The beautifully preserved remains of a 47-million-year-old, lemur-like creature have been unveiled in the US. The preservation is so good, it is possible to see the outline of its fur and even traces of its last meal. The fossil, nicknamed Ida, is claimed to be a "missing link" between today's higher primates - monkeys, apes and humans - and more distant relatives. But some independent experts, awaiting an opportunity to see the new fossil, are sceptical of the claim. And they have been critical of the hype surrounding the presentation of Ida. The fossil was launched amid great fanfare at...

Upright Walking Began 6 Million Years Ago Newswise — A shape comparison of the most complete fossil femur (thigh bone) of one of the earliest known pre-humans, or hominins, with the femora of living apes, modern humans and other fossils, indicates the earliest form of bipedalism occurred at least six million years ago and persisted for at least four million years. William Jungers, Ph.D., of Stony Brook University, and Brian Richmond, Ph.D., of George Washington University, say their finding indicates that the fossil belongs to very early human ancestors, and that upright walking is one of the first human characteristics...

Infectious Evolution: Ancient virus hit apes, not our ancestors, in the genesMarch 5 Bruce Bower A vicious virus infected ancestral chimpanzees and gorillas in Africa between 4 million and 3 million years ago. Not only did it kill a great many of these primates, but it also infiltrated the surviving animals' genomes, altering the course of evolution. That's the picture emerging from a new analysis of modern-primate DNA. Around 1.5 million years ago, this virus of the class called retroviruses also infected ancestors of modern baboons and macaques, two African monkeys, reports geneticist Evan E. Eichler of the University of...

The teeth, found in Germany, provoked one observer to suggest human history may need to be rewritten. Some experts, however, remain very skeptical. In a paper shared at the social networking site ResearchGate, Herbert Lutz and his team say they discovered “a new great ape with startling resemblances to African members of the hominin tribe.” The "plausible age” of the fossils — an upper left canine tooth and an upper right first molar — is 9.7 million years, they say. If confirmed, that would make the teeth around 6 million years older than fossils for the early-human, African ancestor Australopithecus...

A 9.7-million-year-old discovery has left a team of German scientists scratching their heads. The teeth seem to belong to a species only known to have appeared in Africa several million years later. A team of German archaeologists discovered a puzzling set of teeth in the former riverbed of the Rhine, the Museum of Natural History in Mainz announced on Wednesday. The teeth don't appear to belong to any species discovered in Europe or Asia. They most closely resemble those belonging to the early hominin skeletons of Lucy (Australopithecus afarensis) and Ardi (Ardipithecus ramidus), famously discovered in Ethiopia. But these new...

* This may be the most intact primate fossil skull ever discovered. * The fossil comes from a little-known period of primate evolutionary history. Source: Fred Spoor This is Alesi, the skull of the new extinct ape species Nyanzapithecus alesi (KNM-NP 59050). ================================================================================================================================ A group of scientists have found what may be the most intact fossilized primate skull ever discovered, and the find could shed light on the common evolutionary heritage shared by apes and humans. The lemon-sized skull was discovered in Kenya by an international team of researchers, and was dated to the middle of the Miocene era, a...

The study of the world’s oldest early primate skeleton has brought light to a pivotal event in primate and human evolution: that of the branch split that led to monkeys, apes and humans (anthropoids) on one side, and living tarsiers on the other. The fossil, that was unearthed from an ancient lake bed in central China’s Hubei Province, represents a previously unknown genus and species named Archicebus Achilles. The results of the research were published on 6 June 2013 in Nature. Oldest primate fossil rewrites evolutionary break in human lineage The fossil, which is 55 million years old and dates...

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,...

For education and discussion only. Not for commercial use. WASHINGTON - A nearly 13 million-year-old ape discovered in Spain is the last probable common ancestor to all living humans and great apes, a research team says in Friday's issue of Science magazine. A husband-and-wife team of fossil sleuths unearthed an animal with a body like an ape, fingers like a chimp and the upright posture of humans. The ancient ape bridges the gap between earlier, primitive animals and later, modern creatures. This newest ape species, Pierolapithecus catalaunicus, is so significant that it adds a new page to ancient human history....

Scientists have unearthed remains of a primate that could have been ancestral not only to humans but to all great apes, including chimps and gorillas. The partial skeleton of this 13-million-year-old "missing link" was found by palaeontologists working at a dig site near Barcelona in Spain. Details of the sensational discovery appear in Science magazine. The new specimen was probably male, a fruit-eater and was slightly smaller than a chimpanzee, researchers say. Palaeontologists were just getting started at the dig when a bulldozer churned up a tooth. Further investigation yielded one of the most complete ape skeletons known from...

After a decade of digging through the sand dunes of northern Chad, Michel Brunet found a skull 6-7 million years old. He named it Toumaï.Toumaï is thought to be the oldest fossil from a member of the human family. It's a dispatch from the time when humans and chimpanzee were going their separate evolutionary ways. A thrilling, but confusing dispatch1,2. Sahelanthropus tchadensis - Toumaï's scientific name - was probably one of many similar species living in Africa at that time. "There must have been a group of apes knocking around between 5 and 8 million years ago for which there's...
