In August 2018, the researchers discovered a fragment of bones from a girl whose mother was a Neanderthal, and the father was Denisovan in a remote cavern in Siberia. In a new study, researchers estimate that this hybrid child lived between 79,100 and 118,100 years. Modern humans, discovered by scientists, have a common ancestor with the Denisans and Neanderthals who lived about 600,000 years ago. Later – approximately 390.00 years ago – Neanderthals and Denisovian growers are divided.
Over the past decade, Karl Zimmer reports in the New York Times, the Denisova Cave, "gave some of the most fascinating fossils ever found: the naked eye, they do not have much to look at – a few teeth, bone fragments. But fossils contain DNA which dates back to tens of thousands of years.This genetic material shows that the Denizens were a separate branch of human evolution, a lost vine.At some time in the distant past, the Denisites disappeared-but not before moving to modern humans Today, people in places like the East Siggraph Asia and New Guinea still carry fragments of Denisova DNA. "
The August discovery in the cave in the isolated river valley in Siberia was "sensational," says Johannes Krause, who studies the ancient DNA at Max Planck Institute of Human History in Jena, Germany. "Now we have the love child of two different hominine groups, discovered where members of both groups were found. Over time, many things happen in a cave."

"Everyone said:" These Denisovans, we have no idea how old they are, "says Catherine Duuka, an archeologist at the Max Planck Institute for Human History in Germany. Over the past six years, Dr Duka and other experts have created history of the cave, which dates 103 layers of sediment on the floor of the cave, as well as 50 objects found in them, including bones, pieces of coal and tools.
Max Planck scientists have discovered this chronology in several papers published yesterday, which shows that people have occupied the cave perhaps for as long as 300,000 years, raising some intriguing hints that the Denizens may have been capable of sophisticated thought at the same level as modern humans.
The results of the August survey suggest that a woman may have been just a teenage girl when she died more than 50,000 years ago, too young to leave much of her world. But part of one of her bones, unearthed in the cave in 2012, could make her famous. Pretty old DNA retained within a 2 cm fragment to reveal its surprising origins: It was a direct offspring of two different types of antique people, Neanderthals and the mysterious Demmin's demonic groups, which separated from each other over 390,000 years ago.

An analysis of the genome of a woman, Gretchen Vogel continues in science, shows that her mother was Neanderthal, and her father was Denisovan, a mysterious group of ancient people discovered in the same Siberian cave in 2011. It is the most direct proof, however, that various ancient people were measured by each other and had offspring.

Based on other ancient genomes, the researchers have already concluded that Denisovans, Neanderthals and modern humans fit into ice Europe and Asia. The genes of both archaic human species are present in many people today. Other fossils found in the Siberian cave showed that all three species lived there at different times.
Vivienne Elton, a paleographer at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who made the ancient DNA analysis, says that when she saw the results, her first reaction was disbelief. Only after repeating the experiment were convinced several times that she and her colleagues from Leipzig – Svante Piabo, Fabrizio Mafezeni and Benjamin Verno.
That one direct offspring of the two ancient people was found among the first few fossil genomes found by the cave suggest, Psabo says: "when these groups met, they actually interfered quite freely with each other."
