"Shadow of Confidentiality!" – Evidence of a Lost Branch of Human Evolution

Post on 31 January 2019

Of Ancient Humanities

In August 2018, researchers found a bone bone researcher from a girl whose mother Neanderthal had and his father was Denisovan in a remote cave in Siberia. In the new study, researchers have estimated that this child has a fuel supply; lived between 79,100 and 118,100 years ago. Finding modern people today, scientists, share common ancestors with Denisovans and Neanderthals who had a lived about 600,000 years ago. Later – about 390,00 years ago – the separation of the Neanderthal and Denisovan streams.

Over the past ten years, Carl Zimmer's comments in the New York Times, the Denisova Cave "have given some of the most interesting fossils ever to give. To the eyes of nakedness, there is little to look – a few teeth, bone spots. But the fossils that include DNA have dropped ten thousands of years. This genetic material indicates that Denisovans was a branch Different types of human content, missing line. At any time in the past, Denisovans went out of sight – but they were not covered by today's people. Today , people in places such as East Asia and New Guinea still carry fragments of Denisovan DNA. "

The discovery in August in the cave in a remote river valley in Siberia was "sensitive" said Johannes Krause, who is studying an old DNA at the Max Planck Institute for Human History Science in Jena, Germany. "Now we have a different baby's two different hominin groups, which were found where members of the two groups were found. There are many things that happen in one cave for a while."

"Everyone said," These Denisovans are, we do not know what age they are, "said Katerina Douka, archaeologist at the Max Planck Institute for Human History Science in Germany. Over the past six years Eventually, Dr. Douka and other experts have been creating a history of the cave, which adds 103 sediments of sediments on the bottom of the cave, as well as 50 things found, including bones, carbon pieces and tools.

Max Planck scientists published this history in a newspaper paper published yesterday, which shows that people were live in the cave for up to 300,000 years, building some interesting ideas; Denisovans may have been able to have positive ideas, consistent with today's people.

The search results in August suggest that a & # 39; woman was just a teenager when she died more than 50,000 years ago, too young to have left a lot of marks in his world. But a piece of her bones, found in the cave in 2012, could be famous. Pretty old DNA inside the 2-centimeter fragment by showing its enjoyable ancestors: b & # 39; It was a fairy knoll just from two different species of old people, Neanderthal and the distinctive secretaries from Denisovan who had been split apart over 390,000 years ago.

Analyzes the feminine genome, Gretchen Vogel's sequences in Science, and # 39; shows that Neanderthal was her mother and Mrs. Denisovan, her father, the secret group of older people found in the same Siberia cave in 2011. It is the most powerful evidence of her; There are still many old people together and they had seeds.

Based on other ancient genomes, researchers have already decided that Denisovans, Neanderthals, and today's people have been involved in Ice Age in Europe and Asia. The genes of both types of ancient people are present in many people today. Other fossils found in the Siberia cave show that the three species have been live at different times.

Viviane Slon, a paleogenetic warden at the Max Planck Institute for Antropology Evolutionary in Leipzig, Germany, which made the old DNA analysis, says that when she saw the results, # 39; in the beginning. Only after the repetition of the test several times she and his colleagues Leipzig-Svante Pääbo, Fabrizio Mafessoni, and Benjamin Vernot-confirmed.

Given that only one of the two elderly species is found among its; First fossil ginomaes that emerged from the cave, Pääbo says, "when these groups met, they are very different."
