The Neanderthals and the Denizens DID lived in a remote Siberian cave thousands of years ago and may even have used the shelter at the same time, the study reveals
- Two new studies are trying to narrow the history of human ancestors
- Artifacts found in the Denisova Cave showed that the Denisovites and the Neanderthals lived there
- The study suggests that the site was home to Denisovani some 287,000 years ago
- The profession can be overlap with the arrival of the Neanderthals 193,000 years ago
Two separate types of human ancestors may have both occupied the cave in Siberia, at the same time thousands of years ago.
The researchers have long worked on narrowing the timeline of the Hominic occupation in the Denisova cave, after artefacts, including stone tools and bones, were found at the site.
A couple of new discoveries analysis studies now suggest that the site was home to Denisovani some 287,000 years ago, before overlapping with the advent of Neanderthals before 193,000 years ago.
Much about the Denis remains a mystery; although their existence on the site is known from fragments of bones and teeth, the size and complexity of the cave (in the picture) makes it difficult to study
The two new studies published in Nature this week could help to improve our understanding of the history of missing hominins.
Much about the Denis remains a mystery; although their existence on the site is known from fragments of bones and teeth, the size and complexity of the cave made learning difficult.
In one of the new efforts, a team led by researchers at the University of Wollongong used a technique known as the optically stimulated luminescence that dates back to the sediments of the Denisova cave.
This allowed them to evaluate when certain mineral grains were last exposed to sunlight in order to create a time frame for the fossils and artifacts found there.
According to the team, the occupation of the site extends over 300,000 years ago 20,000 years ago.

The researchers estimate that the Denisites appeared about 287,000 years ago and stayed there for 55,000 years.
The Neanderthals, on the other hand, appear in the records 193,000 years ago, 97,000 years ago.
In the second paper, the researchers used radiocarbon to evaluate all the known fossils of Denisovan.
The team presented a total of 50 new dates on the radioactive node and described three new Desiccant fossil fragments.
Their analysis showed that Denisovans were in place 195,000 years ago, with the youngest dating from about 76,000 to 52,000 years.

Who were Denisovani?
Denisovci are the extinct kind of man who seems to have lived in Siberia, and even to southeast Asia.
Although the remains of these mysterious early humans were discovered only in one place – the Denisova cave of the Altai Mountains in Siberia, the DNA analysis showed that they are widespread.
The DNA of these early humans has been found in the genomes of modern humans in a wide area of Asia, suggesting that they once encompassed a wide spectrum.
DNA analysis of a finger-bone fragment of fingers in 2010 (in the picture) belonging to a young girl revealed that Denisovans are related to, but different from the Neanderthals.
It is believed to have been the sister species of Neanderthals, who lived in western Asia and Europe at the same time.
Both species appear to have been separated from a common ancestor some 200,000 years ago, while they were split from the modern human homo sapiens vase about 600,000 years ago.
The bones and ivory elephants found in the Denisova cave were discovered in the same layers of sediment as Denisovan fossils, which led to suggestions that they had sophisticated tools and jewelry.
The DNA analysis of a five-digit cube fragment in 2010, which belonged to a young girl, revealed that it was species, but different from the Neanderthals.
Later genetic studies suggest that the ancient human species separated from the Neanderthals sometime between 470,000 and 190,000 years.
Anthropologists have since been confused about whether the cave was a temporary shelter for a group of these Denisovci or formed a more permanent settlement.
DNA from molar teeth belonging to two other persons, one adult man and one young woman, showed that they died in the cave at least 65,000 years earlier.
Other tests have shown that the young woman's tooth can be as old as 170,000 years.
The third molar is considered to belong to an adult man who died about 7,500 years ago before the girl whose discovery was discovered.
Bone points and dental pendants found in the cave can also be the oldest Denisovan artifacts found in Northern Europe, researchers say.
They were dated about 49,000 to 43,000 years ago.
Together, the two new studies make a more complete time frame for living.
"Although there is still some insecurity about the detailed ages of the wreckage – given the nature and complexity of deposits and the methods used for dating – the general picture is now clear," archaeologist Robin Dellel wrote in an accompanying article "News and Views".
