In August 2018, researchers discovered a bone fragment from a girl whose mother was a Neanderthal, and her father was Denisovans in a remote cave in Siberia. In the new study, researchers estimate that this hybrid child lived between 79,100 and 118,100 years ago. Modern people, scientists discovered, have a common ancestor with Denisovans and Neanderthals who lived about 600,000 years ago. Later – about 390.00 years ago – the Neanderthal and Denisovan lines split.
Over the past decade, Carl Zimmer's New York Times, Denisov's Cave, has given some of the most exciting fossils ever found. With the naked eye they don't have much to look at – some teeth, pieces of bone. But fossils contain DNA that is tens of thousands of years. This genetic material shows that Denisovans was a separate branch of human evolution that has disappeared from the tribe. At some point in the distant past, Denisovan disappeared – but not before the mutual fusion with modern people. Today people in places like East Asia and New Guinea still carry Denisovan DNA fragments. ”
In August, the discovery of a cave in an isolated river valley in Siberia was "sensational," said Johannes Krause, who studies at the ancient DNA Max Planck Institute of Human History in Yen, Germany. “Now we have a child of two different hominine groups, where the members of both groups were. There is a lot going on in one cave over time. ”
Homo Naledi, recently discovered species – "Maybe we've been a human evolutionary story all the time"
"Everyone said," These Denisovani, we have no idea how old they are, "said Katerina Douka, an archaeologist at the German Institute of Human History, Germany. layers on the cave floor, as well as 50 items found there, including bones, charcoal and tools.
Max Planck scientists discovered this chronology in the paper pairs published yesterday, showing that people, perhaps as long as 300,000 years of beer, created some intriguing tips that Denisovans might be capable of with modern people.
A study conducted in August shows that a woman was probably just a teenager when she died more than 50,000 years ago, too young to leave a big mark in her world. But one of her bones discovered in the cave in 2012 can make her famous. Enough ancient DNA remained in a 2-centimeter fragment to discover its amazing ancestor: She was a direct descendant of two different species of ancient people – the Neanderthal and the mysterious Denisovan – of extinct hominine groups that differed more than 390,000 years ago.
A new study reveals the early "ghost species" that are interrelated with humans
The analysis of the female genome, continued in Gretchen Vogel's science, indicates that her mother was Neanderthal, and her father was Denisovan, a mysterious group of ancient people, discovered in the same Siberian cave in 2011. were interconnected and had offspring.

Based on other ancient genomes, the researchers had already concluded that Denisovans, Neanderthals and modern people associate Europe and Asia. Nowadays many people have genes of both archaic human species. Other fossils found in the Siberian cave showed that all three species lived at different times.
Viviane Slon, a Paleogeneist at Max Planck Evolution Anthropology Institute in Leipzig, Germany, who did an ancient DNA analysis, says when she saw the results, her first reaction was infidelity. Only after several attempts did she and her colleagues Leipzig – Svante Pääbo, Fabrizio Mafessoni and Benjamin Vernot – convince.
"The first two offspring of human beings were found among the first few fossil genomes discovered in the cave," "Pääbo" says, "When these groups met, they were actually quite confused."
