceedings of the National Academy of Sciences, biologist Soojin Yi reports that the rate of human and chimp molecular evolution – changes that occur over time at the genetic level – is much slower...

The brains of chimpanzees show a number of similarities to human brains, the results of two new studies suggest. Findings published in the December issue ofBehavioral Neuroscience indicate that the animals have differences between the right and left sides of their brains in much the same way that humans do. In addition, it appears that the neurological basis for handedness is not unique to our species. Hani D. Freeman of the Yerkes National Primate Research Center and his colleagues scanned the brains of 60 chimpanzees with magnetic resonance imaging (MRI) and measured two key regions of the brain's limbic system,...

By Clive Cookson, Science Editor Published: August 31 2005 18:46 | Last updated: August 31 2005 18:46 The first detailed genetic comparison between humans and chimpanzees shows that 96 per cent of the DNA sequence is identical in the two species. But there are significant differences, particularly in genes relating to sexual reproduction, brain development, immunity and the sense of smell. An international scientific consortium publishes the genome of the chimpanzee, the animal most closely related to homo sapiens on Thursday in the journal Nature. It is the fourth mammal to have its full genome sequenced, after the mouse, rat...

Despite decades of study, geneticists don't know what makes humans human. Language, long arms, and tree-climbing prowess aside, humans and our kissing cousins, chimpanzees, share practically all of our DNA. Genomic studies have suggested that the regulation of genes, rather than the genes themselves, set the two primate species apart. But genes are still an important part of the story, says Michele Cargill, a geneticist at Celera Diagnostics in Alameda, California. She and her colleagues found key differences between chimp and human genome coding sequences, differences that propelled human evolution and sometimes lead to genetic diseases. Genes for olfaction and...

Why the Y chromosome is a hotbed for evolution Mark Henderson, Science Editor The Y chromosome is often seen as the rotten corner of the human genome — a place of evolutionary decline that is slowly decaying and threatening the end of man. Reports of its imminent demise, however, have been exaggerated. Research has indicated that, far from stagnating, the male chromosome is a hotspot of evolution that is changing more quickly than any other part of humanity’s genetic code. In most mammals the sex of offspring is determined by X and Y chromosomes. Females have two Xs, males have...

A group of researchers from Korea and Japan has deciphered the Y chromosome of chimpanzees' genetic code, getting a step closer to solving the mysteries surrounding human evolution. It is well known that we share more than 98 percent of our DNA and almost all of our genes with the chimpanzee. Now the researchers have decoded more than half of the Y chromosomes, or 12.7 million base pairs, of man's closest living relative. "Because no genetic exchange occurs, the Y chromosome is important in explaining the evolution process," said Park Hong-seog, a senior researcher at the Korea Research Institute of...

Since the human-chimp split about 6 million years ago, chimpanzee genes can be said to have evolved more than human genes, a new study suggests. The results, detailed online this week in the Proceedings of the National Academy of Sciences, contradict the conventional wisdom that humans are the result of a high degree of genetic selection, evidenced by our relatively large brains, cognitive abilities and bi-pedalism. Jianzhi Zhang of the University of Michigan and his colleagues analyzed strings of DNA from nearly 14,000 protein-coding genes shared by chimps and humans. They looked for differences gene by gene and whether they...

Probable life appearance in anterior view of Ardipithecus ramidus ("Ardi"), ARA-VP 6/500.Photograph by: Handout, Illustrations 2009, J.H. Matternes An international team of scientists unveiled Thursday the results of 15 years of study of one of the oldest known human ancestors, Ardipithecus ramidus, which they say overturns much of what we know about human evolution. And surprisingly, it's also rewriting the story of our relation to gorillas and chimpanzees, our closest living relatives, and their development as well. Yohannes Haile-Selassie, one of the authors involved in the research and the man who discovered the first pieces of the most complete...
