Neanderthals and Denisovans BOTH lived in distant Siberian caves thousands of years ago and could even use shelter to learn independently.
- Two new studies are trying to narrow down the history of human beings
- The artifacts found in the Denisov Cave show Denisovans and Neanderthals
- The study shows that the site was home to Denisov 287,000 years ago
- Occupation may have overlapped with the arrival of Neanderthan before 193,000,000
Two separate species of human ancestors can exist in Siberia and at the same time for thousands of years.
Researchers have long been working to shorten the time of hominine occupation in Denisov Cave after artefact, including stone tools and bone points.
A couple of new studies analyzing discoveries now suggest that Denisovans lived 287,000 years ago, before possibly overlapping with the arrival of Neanderthals 193,000 years ago.
Much of Denisovani remains a mystery; Although their presence on the spot is known from bone and tooth fragments, cave size and complexity (pictured) have made learning difficult.
The two new studies published in nature per week could help improve our understanding of the history of extinct hominins.

In one of the new efforts, researchers at Wollongong University conducted an optically stimulated luminescence method to analyze sediments from the Denisov Cave.
This allowed them to appreciate when some mineral waters were last exposed to sunlight to create a time schedule for fossils and artifacts found there.
According to the team, the place of employment from about 300,000 years to 20,000 years.

Researchers estimate that Denisovan appeared about 287,000 years ago and remained there for 55,000 years.
On the other hand, the Neanderthals recorded about 193,000 years ago, 97,000 years ago.
In the second study, researchers used radioactive carbon emissions to assess all known Denisovan fossils.
In total, 50 new radio-carbon dates were presented and three new fossil fragments of Denisovan were described.
Their analysis revealed that Denisov was already in place 195,000 years ago, and the youngest was about 76,000 to 52,000 years ago.

Denisovani are extinct human species that seem to have lived in Siberia and even down to southeast Asia.
Although these mysterious remnants of early people have been discovered in only one place – the Denisov Cave in the Altai Mountains of Siberia, DNA analysis shows that they are widespread.
These early human DNAs have been found in the genome of modern humans in a vast Asian area that suggests they once covered a wide range.
In 2010 (in the picture), the DNA analysis of the pink finger bone fragment belonging to a young girl revealed that Denisovani was a species associated with, but different from, the Neanderthals.
They are believed to be neanderthal sister species that at the same time lived in West Asia and Europe.
It seems that these two species have been separated from the common ancestor about 200,000 years ago, until they split from the modern human Homo sapien line about 600,000 years ago.
The bone and ivory beads found in the Denisov Cave were discovered in the same layers of sediment as the Denisovan fossils, which led to recommendations that had sophisticated tools and jewelry.
The DNA analysis of the fifth digital finger bone fragment, which belonged to a young girl, revealed that it was a species associated with, but different from, neanderthals.
Later, genetic studies showed that ancient human species differed from Neanderthals sometimes 470,000 to 190,000 years ago.
Since then, anthropologists have been surprised whether the cave has been a temporary shelter for this Denisovani group, or whether it has created a more permanent settlement.
DNA from two other human-owned teeth, one adult man and one young woman, showed they died at least 65,000 years earlier.
Other tests show that the young woman's tooth can be as old as 170,000 years.
It is believed that the third molar belonged to an adult man who died about 7,500 years before the girls who were discovered in pink.
Scientists say bone bone and dental pendants can also be the oldest Denisovan artefacts found in Northern Europe.
They were dated around 49,000 to 43,000 years ago.
Both new studies together constitute a more complete population.
"Although there may still be some uncertainties over the remainder of the year, given the nature and complexity of deposits and the methods of dating used – the general picture is now clear," archaeologist Robin Dennel wrote in the accompanying news and views article.
