    A gene from Denisovans makes people predisposed to mental health issues The gene was passed down to humans about 60,000 years ago in Asia Humans having sex with a now-extinct subspecies they met in Asia some 60,000 years ago could be the reason you have depression, a new study has claimed. Researchers discovered a gene variant linked to the crossbreeding of humans and Denisovans which they believe affects our mood. Those with the variant have lower levels of zinc in the body - a nutrient which studies increasingly show is associated with mood and happiness. Scientists said SLC30A9 is the...

    A molar discovered in a cave in Laos shows where the enigmatic Denisovans could have interbred with the ancestors of modern humans. A tooth found inside of a mountain cave in Laos has solved one of the biggest scientific mysteries of the Denisovans, a branch of ancient humans that disappeared roughly 50,000 years ago. Since 2010, when Denisovan teeth and finger bones were first discovered, DNA testing has revealed that the enigmatic hominins were among the ancestors of people alive today in Australia and the Pacific. But scientists didn’t understand how the Denisovans, whose scant remains had been found only...

    Using the latest scientific methods, Tom Higham and Katerina Douka from the University of Vienna want to solve a great mystery of human evolution: Why are we the only humans left? Higham and Douka were the first ones to find a first-generation offspring of two different types of human. They continuously publish new results in high impact journals, most recently in Science Advances.Our ancient cousins are more present in modern human DNA than we thought: Modern humans possess a small proportion of genes from archaic groups like Neanderthals. Every person having a European or Asian background has an average of...

    Deep in the forests of Laos, in a cave in the Annamite Mountains, lay a single child's tooth. That tooth – an unassuming molar - could be from a mysterious species of human we know little about, and of which few remains are known to exist. "Analyses of the internal structure of the molar in tandem with palaeoproteomic analyses of the enamel indicate that the tooth derives from a young, likely female, Homo individual," researchers write in a new study. The tooth, from the Tam Ngu Hao 2 cave, "most likely represents a Denisovan", the researchers say. Denisovans are an...

    HeritageDaily ^ | July 2021 | CNRS
    In a new study, scientists from the CNRS, Aix-Marseille University, and the French Blood Establishment (EFS) have examined the previously sequenced genomes of one Denisovan and three Neandertal females who lived 100,000 to 40,000 years ago, in order to identify their blood groups and consider what they may reveal about human’s evolutionary history. Of the 40-some known blood group systems, the team concentrated on the seven usually considered for blood transfusion purposes, the most common of which are the ABO (determining the A, B, AB, and O blood types) and Rh systems.The findings bolster previous hypotheses but also offer new...

    Truth is often stranger than fiction, and some people will never accept the truth no matter how much evidence you show them. In this article, I am going to discuss two brand new discoveries that are radically shaking up how scientists view human history. Many of the experts are having a really tough time explaining these new discoveries, because they seem to directly contradict long established narratives that have been taught as “truth” to young students for decades. Unfortunately, we live at a time when narratives have become more important than facts, and scientific authorities have shown that they will...

    “An interesting aspect of the Denisova 11 genome is that it allows us to learn things about two populations — the Neanderthals from the mother’s side, and the Denisovans from the father’s side,” said co-author Dr. Fabrizio Mafessoni, from the Department of Evolutionary Genetics at the Max Planck Institute for Evolutionary Anthropology.The researchers found that Denisova 11’s father, whose genome bears traces of Neanderthal ancestry, came from a population related to a later Denisovan found in the cave.The mother came from a population more closely related to Neanderthals who lived later in Europe than to an earlier Neanderthal found in...

    The woman may have been just a teenager when she died more than 50,000 years ago, too young to have left much of a mark on her world. But a piece of one of her bones, unearthed in a cave in Russia's Denisova valley in 2012, may make her famous. Enough ancient DNA lingered within the 2-centimeter fragment to reveal her startling ancestry: She was the direct offspring of two different species of ancient humans -- neither of them ours. An analysis of the woman's genome, reported in this week's issue of Nature, indicates her mother was Neanderthal and her...

    DNA extracted from bone fragments found in the cave show the girl was the offspring of a Neanderthal mother and a Denisovan father. The discovery, reported in Nature, gives a rare insight into the lives of our closest ancient human relatives. Neanderthals and Denisovans were humans like us, but belonged to different species. "We knew from previous studies that Neanderthals and Denisovans must have occasionally had children together," says Viviane Slon, researcher at the Max Planck Institute for Evolutionary Anthropology (MPI-EVA) in Leipzig, Germany. "But I never thought we would be so lucky as to find an actual offspring of...

      Is this stunning bracelet made by Paleolithic man for his favourite woman really 70,000 years old? By The Siberian Times reporter 02 August 2017 Startling new scientific evidence is to be reviewed by international experts which - if true - would transform our knowledge of the skills and sophistication of early man. A stunning discovery by team of Novosibirsk Institute of Archeology and Ethnography. Picture: Anatoly Derevyanko It is already known as the oldest stone bracelet in the world, believed to have been made not by ancient Homo sapiens but the extinct Denisovan species of early humans,  and previously  dated as being between 40,000 - 50,000 years old. The bracelet was found in 2008 in so-called Stratum 11 of world famous Denisova cave in the Altai region of Siberia. New findings suggest it could be 65,000 to 70,000 years old, long before ancient people were believed to capable of making such remarkable objects. Maksim Kozlikin, a researcher form the Institute of Archeology and Ethnography, Novosibirsk, indicated Australian specialists were among those to obtain exceptional results on the bracelet's age.  'Preliminary results have been received to date Stratum 11 where the bracelet was found to 65,000-to-70,000 years,' he said.  'So it all goes towards changing the dating of the find to more ancient.' It is understood that further checks were made, and the results were 'verified and verified again', according to one Russian report, citing scientists involved with the bracelet.  'Scientists are certain that multiple big headlines are coming up,' reported Novosibirsk TV Channel 10. This month experts from Russia will meet scientists from the University of Wollongong in Australia, and University of Oxford in the UK.  Professor Mikhail Shunkov, director of the Institute of Archeology and Ethnography, said: 'Our colleagues from Australia and Oxford are coming here in August, we will be discussing the dating then.' 'The bracelet is stunning - in bright sunlight it reflects the sun rays, at night by the fire it casts a deep shade of green'. Pictures: Anatoly Derevyanko, Konstantin Tynayev The bracelet was exhibited in Paris this year, carrying a label showing it to be 50,000 years old with the approval of scientists. 'Made 50,000 ago, for this kind of object and with the (known) level of technologies... this is (already) a world-level phenomenon,' said Dr Shunkov.  He said consensus on the age would be announced after the experts had discussed the dating, and that a major scientific journal study was expected. 'Until then, I will refrain saying anything,' he said, adding that some data was 'ambiguous' and required clarification. 'If or when we agree, we will have to prepare a publication first,' he said. Dr Shunkov and Denisova Cave in The Altai Mountains. Pictures: The Siberian Times  Efforts by The Siberian Times to reach the Australian scientists on their dating work were unsuccessful.  The bracelet is thought to have adorned a very important woman or child on only special occasions.  Scientists conclude it was made by our prehistoric human ancestors, the Denisovans, and shows them to have been far more advanced than ever realised. 'The bracelet is stunning - in bright sunlight it reflects the sun rays, at night by the fire it casts a deep shade of green,' said Professor Anatoly Derevyanko, the institute's former director.  'It is unlikely it was used as an everyday jewellery piece. I believe this beautiful and very fragile bracelet was worn only for some exceptional moments,' he said.  What made the discovery especially striking was that the manufacturing technology is more common to a much later period, such as the Neolithic era. Picture: Konstantin Tynayev The bracelet was found inside the famous Denisova Cave, in the Altai Mountains, which is renowned for its palaeontological finds dating back to the Denisovans, known as homo altaiensis, an extinct species of humans genetically distinct from Neanderthals and modern humans. Made of chlorite, the bracelet was found in the same layer as the remains of some of the prehistoric people and is thought to belong to them. What made the discovery especially striking was that the manufacturing technology is more common to a much later period, such as the Neolithic era.  Indeed, it is not clear yet how the Denisovans could have made the bracelet with the skills they had.  'Next to the hole on the outer surface of the bracelet can be seen clearly a limited polished zone of intensive contact with some soft organic material,' said Dr Derevyanko. Pictures: Anatoly Derevyanko Writing in the Novosibirsk magazine, Science First Hand, Dr Derevyanko said: 'Two fragments of the bracelet of a width of 2.7cm and a thickness of 0.9 cm were found. The estimated diameter of the find was 7cm.  'Near one of the cracks was a drilled hole with a diameter of about 0.8 cm. Studying them, scientists found out that the speed of rotation of the drill was rather high, fluctuations minimal, and that was there was applied drilling with an implement - technology that is common for more recent times. 'The ancient master was skilled in techniques previously considered not characteristic for the Paleolithic era, such as drilling with an implement, boring tool type rasp, grinding and polishing with a leather and skins of varying degrees of tanning.' Сonsensus on the age would be announced after the experts had discussed the dating, and that a major scientific journal study was expected. Pictures: Konstantin Tynayev  Chlorite was not found in the vicinity of the cave, and is thought to have come from a distance of at least 200km, showing how valued the material was at the time. Dr Derevyanko said the bracelet had suffered damage, including visible scratches and bumps although it looked as if some of the scratches had been sanded down. Experts also believe that the piece of jewellery had other adornments to make it more beautiful. 'Next to the hole on the outer surface of the bracelet can be seen clearly a limited polished zone of intensive contact with some soft organic material,' said Dr Derevyanko.  'Scientists have suggested that it was a leather strap with some charm, and this charm was rather heavy. 'The location of the polished section made it possible to identify the 'top' and 'bottom' of the bracelet and to establish that it was worn on the right hand.' Professor Anatoly Derevyanko, former director of Novosibirsk Institute of Archeology and Ethnography Redating the age of the bracelet would also mean other items found in the same layer were also older. A striking example is a Paleolithic needle now dated at 50,000 years. This is also seen as be made by the extinct Denisovans. Located some 150 km south of Barnaul, the the cave has immense palaeontological importance.  Over the years a number of remains have been found there, including some of extinct animals such as the woolly mammoth. In total evidence of 66 different types of mammals have been discovered inside, and 50 bird species. The most exciting discovery was the remains of the Denisovans, a species of early humans that dated back as early as 600,000 years ago and were different to both Neanderthals and modern man. In 2000 a tooth from a young adult was found in the cave and in 2008, when the bracelet was found, archaeologists discovered the finger bone of a juvenile Denisovan hominin, whom they dubbed the 'X woman'.  Further examination of the site found other artifacts dating as far back as 125,000 years. Dr Shunkov has suggested that the bracelet indicates the Denisovans - though now extinct - were more advanced than Homo sapiens and Neanderthals. 'In the same layer, where we found a Denisovan bone, we found interesting things; until then it was believed these the hallmark of the emergence of Homo sapiens,' he said.  'First of all, there were symbolic items, such as jewellery - including the stone bracelet as well as a ring, carved out of marble.' 'These finds were made using technological methods - boring stone, drilling with an implement, grinding - that are traditionally considered typical for a later time, and nowhere in the world they were used so early, in the paleolithic era. At first, we connected the finds with a progressive form of modern human, and now it turned out that this was fundamentally wrong.  'Obviously it was  Denisovans, who left these things.' The 7 centimetre (2 3/4 inch) needle was made and used by our long extinct Denisovan ancestors This indicated that 'the most progressive of the triad' (Homo sapiens, Homo Neanderthals and Denisovans) were Denisovans, who according to their genetic and morphological characters were much more archaic than Neanderthals and modern human.'  But could this modern-looking bracelet have been buried with older remains, perhaps dug into the cave floor in a later era to hide it? The experts considered this possibility but rejected it, saying they believe the layers were uncontaminated by human interference from a later period. The soil around the bracelet was also dated using oxygen isotopic analysis. The unique bracelet is now held by the Museum of History and Culture of the Peoples of Siberia and the Far East in Novosibirsk.  Irina Salnikova, head the museum, said of the bracelet: 'I love this find. The skills of its creator were perfect. Initially we thought that it was made by Neanderthals or modern humans, but it turned out that the master was Denisovan, at least in our opinion.'

    Scientists from the University of Oxford and the University of Manchester have used a new technique, "Zooarchaeology by Mass Spectrometry," or ZooMS, to identify more than 2,000 bone fragments recovered from Russia's Denisova Cave. ZooMS analyzes the collagen peptide sequences in bone, which can then be used to identify its species. Among the remains of mammoths, woolly rhino, wolf, and reindeer, the researchers found one Neanderthal bone. "When the ZooMS results showed that there was a human fingerprint among the bones I was extremely excited. ...The bone itself is not exceptional in any way and would otherwise be missed by...

    Previous analyses of the hominins from Sima de los Huesos in 2013 showed that their maternally inherited mitochondrial DNA was distantly related to Denisovans, extinct relatives of Neandertals in Asia. This was unexpected since their skeletal remains carry Neandertal-derived features. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have since worked on sequencing nuclear DNA from fossils from the cave, a challenging task as the extremely old DNA is degraded to very short fragments. The results now show that the Sima de los Huesos hominins were indeed early Neandertals. Neandertals may have acquired different mitochondrial genomes...

    Many recent studies have tried to understand when and where archaic hominins and our modern ancestors co-existed and interbred. Most of this research has been intent on cataloging Neanderthal gene sequences remaining in the genomes people of European or Asian descent. According to Vernot, "Different populations of people have slightly different levels of Neanderthal ancestry, which likely means that humans repeatedly ran into Neanderthals as they spread across Europe." Where the ancestors of modern humans might have had physical contact with Denisovans is debatable. The best guess, Akey said, is that Denisovans may have had a broad geographic range that...

    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...

    Neanderthal peoples' Asian cousins occupied the islands of our nearest neighbours and possibly Australia itself, scientists believe. Writing today in the journal Science, Adelaide University archaeologist Alan Cooper argues that the Denisovans – Neanderthal-like relatives of ancient humans – crossed Wallace’s Line, one of the world’s most formidable marine barriers, more than 100,000 years ago. Having achieved this feat, it would be “amazing” if they had not made what was then an easy crossing to Australia. “If you cross Wallace’s Line you’ve done all the hard work,” Professor Cooper told The Australian. The Denisovans were unknown before a finger bone...
