Around 600,000 years ago, humanity split in two. One group stayed in Africa, evolving into us. The other struck out overland, into Asia, then Europe, becoming Homo neanderthalensis - the Neanderthals. They weren't our ancestors, but a sister species, evolving in parallel.

Neandertal babies had chests shaped like short, deep barrels and spines that curved inward more than those of humans, a build that until now was known only for Neandertal adults, researchers say. Neandertals must have inherited those skeletal features rather than developing them as their bodies grew, says a team led by paleobiologist Daniel Garcia Martinez of the National Research Center on Human Evolution in Burgos, Spain. Stocky, big-brained hominids such as Neandertals needed chest cavities arranged in this way from birth to accommodate lungs large enough to meet their energy needs, the scientists contend October 7 in Science Advances....

Picturing how our species might appear in the far future often invites wild speculation over stand-out features such as height, brain size, and skin complexion. Yet subtle shifts in our anatomy today demonstrate how unpredictable evolution can be. Take something as mundane as an extra blood vessel in our arms, which going by current trends could be common place within just a few generations. Researchers from Flinders University and the University of Adelaide in Australia have noticed an artery that temporarily runs down the centre of our forearms while we're still in the womb isn't vanishing as often as it...

..............After drilling into the stalagmites and pulling out cylinders of rock, the team could see an obvious transition between two layers. On one side were old minerals that were part of the original stalagmites; on the other were newer layers that had been laid down after the fragments were broken off by the cave’s former users. By measuring uranium levels on either side of the divide, the team could accurately tell when each stalagmite had been snapped off for construction. Their date? 176,500 years ago, give or take a few millennia.

A growing number of ancient DNA studies on Neanderthals, Denisovans and Homo sapiens suggest intertwined evolutionary and population histories, including several admixture events between early modern and archaic humans. However, ancient nuclear and mtDNA sequences revealed phylogenetic discrepancies between the three groups that are hard to explain. For example, autosomal genomes show that Neanderthals and Denisovans are sister groups that split from modern humans more than 550,000 years ago. However, all but the earliest Neanderthal mtDNA samples are far more similar to those of modern humans than to those from Denisovans. These studies suggest that Neanderthals originally carried a Denisovan-like...

A milk-tooth found in the vicinity of "Riparo del Broion" on the Berici Hills in the Veneto region bears evidence of one of the last Neanderthals in Italy. This small canine tooth belonged to a child between 11 and 12 that had lived in that area around 48,000 years ago. This is the most recent Neanderthal finding in Northern Italy... The genetic analysis reveals that the owner of the tooth found in Veneto was a relative, on their mother's side, of Neanderthals that had lived in Belgium. This makes this site in Veneto a key-area for comprehending the gradual extinction...

Spy pics reveal ancient settlements August 03, 2006 06:51pm AUSTRALIAN researchers studying declassified spy satellite images have found widespread remains of ancient human settlements dating back 130,000 years in Syria. The photographs were taken by United States military surveillance satellites operating under the CIA and defence-led Corona program in the late 1960s. The team of researchers travelled to the Euphrates River Valley in April and June and searched sites they had painstakingly identified using the images, which were only declassified in the late 1990s. Group leader Mandy Mottram, a PhD student at the Australian National University's School of Archaeology and...

The two researchers investigated artefacts from one of the most important Neanderthal sites in Central Europe, the Sesselfelsgrotte cave in Lower Bavaria... 'The technical repertoire used to create Keilmesser is not only direct proof of the advanced planning skills of our extinct relatives, but also a strategical reaction to the restrictions imposed upon them by adverse natural conditions,' says Uthmeier, FAU professor for Early Prehistory and Archaeology of Prehistoric Hunters and Gatherers. What Uthmeier refers to as 'adverse natural conditions' are climate changes after the end of the last interglacial more than 100,000 years ago. Particularly severe cold phases during...

[Ghost] DNA from an unknown ancient ancestor of humans that once bred with Denisovans still exists among the genomes of people today, a study has revealed. The different branches of the human family tree have interbred and swapped genes -- a processes known as 'introgression' -- on numerous occasions... Experts from the US found that some three per cent of the Neanderthal genome came from interbreeding with another ancient human group 300,000 years ago... The researchers used the algorithm to look at genomes from two Neanderthals, a Denisovan and two African humans. Alongside finding that a small proportion of the...

The last 10 years have transformed the evidence concerning the early origins and evolution of Neanderthal populations. Genetic comparisons of Neanderthal and Denisovan ancient DNA suggest that the common ancestor of these populations separated from African ancestors of modern humans prior to 600,000 years ago, followed by a rapid differentiation in Eurasia. Later, additional episodes of gene flow brought genes into Neanderthal populations, including the mtDNA clade carried by all later Neanderthals. Yet, a number of western Eurasian fossil samples from the time between 600,000 and 100,000 years ago are difficult to accommodate within the category of "Neanderthals", including European...

Homo Neanderthaliensis did not become extinct because of changes in climate. At least, this did not happen to the several Neanderthals groups that lived in the western Mediterranean 42,000 years ago. A research group of the University of Bologna came to this conclusion after a detailed paleoclimatic reconstruction of the last ice age through the analysis of stalagmites sampled from some caves in Apulia, Italy. The researchers focused on the Murge karst plateau in Apulia, where Neanderthals and Homo Sapiens coexisted for at least 3,000 years, from approximately 45,000 to 42,000 years ago... Data extracted from the stalagmites showed that...

"After a decade of studying the cultural evidence yielded from the three seasons of archeological excavations at Kaldar Cave, the recent results show that a Paleolithic layer in the middle of this the cave is more than 63,000 years old," CHTN quoted Iranian archaeologist Behrouz Bazgir as saying on Sunday. Kaldar is a key archaeological site that provides evidence of the Middle to Upper Paleolithic transition in Iran. The cave is situated in the northern Khorramabad valley of Lorestan province and at an elevation of 1,290 m above sea level. It measures 16 meters long, 17 meters wide, and seven...

A stretch of DNA linked to Covid-19 was passed down from Neanderthals 60,000 years ago, according to a new study. Scientists don’t yet know why this particular segment increases the risk of severe illness from the coronavirus. But the new findings, which were posted online on Friday and have not yet been published in a scientific journal, show how some clues to modern health stem from ancient history. “This interbreeding effect that happened 60,000 years ago is still having an impact today,” said Joshua Akey, a geneticist at Princeton University who was not involved in the new study. This piece...

The University of Victoria paleoanthropologist Genevieve von Petzinger explains that a DNA test, which would reveal genetic mutations due to evolution, could help pinpoint the time period a painting was made and may help determine if the art was actually the handiwork of humans or Neanderthals — who lived about 130,000 to 40,000 years ago. "It would just be so fascinating to see the identity. The million dollar question is, did Neanderthals paint?" There is already some indication, according to von Petzinger, that this extinct species was, in fact, artistic. Von Petzinger said that a few years ago, some of...

One of these Neanderthal genomes was from an individual (Vindija 33) found in Vindija Cave in Croatia, whereas the other Neanderthal genome (Denisova 5 or the Altai Neanderthal) and the Denisovan genome (Denisova 3) both came from specimens discovered in Denisova Cave in the Altai Mountains... The researchers found that Chagyrskaya 8 lived 80,000 years ago, about 30,000 years after the Denisova 5 Neanderthal and 30,000 years before the Vindija 33 Neanderthal. They also found that the Chagyrskaya Neanderthal was a female and that she was more closely related to Vindija 33 and other Neanderthals in western Eurasia than to...

Ancient humans, Neanderthals and Denisovans were genetically closer than polar bears and brown bears, and so, like the bears, were able to easily produce healthy, fertile hybrids according to a study, led by the University of Oxford's School of Archaeology... The long history of matings between Neanderthals, humans, and Denisovans has only recently been demonstrated through the analysis of ancient genomes. The ability of mammalian species, including ancient humans, to produce fertile hybrid offspring has been hard to predict, and the relative fertility of the hybrids remains an open question. Some geneticists have even said that Neanderthals and humans were...

One in three women in Europe inherited the receptor for progesterone from Neandertals -- a gene variant associated with increased fertility, fewer bleedings during early pregnancy and fewer miscarriages. This is according to a study published in Molecular Biology and Evolution by researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden... Progesterone is a hormone that plays an important role in the menstrual cycle and in pregnancy. Analyses of biobank data from more than 450,000 participants -- among them 244,000 women -- show that almost one in three women in Europe have inherited...

Neanderthals selected rib bones from specific animals to make the lissoirs (French for 'smoothers'), which are bone tools that have been intentionally shaped and used on animal hides to make them softer and more water resistant, according to new research led by paleoanthropologists from the University of California, Davis. Scientists know that some Neanderthals produced bone tools. These include the discovery of five nearly identical fragments of lissoirs from two Paleolithic sites in southwest France: Pech-de-l'Azé I (Pech I) and Abri Peyrony. These specialized tools are often worn so smooth that it's impossible to tell which animal they came from...

In 2015, a research team led by archaeologists from the National Archaeological Institute of Bulgaria and the Max Planck Institute for Evolutionary Anthropology resumed work at Bacho Kiro Cave with the goals of clarifying the chronology and the biological nature of the makers of the artifacts. The researchers uncovered thousands of animal bones, stone and bone tools, beads and pendants and the remains of five human individuals... Using a state-of-the-art technology called Zooarchaeology by Mass Spectrometry (ZooMS), they identified human bone fragments and concluded that they were at least 45,000 years old -- a period coinciding with the arrival of...

Britons '200,000 years earlier than first thought' Man could have settled in Britain up to 200,000 years earlier than previously thought, according to new studies. Prehistorians had thought the predecessors of modern humans began living in Britain between 450,000 and 500,000 years ago. But recent discoveries in eastern and south western England suggest that is wrong, according to an article in the magazine New Scientist. Researchers working in conjunction with the Natural History Museum are basing their new theories on analysis of a flint axe and other tools found on the East Anglian coast and investigation of butchery marks ...
