"The Neanderthal genetic component in the [Tianyuan] early modern human was likely due to interbreeding after early modern humans had left Africa and overlapped with Neanderthals in the Middle East, before splitting into separate groups heading toward what are now Europe and East Asia," explained Fu. Fu and other scientists compared the DNA of the Tianyuan human with the genome of the now-extinct Neanderthal that the Max Planck Institute helped sequence and publish in 2010. The initial decoding of the Neanderthal genome and comparison with present-day populations around the world revealed that all contemporary humans outside of Africa carry a...

A scanty but varied ensemble of finds challenges the idea that Neandertal material culture was essentially static and did not include symbolic items. In this study we report on a fragmentary Miocene-Pliocene fossil marine shell, Aspa marginata, discovered in a Discoid Mousterian layer of the Fumane Cave, northern Italy, dated to at least 47.6-45.0 Cal ky BP. The shell was collected by Neandertals at a fossil exposure probably located more than 100 kms from the site. Microscopic analysis of the shell surface identifies clusters of striations on the inner lip. A dark red substance, trapped inside micropits produced by bioeroders,...

The FOXP2 gene is involved in speech and language (Lai et al. 2001)... Modern humans and Neanderthals share two changes in FOXP2 compared with the sequence in chimpanzees (Krause et al. 2007). Neanderthals may also have their own unique derived characteristics in the FOXP2 gene that were not tested for in this study... The researchers then tried to determine how the FOXP2 variant came to be found in both Neanderthals and modern humans... Though chimpanzees also have different blood groups, they are not the same as human blood types. While the mutation that causes the human B blood group arose...

[Note: headline edited slightly in order to fit] Origins of modern language are ten times older than thought and could date back half a million years, according to Dutch researchers It contradicts the popular idea that our modern language began with a sudden emergence of modernity presumably due to one or a few genetic mutations that gave rise to language The scientists claim that far from being slow brutes, Neanderthals' cognitive capacities and culture were comparable to ours Dutch researchers have claimed that our modern language can be traced back to stone age man - ten times older than previously...

The oldest example of grave flowers has been discovered in Israel. An ancient burial pit dating to nearly 14,000 years ago contained impressions from stems and flowers of aromatic plants such as mint and sage. The new find "is the oldest example of putting flowers and fresh plants in the grave before burying the dead," said study co-author Dani Nadel, an archaeologist at the University of Haifa in Israel. snip... Past evidence suggested that humans only started using flowers in graves more recently. (A 35,000-year-old Neanderthal burial site called Shanidar Cave in Iraq contained pollen, but subsequent research revealed that...

The study, led by Caleb Everett, associate professor of anthropology in the College of Arts and Sciences at the University of Miami, reveals that languages containing ejective consonants are spoken mainly in regions of high elevation. Ejectives are sounds produced with an intensive burst of air. The findings also indicate that as elevation increases, so does the likelihood of languages with ejectives. "Ejectives are produced by creating a pocket of air in the pharynx then compressing it." Everett says. "Since air pressure decreases with altitude and it takes less effort to compress less dense air, I speculate that it's easier...

Contrary to their hunting reputation, Stone Age Siberians killed mammoths only every few years when they needed tusks for toolmaking, a new study finds. People living between roughly 33,500 and 31,500 years ago hunted the animals mainly for ivory, say paleontologist Pavel Nikolskiy and archaeologist Vladimir Pitulko of the Russian Academy of Sciences. Hunting could not have driven mammoths to extinction, the researchers report June 5 in the Journal of Archaeological Science. On frigid tundra with few trees, mammoth tusks substituted for wood as a raw material for tools, they propose. Siberian people ate mammoth meat after hunts, but food...

Find Your Inner Neanderthal Published by ScottH under Ancestry http://blog.23andme.com/ancestry/find-your-inner-neanderthal/ They had bigger brains and muscles, but for some reason Neanderthals —thick boned humans who thrived for hundreds of thousands of years in Europe and parts of Asia— died out about 30,000 years ago, while we modern humans survived. Why we, Homo sapiens, flourished and our Homo neandertalensis cousins died out is an evolutionary mystery that biologist are trying to unravel. In the last few years, scientists have uncovered clues not just to what the lives of Neanderthals may have been like, but also clues that tell us more about...

The world's oldest known human tumor has been found in the rib bone of a Neanderthal who lived more than 120,000 years ago. The bone was evacuated from a site in Krapina, Croatia more than 100 years ago and has been found to have contracted the fibrous dysplasia tumor, a cancer which is common among modern-day humans. This discovery by David Frayer from the University of Kansas predates previous evidence of the tumor by more than 100,000 years. Before this discovery, the earliest bone tumor was seen in an Egyptian mummy around 2,000 years ago. David Frayer, professor of anthropology...

Freeze 'condemned Neanderthals' Small pockets of Neanderthals clung on in the south (Image: Gibraltar Museum) A sharp freeze could have dealt the killer blow that finished off our evolutionary cousins the Neanderthals, according to a new study. The ancient humans are thought to have died out in most parts of Europe by about 35,000 years ago. And now new data from their last known refuge in southern Iberia indicates the final population was probably beaten by a cold spell some 24,000 years ago. The research is reported by experts from the Gibraltar Museum and Spain. They say a climate downturn...

A baby Neanderthal who lived in what is now Belgium about 100,000 years ago started eating solid food at 7 months old, revealing a new aspect of the evolution of breast-feeding. The precision of this estimate is courtesy a new technique that uses elements in teeth to determine when breast-feeding started and stopped. Though researchers can't be sure the young Neanderthal's pattern was typical of its kind, such a breast-feeding pattern is not unlike that seen in many modern humans... Until now, however, no one had an effective way of looking at bones and reconstructing breast-feeding history. Past attempts had...

...People were already making finely worked bone needles 20,000 years ago, probably for embroidery as much as sewing animal skins, like the thousands of ivory beads and fox teeth that covered the bodies of a girl and a boy buried at Sunghir, Russia, around 28,000 years ago. This was some serious bling, representing years of accumulated work. And -- caveman stereotypes aside -- stone age clothes weren't just animal skins. We've known since the 1990s that people were weaving fabric back then, revealed by impressions in baked clay from the sites of Pavlov and Dolni Vestonice in the Czech Republic....

A 5,300-year-old man found sticking out of an Alpine glacier in 1991 possessed more genes in common with Neandertals than Europeans today do. The man’s Neandertal heritage is a preliminary sign that Stone Age interbreeding occurred more frequently than many scientists assume. Two researchers determined that the previously analyzed genome of Ötzi the Tyrolean Iceman (SN: 3/24/12, p. 5) included roughly 4 to 4.5 percent Neandertal genes. Modern Europeans’ genetic library includes an average of 2.5 percent Neandertal genes. Human groups that migrated into Europe after 5,000 years ago mated with continental natives and diluted traces of Neandertal genetic ancestry...

The results of an earlier round of sampling in El Castillo cave, published last June1, showed that the oldest of the paintings, a simple red spot, dates to at least 40,800 years ago, roughly when the first modern humans reached western Europe. Pike and his colleagues think that when they analyse the latest samples, the paintings may turn out to be older still, perhaps by thousands of years -- too old to have been made by modern humans. If so, the artists must have been Neanderthals, the brawny, archaic people who were already living in Europe... An early date for...

"Tools were made by a specific canon of Neanderthals living in Central Europe. These items have a cutting edge on both sides, they are bifacial" - said Dr. Wisniewski. Tools, including bifaces and asymmetric blades, are made of siliceous rocks, commonly called flint. According to head researcher, Neanderthals made their tools with holders made of antlers, wood or other materials. This is evidenced by the results of the microscopic analysis of similar items discovered in Germany. Among the flint, archaeologists also found fragments of coarse grained crystalline rock used as pestles - support tools in the manufacture of other tools....

Modern Y-Chromosome Variation Surpasses Archaic Humans by Jeffrey Tomkins, Ph.D. * The human Y-chromosome has been a sore point among secular scientists in recent years because of its many anti-evolutionary surprises. Adding to the Darwinian grief, is yet one more shocking Y-chromosome study that more clearly illustrates the boundaries of human genetic diversity. Much controversy has brewed during the past few years over the genomic sequences of what have been termed "archaic" humans. This so-called "ancient DNA" was extracted from bone fragments of "Neandertal" and "Denisovan" specimens and then sequenced, providing draft blue prints of these respective genomes.1, 2 While...

Ancient DNA recovered from a series of skeletons in central Germany up to 7500 years old has been used to reconstruct the first detailed genetic history of modern Europe. The study, published today in Nature Communications, reveals a dramatic series of events including major migrations from both Western Europe and Eurasia, and signs of an unexplained genetic turnover about 4000-5000 years ago. The research was performed at the University of Adelaide's Australian Centre for Ancient DNA (ACAD). Researchers used DNA extracted from bone and teeth samples from prehistoric human skeletons to sequence a group of maternal genetic lineages that are...

The archaeological deposits of the cave date back to between about 39,000 and 100,000 years ago to the Middle Paleolithic period. During the height of the ice age, the area still possessed a mild climate and supported a wide range of wildlife, including deer, wild boar, rabbits, elephants, weasels, foxes, wolves, leopards, bears, falcons, toads, vipers and tortoises. In the cave, the researchers found tools such as scrapers made of flint, quartz and seashells. The stone tools were all shaped, or knapped, in a way typical of Neanderthal artifacts. Now, the scientists reveal they discovered 14 specimens of child and...

The discovery of the structure of DNA and the subsequent developments in genetics and genomics have had a great impact on all of the biological sciences, including human evolution. Our ideas about human evolution 60 years ago came primarily from the fossil and archaeological records. These fields revealed that the last two million years were a dynamic period of our evolutionary history. The human lineage two million years ago was a population with ape-sized brains limited to sub-Saharan Africa. The human lineage expanded into Eurasia around 1.85 million years ago, and our brain size increased throughout the Pleistocene. Anatomically modern...
