Eurasian forests have produced rare, rare and rare species of primitive man for 200,000 years, according to a new study published on Wednesday.
Denisovans – a Neanderthal cousin – were found to work in 2010 when scientists working in a Siberian cave in southern Siberia were able to get their fingertip from a human-unnamed group.
Unlike Denisov's cave, it was roughly known as the most popular member of the Neanderthal family, making sophisticated hunting groups, making fire, tools, and clothing.
In double papers published in the Nature magazine, nowadays, two international scientists' groups Denisovans lived in the cave 200,000 years ago.
They had to overcome various obstacles that make prototypical dates of people with difficulties to reach that conclusion.
"It is a huge challenge that human traces are microscopic, it's 2 cm tall and it is really difficult for the dates to fall out of the radio circuit," Tom Higham, director. Researchers at the Oxford University Radiocarbon Accelerator Unit and AFP have said.
Carbon dating, to show the age of organic matter that uses half the radioactive carbon isotope, is only reliable in terms of 50,000 years.
Higham and their team have discovered some broken parts of the bone, one of them obtained a DNA sample.
They then used a mathematical model of carbon data, as well as determining sediment dates, genome mutation rates, and archaeological information when Denisov lived in their homes.
"200,000 years ago, about 50,000 older than Denisov's disappearance," said Higham.
Like human remains, researchers found perforated toothbrushes, like necklaces, bone marrow, ostrich and stone bracelets. Previously, it was linked to modern humans and, recently, only to Neanderthals.
Objects were found in the cave without any other hominim, Higham said that "probably a description" was the work of Denisovans.
"Earlier (objects) nowadays 49,000 years ago, this is the earliest proof of behavior in the north-east of Eurasia, if not the continent of Eurasia," he said.
"The evidence suggests that they are probably made by Denisovans."
If confirmed, the discovery would know how we know the lifestyle and socialization of our ancestors.
Denisova Cave did the first test in August, when Denny's mid-Neanderthal half-Denisovan hybrid discovered two early human growth species.
According to research on Wednesday, Denny appeared about 100,000 years ago, to say that Neanderthal and Denisovan have disappeared about 40,000 years ago to say thousands of years ago.
In Nature, Robin Dennell at the University of Exeter Department of Archeology said that "it is a strict and compelling time frame for the cave and its contents."
