"The cave of the mystery!" – Evidence of the Lost Boundary of Human Evolution

Published January 31, 2019

Ancient human species

In August 2018, researchers discovered a bone fragment of a girl whose mother was a Neanderthal, and her father was Denisovan in a remote cave in Siberia. In a new study, researchers estimate that this hybrid child lived between 79,100 and 118,100 years. Contemporary humans, discovered by scientists, share a common ancestor with Denisovans and Neanderthals who lived about 600,000 years ago. Later – about 390.00 years ago – Neanderthals and Denisovans were divided.

Over the past decade, reports Carl Zimmer at the New York Times, Denis Cave "gave some of the most fascinating fossils ever found. Goliath's eye can not look much – several teeth, bits of bone. But fossils contain DNA that dates back tens of thousands of years. This genetic material shows that Denisovani were a separate branch of human evolution, a lost line. At some point in the distant past, the Denisans have disappeared – but not before crossing with modern people. Today, people in places like East Asia and New Guinea still carry fragments of Denis's DNA. "

Denis Cave

August's find in the cave in the isolated river valley in Siberia was "sensational," said Johannes Krause, who studied the ancient DNA at the Max Planck Institute for Humanities History in Yen, Germany. "Now we have a loving child of two different hominine groups, found where members of both groups were found. Much is happening in one cave through time. "

"Everyone said," These Denisovci, we have no idea how old they are, "said Katerina Douka, an archeologist from the Max Planck Institute for Humanities History in Germany. Over the past six years, Dr. Douka and other experts have created caves history 103 layer of sediment on the floor of the cave, as well as 50 objects found, including bones, pieces of coal and tools.

Max Planck's scientists have discovered this chronology in a couple of newspapers published yesterday showing that people have taken up the cave perhaps as many as 300,000 years ago, raising some intriguing indications that Denisovans could be sophisticated, in line with modern humans.

The results of research in August indicate that a woman might be just a teenager when she died more than 50,000 years ago, too young to have left a significant mark in her world. But a piece of one of its bones, discovered in the cave in 2012, can make it cunning. Enough ancient DNA was kept in a 2 centimeter fragment to reveal its stunning origins: it was a direct descendant of two different types of ancient people, Neanderthals and the mysterious Denisovana – the extinct hominine groups that separated each other more than 390,000 years ago.

New research reveals early "spiritual types" that crossed with people

The analysis of the female genome, continues Gretchen Vogel in Science, shows that her mother was a Neanderthal, and her father Denisovan, a mysterious group of ancient men discovered in the same Siberian cave in 2011. muttering together and having offspring.

Based on other ancient genomes, researchers have already concluded that Denisovci, Neanderthals and modern people crossed the ice age of Europe and Asia. The genes of both old human species today are present in many people. The other fossils found in the Siberian cave showed that all three species lived at different times.

Viviane Slon, a paleogenetic physicist from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who conducted an ancient DNA analysis, says that when she saw the results, her first reaction was disbelief. Only after the repetition of the experiment were convinced that she and her colleagues from Leipzig – Svante Pääbo, Fabrizio Mafessoni and Benjamin Vernot.

That direct offspring of the two ancient men found among the first few fossil genomes discovered by the caves suggests, Pääbo says, "When these groups met, they were actually freely intermingled with each other."
