An anthropologist has described modern man as “the sorriest cohort of masculine Homo sapiens to ever walk the planet”, with even Arnold Schwarzenegger at his muscular peak no match for a Neanderthal woman in the arm-wrestling stakes. According to Peter McAllister, in Manthropology: the Science of Inadequate Modern Man, so completely wussy have we become that were Usain "Lightning" Bolt to go head-to-head with an ancient Australian aboriginal, it'd be silver medal position for the Jamaican sprinter. The prologue of McAllister's book warns blokes just how much of a humiliation they're in for, opening with: "If you're reading this then...

When it comes to love, we Homo sapiens are a peculiar breed: We thrill at the thought of torrid affairs while dreaming about the perfect someone with whom we can spend the rest of our lives. Some of this never-ending tug-of-war for our hearts is certainly cultural, but according to a new study it's also encoded in the finger bones of Neanderthals and the upright walking primate Australopithecus... In humans and primates, the ratio between the index and ring fingers is thought to be a telltale marker for how much of the androgen class of hormones -- and specifically, testosterone...

Anthropologists have built a "Frankenstein" Neanderthal skeleton, the first and only full-body reconstruction of the species. The result, announced today, is a shape no one expected. "It’s almost like making my own fossil discovery," said Gary Sawyer, one of the skeleton’s architects. Sawyer, an anthropologist at the American Natural History Museum in New York, and his colleague Blaine Maley of Washington University, pieced together the skeleton using bones mostly from an individual known as La Ferrassie 1. La Ferrassie 1 was missing its rib cage, pelvis, and a few other parts, so Sawyer and Maley had to scrounge around to...

An international team, led by researchers at the Department of Human Evolution, Max Planck Institute for Evolutionary Anthropology, in Leipzig, Germany, have extracted and sequenced protein from a Neanderthal from Shanidar Cave, Iraq dating to approximately 75,000 years old. It is rare to recover protein of this age, and remarkable to be able to determine the constituent amino acid sequence. This is the oldest fossil protein ever sequenced. Protein sequences may be used in a similar way to DNA, to provide information on the genetic relationships between extinct and living species. As ancient DNA rarely survives, this new method opens...

German and U.S. scientists have launched a project to reconstruct the Neanderthal genome, the Max-Planck Institute for Evolutionary Anthropology said Wednesday. The project, which involves isolating genetic fragments from fossils of the prehistoric beings who originally inhabited Europe, is being carried out at the Leipzig-based institute. [snip] "Firstly, we will learn a lot about the Neanderthals. Secondly, we will learn a lot about the uniqueness of human beings. And thirdly, it's simply cool," Rubin said. [snip]

Spanish researchers say they have found that a gene in modern humans that makes some people dislike a bitter chemical called phenylthiocarbamide, or PTC, was also present in Neanderthals hundreds of thousands of years ago... The scientists made the discovery after recovering and sequencing a fragment of the TAS2R38 gene taken from 48,000-year-old Neanderthal bones found at a site in El Sidron, in northern Spain, they said in a report released Wednesday by the Spanish National Research Council (CSIC)... Substances similar to PTC give a bitter taste to green vegetables such as Brussels sprouts, broccoli and cabbage as well...

Abstract: In Eurasia, the period between 40,000 and 30,000 BP saw the replacement of Neandertals by anatomically modern humans (AMH) during and after the Middle to Upper Paleolithic transition. The human fossil record for this period is very poorly defined with no overlap between Neandertals and AMH on the basis of direct dates. Four new 14C dates were obtained on the two adult Neandertals from Spy (Belgium). The results show that Neandertals survived to at least 36,000 BP in Belgium and that the Spy fossils may be associated to the Lincombian-Ranisian-Jerzmanowician, a transitional techno-complex defined in northwest Europe and recognized...

Key Concepts * Neandertals, our closest relatives, ruled Europe and western Asia for more than 200,000 years. But sometime after 28,000 years ago, they vanished. * Scientists have long debated what led to their disappearance. The latest extinction theories focus on climate change and subtle differences in behavior and biology that might have given modern humans an advantage over the Neandertals.

Newly analyzed remains suggest that a modern human killed a Neanderthal man in what is now Iraq between 50,000 and 75,000 years ago. The finding is scant but tantalizing evidence for a theory that modern humans helped to kill off the Neanderthals. The probable weapon of choice: A thrown spear. The evidence: A lethal wound on the remains of a Neanderthal skeleton.
-
DURHAM, N.C. -- The wound that ultimately killed a Neandertal man between 50,000 and 75,000 years was most likely caused by a thrown spear, the kind modern humans used but Neandertals did not, according to Duke University-led research. "What we've got is a rib injury, with any number of scenarios that could explain it," said Steven Churchill, an associate professor of evolutionary anthropology at Duke. "We're not suggesting there was a blitzkrieg, with modern humans marching across the land and executing the Neandertals. I want to say that loud and clear." But Churchill's analysis indicates the wound was from a...

Sometime between 28,000 and 30,000 years ago, an anatomically modern human in what is now France may have eaten a Neanderthal child and made a necklace out of its teeth, according to a new study that suggests Europe's first humans had a violent relationship with their muscular, big-headed hominid ancestors. The evidence, which includes teeth and a carefully butchered jawbone from a site called Les Rois in southwestern France, could represent the world's first known biological proof for direct contact between the two human groups.

Scientists in Leiden, in the Netherlands, have unveiled the specimen -- a fragment from the front of a skull belonging to a young adult male. Analysis of chemical "isotopes" in the 30,000-60,000-year-old fossil suggest a carnivorous diet, matching results from other Neanderthal specimens... The Neanderthal frontal bone is the first known "archaic" human specimen to have been recovered from the sea bed anywhere in the world. It was found among animal remains and stone artefacts dredged up 15km off the coast of the Netherlands in 2001. The fragment was spotted by Luc Anthonis, a private fossil collector from Belgium, in...

What most people know about the inheritance of eye color is that brown comes from a dominant gene (needing one copy only) and blue from a recessive gene (needing two copies). University of Queensland geneticist Rick Sturm suggests that the genetics are not so clear. "There is no single gene for eye color," he says, "but the biggest effect is the OCA2 gene." This gene, which controls the amount of melanin pigment produced, accounts for about 74 percent of the total variation in people's eye color. Sturm has recently shown that the OCA2 gene itself is influenced by other genetic...

A fossil discovery bears marks of butchering similar to those made when cutting up a deerOne of science's most puzzling mysteries - the disappearance of the Neanderthals - may have been solved. Modern humans ate them, says a leading fossil expert. The controversial suggestion follows publication of a study in the Journal of Anthropological Sciences about a Neanderthal jawbone apparently butchered by modern humans. Now the leader of the research team says he believes the flesh had been eaten by humans, while its teeth may have been used to make a necklace.

Dutch researcher Gerrit Dusseldorp analysed their daily forays for food to gain insights into the complex behaviour of the Neandertal. His analysis revealed that the hunting was very knowledge intensive. Although it is now clear that Neandertals were hunters and not scavengers, their exact hunting methods are still something of a mystery... His analysis of two archaeological sites revealed that Neandertals in warm forested areas preferred to hunt solitary game but that in colder, less forested areas they preferred to hunt the more difficult to capture herding animals... Rhinoceroses, bisons and even predators such as the brown bear were all...

Researchers working in Iceland said on Sunday they identified a genetic pattern that makes some Europeans more fertile. The genetic pattern, known as an inversion, is a stretch of the DNA code that runs backwards in people who carry it. Usually, such rearrangements of a chromosome are harmful to carriers. But this one causes carriers to have more children each generation -- giving them what is known as a selective advantage, the researchers reported. The finding, published in Monday's issue of the journal Nature Genetics, opens some interesting questions about human evolution, the team at Iceland's DeCODE Genetics said. "We...

Like many other researchers, paleoanthropologist Timothy Weaver of the University of California, Davis, thought the shift to this more complicated rotational birth predated the split between modern humans and Neandertals. That's because Neandertals, which lived until 30,000 years ago in Europe, also had big heads and, presumably, used the same evolutionary strategy to deliver their big-brained babies. But it has been difficult to test this idea. The only known female pelvis of a Neandertal, discovered in 1929 near Tabun, Israel, is fragmentary. Two earlier reconstructions of this partial pelvis suggested that Neandertals also had rotational birth, but the fossil is...

We tend to think of Neanderthals as one species of cavemen-like creatures, but now scientists say there were actually at least three different subgroups of Neanderthals. Using computer simulations to analyze DNA sequence fragments from 12 Neanderthal fossils, researchers found that the species can be separated into three, or maybe four, distinct genetic groups.

a new study suggests that the nicks seem to be the result of much more recent handiwork. Paleoanthropologist and archaeologist Jörg Orschiedt of the University of Hamburg in Germany reported yesterday at the annual meeting of the Paleoanthropology Society here that cut marks in the Krapina fossils he studied are randomly distributed and did not necessarily occur in spots that would permit de-fleshing (such as where muscles attach to bones). What's more, the scratches varied -- some were shallow and others deep. An alternative explanation to cannibalism dawned on him as he sifted through photos of the bones... he came...

First Draft of the Neandertal Genome Sequence Released by Jeffrey Tomkins, Ph.D.* The highly anticipated initial draft assembly of the Neandertal genome was announced at the Annual Meeting of the American Association for the Advancement of Science (AAAS) in the United States and at a European press conference.1 This genomic milestone involves approximately 3 billion bases of ancient human (Neandertal) DNA sequenced so far, which is the same amount of DNA contained in one set of human chromosomes or a single genome coverage. This is a major event in the booming scientific field referred to as “paleogenomics,” a discipline that...

Neanderthals are a step closer to walking on Earth again. Scientists have unravelled the genetic code of man's closest cousin using fragments of bone found across Europe. The blueprint could provide information on the Neanderthal's looks, intelligence, health and habits, as well as what makes us human. It also raises the intriguing possibility of bringing our ancient relatives, who died out around 30,000 years ago, back from the dead. Researcher Professor Jean-Jacques Hublin said: 'Studying the Neanderthals and studying the Neanderthal genome will tell us what makes modern humans really human, why we are alone, why we have these amazing...

The entire genome of a 38,000-year-old Neanderthal has been sequenced by a team of scientists in Germany. The group is already extracting DNA from other ancient Neanderthal bones and hopes that the genomes will allow an unprecedented comparison between modern humans and their closest evolutionary relative. The three-year project, which cost about ?5 million (US$6.4 million), was carried out at the Max Planck Institute for Evolutionary Anthropology in Leipzig. Project leader Svante Pääbo will announce the results of the preliminary genomic analysis at the American Association for the Advancement of Science annual meeting in Chicago, Illinois, which starts on 12...

Jan. 14, 2009 -- A trio of new studies on prehistoric weapons suggests Neanderthals made sophisticated weapons and tools -- possibly including the first sticky adhesive -- but they lacked the projectile weapons possessed by early humans. The missing technology, along with climate change and competition with arrow-shooting humans, may have contributed to the Neanderthals' eventual extinction. "While we are not suggesting that modern humans were directing projectile weapons against Neanderthals, it is certainly possible that at times they did so," Steven Churchill, co-author of one of the papers, told Discovery News.

The gene known as MC1R suggests the Neanderthals had fair skin and even freckles like redheads. After analysing the fossil bones found in a cave in north-west Spain, the experts concluded they had human blood group "O" and were genetically more likely to be fair skinned, perhaps even with freckles, have red or ginger hair and could talk... The report, published in BMC Evolutionary Biology, concludes that: "These results suggest the genetic change responsible for the O blood group in humans predates the human and Neanderthal divergence" but came "after humans separated from their common ancestor ... chimpanzees." ...One gene...

In a recently conducted study, a multidisciplinary French-American research team with expertise in archaeology, past climates, and ecology reported that Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change. The study, reported in the online, open-access journal PLoS ONE on December 24, figures in the ongoing debate on the reasons behind the eventual disappearance of Neanderthal populations, which occupied Europe prior to the arrival of human populations like us around 40,000 years ago. Led by Dr William E. Banks, the authors, who belong to the French Centre National de la Recherche...

For a species that went extinct more than 25,000 years ago, 2008 has been a hell of a year for Neanderthals.

Neanderthals may have died out because their bodies overheated as the Earth grew warmer, according to new research. Analysis of DNA obtained from Neanderthal remains has revealed key differences from modern humans that suggest their bodies produced excess heat. While in the cold climate of an ice age this would have provided the species with an advantage, as the earth warmed they would have been less able to cope. Ultimately this would have caused their extinction around 24,000 years ago. Scientists at Newcastle University have put forward the theory after examining a particular form of genetic material which was obtained...

In a gripping instance of Stone Age survival, Neandertals used a tarlike substance to fasten sharpened stones to handles as early as 70,000 years ago, a new study suggests. Stone points and sharpened flakes unearthed in Syria since 2000 contain the residue of bitumen -- a natural, adhesive substance -- on spots where the implements would have been secured to handles of some type, according to a team led by archaeologist Eric Boëda of University of Paris X, Nanterre. The process of attaching a tool to a handle is known as hafting. The Neandertals likely found the bitumen in nearby...

Harvard Archaeology Professor Noreen Tuross sought to rehabilitate the image of Neanderthals as meat-eating brutes last week, presenting evidence that, though they almost certainly ate red meat, Neanderthal diets also consisted of other foods -- like escargot. Evidence from Neanderthal bones collected from the Shanidar cave in Northern Iraq decades ago and analyzed recently by Tuross indicate that at least that particular Neanderthal was not a heavy carnivore. Neanderthals, she suggested, had a varied diet that included meat, but that was not solely or even largely made up of it. One possible alternative food was found in abundance in the...

It is widely accepted that Upper Paleolithic early modern humans spread westward across Europe about 42,000 years ago, variably displacing and absorbing Neandertal populations in the process. However, Middle Paleolithic, presumably Neandertal, assemblages persisted for another 8,000 years in Iberia. It has been unclear whether these late Middle Paleolithic Iberian assemblages were made by Neandertals, and what the nature of those humans might have been. New research... is based on a study of human fossils found during the past decade at the Sima de la Palomas, Murcia, Spain by Michael Walker, professor at Universidad de Murcia, and colleagues, and published...

The traditional answer has been that Neanderthals have a big nose because they have a big mouth and a wide jaw, useful for ripping apart tough food, says Nathan Holton, a paleoanthropologist at the University of Iowa. Why, then, do Neanderthals have faces that jut further out than humans? "They had them because earlier hominids had them," Houlton says. He laments the tendency of some anthropologists to "atomise the body", and explain each of its part as an exquisite adaptation to an environment. Selection for strong jaws and teeth has been a favourite explanation for other Neanderthal facial features, as...

The diet of prehistoric Neanderthals living in caves on the Rock of Gibraltar included seals and dolphins, showing once again that the hominids had skills rivaling those modern humans living then, according to a new study. The discovery of seal, dolphin and fish remains in the caves dating from 60,000 to 30,000 years ago provides the first evidence that Neanderthals ate sea mammals as well as land grub.

Most notably among the new studies is what researchers say is the first ever direct evidence that a woolly mammoth was brought down by Neanderthal weapons. Margherita Mussi and Paola Villa made the connection after studying a 60,000 to 40,000-year-old mammoth skeleton unearthed near Neanderthal stone tool artifacts at a site called Asolo in northeastern Italy. The discoveries are described in this month's Journal of Archaeological Science. Villa, a curator of paleontology at the University of Colorado Museum of Natural History, told Discovery News that other evidence suggests Neanderthals hunted the giant mammals, but not as directly. At the English...

Early stone tools developed by our species Homo sapiens were no more sophisticated than those used by our extinct relatives the Neanderthals. That is the conclusion of researchers who recreated and compared tools used by these ancient human groups. The findings cast doubt on suggestions that more advanced stone technologies gave modern humans a competitive edge over the Neanderthals.

At Nature, we often find that our most read, downloaded or listened to studies are those about our more ancient relatives, whether it's the hobbit of Flores or the oldest human ancestor, Toumai. Last week, a paper in the journal Cell uncovered the first completed sequence of the Neanderthal genome, and some fascinating insights into our evolutionary cousins. Expect more revelations from this project very soon. The demise of the Neanderthals is one of the great mysteries about the origin of our species. They were on a side branch in the human tree, co-existing with our direct ancestors for maybe...

Balkan caves, gorges were pre-Neanderthal haven Fri Jun 27, 2008 11:25am EDT By Ljilja Cvekic BELGRADE (Reuters Life!) - A fragment of a human jaw found in Serbia and believed to be up to 250,000 years old is helping anthropologists piece together the story of prehistoric human migration from Africa to Europe. "This is the earliest evidence we have of humans in the area," Canada's Winnipeg University anthropology professor Mirjana Roksandic told Reuters. The fragment of a lower jaw, complete with three teeth, was discovered in a small cave in the Sicevo gorge in south Serbia. "It is a pre-Neanderthal...

UK and Dutch research, published in the Journal of the American Heart Association, found a 5% cut in heart attacks for those with the key types. A UK geneticist said it could point to drugs which help many more people. What it does provide are...

What would it have been like to meet a Neandertal? Researchers have hypothesized answers for decades, seeking to put flesh on ancient bones. But fossils are silent on many traits, from hair and skin color to speech and personality. Personality will have to wait, but in a paper published online in Science this week (www.sciencemag.org/cgi/content/abstract/1147417), an international team announces that it has extracted a pigmentation gene, mc1r, from the bones of two Neandertals. The researchers conclude that at least some Neandertals had pale skin and red hair, similar to some of the Homo sapiens who today inhabit their European homeland....

Neandertals Had Big Mouths, Gaped WidelyMati Milstein in Tel Aviv, Israel for National Geographic NewsMay 2, 2008 Neandertals had big mouths that they were able to open unusually wide, new research has determined. A recent study found that a combination of facial structure, forward-positioned molars, and an unusually large gap between the vertical parts of the back of the jaw allowed Neandertals (also spelled Neanderthals) to gape widely. Modern humans and our direct ancestors don't have these traits, the researchers note. But the team was unable to measure exactly how far Neandertals could open their mouths. "This ability is connected...
