Two different types of human ancestors may have occupied a cave in Siberia thousands of years ago.

Researchers have been working for a long time To limit the time of occupation of the cave in the Denisova Cave, numerous artifacts were found at the site, including stone tools and bone points.

A few recent studies analyzing the findings now suggest that the site was near Denisovans 287,000 years ago, before possibly being overlapped with the arrival of Neanderthals 193,000 years ago.

  Much about the Denisovans remains a mystery; Although their existence on the ground is known from fragments of bones and teeth, it is difficult to study due to the size and complexity of the cave (pictured).

Much about the Denisovans remains a mystery. Although their existence on the ground is known from fragments of bones and teeth, it is difficult to study due to the size and complexity of the cave.

In a recent effort, a team led by researchers from the University of Wollongong used a technique known as optically-stimulated luminescence dating to analyze sediments from Denisova Cave.

This allowed them to estimate when certain mineral grains were last exposed to sunlight to create a timeline for the fossils and artifacts found there. Researchers have long worked to limit the time of occupancy of hominins in Denisova Cave after a series of artefacts, including stone tools and stoneware, bone points (pictured) were found on the site ” class=”blkBorder img-share” />

Researchers estimate that the Denisovans had appeared 287,000 years ago and remained there until 55,000 years ago.

Neanderthals, on the other hand, are included in the records from 193,000 years to 97,000 years ago.

In the second work, researchers used radiocarbon dating to evaluate all known Denisovan fossils.

The team presented a total of 50 new radiocarbon dates and described three new Denisovan fossil fragments.

Their analysis showed that Denisovans were already in the site 195,000 years ago, with the most recent being around 76,000 to 52,000 years ago.

  Recent studies analyzing the findings indicate that the site was inhabited by Denisovans 287,000 years ago, before possibly overlapping with the arrival of Neanderthals 193,000 years ago

. A few new studies analyzing the discoveries now suggest location 287,000 years ago as the home of Denisovan before possibly overlapping with the arrival of Neanderthals 193,000 years ago

WHO Were the Denisovans?

The Denisovans are an extinct species of humans who seem to have lived in Siberia even to Southeast Asia.

Although remains of these mysterious early humans were only discovered in one place – the Denisova Cave in the Altai Mountains in Siberia – DNA analysis showed that they were widespread.

DNA from these early humans was found in the genomes of modern humans in much of Asia, suggesting that they once covered a broad spectrum.

  DNA analysis of a fragment of small finger bones (picture) belonging to a young girl revealed in 2010 that the Denisovans were a species related to Neanderthals but different.

The DNA analysis of a fragment of small finger bones (picture) belonging to a young girl revealed that the Denisovans were a related species, but unlike Neanderthals.

It is believed that they were a sister of the Neanderthals who lived in Western Asia and Europe at about the same time.

The two species occur about 200,000 years apart from a common ancestor, while they split off from the modern human Homo sapien line some 600,000 years ago.

Bone and ivory pearls found in Denisova Cave were found in the same sedimentary layers as the Denisovan fossils, suggesting they had elaborate tools and jewelry.

DNA Analysis of a fragment of a fifth digit of a finger bone in 2010 that belonged to a young girl revealed that it was a species related to Neanderthals.

The human species split off from the Neanderthals about 470,000 to 190,000 years ago.

Anthropologists have since become confused as to whether the cave was a temporary shelter for a group of these Denisovans or whether it was a more permanent settlement.

DNA from molar teeth of two other individuals, an adult male and a young female, stated that they had died in the cave at least 65,000 years previously.

Other tests indicated that the young woman's tooth could be as old as 170,000 years.

It is believed that a third molar has belonged to an adult male who died some 7,500 years before the girl whose little finger was discovered.

Bone points and tooth tags found at the cave According to the researchers, the oldest Denisovan artifacts can be found in Northern Europe.

These were dated about 49,000 to 43,000 years ago.

Together, the two new studies provide a more complete time line of population.

"Although there may still be s In view of the nature and complexity of the deposits and the dating methods used, the general picture is now clear, archaeologist Robin Dennell wrote in an accompanying article by News & Views.
