    Here is some of what is posted on the page: Jan. 17 — The chimpanzee version of the AIDS virus appears to be extremely rare in wild chimps, which suggests the apes evolved a way to deal with the killer virus generations ago, researchers said on Thursday. The study also confirmed earlier theories that AIDS passed to humans from chimps in Central Africa, they said SCIENTISTS HAVE long known nonhuman primates carry their own version of the AIDS virus. But so far, it has been found only in captive chimpanzees. No one knows how prevalent or geographically or genetically diverse ...

    Mice and men share about 97.5 per cent of their working DNA, just one per cent less than chimps and humans. The new estimate is based on the comparison of mouse chromosome 16 with human DNA. Previous estimates had suggested mouse-human differences as high as 15 per cent. The new work suggests that neither genome has changed much since we shared a common ancestor 100 million years ago. "The differences are going to be few rather than many," says Richard Mural of Celera Genomics, the Maryland company that compared the mouse chromosome with human DNA. "Perhaps 100 million years separating...

    Though a New York judge ruled Thursday that the law still considers chimpanzees property, not people, a prominent thinker in the pro-life movement warned that attempts to raise animals to human status will continue.  Wesley J. Smith, co-director of the Discovery Institute's Center on Human Exceptionalism, said Friday, "We are gratified that a court refused to declare two chimpanzees 'persons.' That is right and proper. Chimps are animals, and the 'species barrier' separating the value of humans and animals, as some animal rights advocates put it, must never be breached."   "But make no mistake," Smith said. "Attempts to...

    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...

    A New York judge has granted two research chimps the writ of habeas corpus — a move that allows them to challenge their detention.The decision, says Science magazine, effectively recognizes chimps as legal persons, marking the first time in U.S. history that an animal has been given that right.The order, dated April 20, requires Stony Brook University to appear in court and provide a legally sufficient reason for keeping the two chimps, Hercules and Leo. A hearing is scheduled for May 6.The Nonhuman Rights Project (NhRP), the group that filed the case on behalf of the chimps, said in a...

    (Phys.org)—Members of a troop of chimpanzees living at a site called Fongoli in southeastern Senegal have been observed by scientists fashioning tree branches into spears and using them to hunt and kill bushbabies. The researchers, a combined team with members from the U.S. the U.K. and Germany have published their observations and findings in Royal Society Open Science. In their seven year study of the chimps living at the site, the researchers spotted chimpanzees breaking off tree branches, tearing off smaller branches and leaves, removing the weak tips and sometimes gnawing on the ends to sharpen them. The spears (which...

    Click here for video. King Kong's got nothing on her. A chimp being filmed by a drone for a television show based out of a zoo in the Netherlands decided she wasn't too keen on the invasion of privacy and swatted the drone from the sky, but the finished film was "special" nonetheless, according to the zoo. When a drone hovered over the chimpanzee exhibit at Burger's Zoo, while filming "Burgers' Zoo Natuurlijk" Friday, "the intelligent primates immediately discovered the spying little plane and right away armed themselves with long sticks against this inquisitive electronic intruder," the zoo's website said....

    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.

  • Primate fossil 'not an ancestor'

    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(human male genes so different from chimp's)

    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...
  • Scientists Find Evolution Clue in Chimp DNA

    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...

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.

    After 15 years of rumors, researchers made public fossils from a 4.4 million-year-old human forebear they say reveals that our ancestors were more modern than scholars had assumed, widening the evolutionary gulf separating humankind from apes and chimpanzees. The highlight of the extensive fossil trove was a female skeleton a million years older than the iconic bones of Lucy, the primitive female figure that has long symbolized humankind's beginnings. An international research team led by paleoanthropologist Tim White at the University of California, Berkeley, unveiled on Thursday remains from 36 males, females and young of an ancient prehuman species called...

    The first-ever chimpanzee fossils were recently discovered in an area previously thought to be unsuitable for chimps. Fossils from human ancestors were also found nearby. Although researchers have only found a few chimp teeth, the discovery could cause a shake-up in the theories of human evolution. “We know today if you go to western and central Africa that humans and chimps live in similar and neighboring environments,” said Nina Jablonski, an anthropologist at the California Academy of Sciences. “This is the first evidence in the fossil record that they coexisted in the same place in the past.” It had previously...
