Detecting modern human individual fossils 40,000 years old

(scienceinfo.net) - A relative from Tianyuan cave: a human being who lived 40,000 years ago seems to be a relative of many Asians and native Americans today.

Ancient DNA has revealed that humans who lived about 40,000 years ago in the area near Beijing, seem to be related to Asians and Native Americans today .

An international team of researchers, including Svante Paabo and Qiaomei Fu scientists of Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, extracted the chain and mitochondrial DNA from the foot of a Modern personfrom ancient Tianyuan cave near Beijing, China.This DNA analysis of the individualshows that the Tianyuan have the same origins as the Asian and Native American ancestors.In addition, the researchers found that the ratio of DNA of Neanderthal and Denisovan inthis ancient person was not higher than thoseliving in this areatoday.

Humans are similar in shape to humans today with fossils located throughout Eurasiabetween 40,000 and 50,000 years ago.Genetic relationships between modern people appear early and populations today are still notestablished.Qiaomei Fu, Matthias Meyer and colleagues at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, used a new technique to identify ancient genetic materialfrom a fossil evenin large quantities. DNA from bacteria in the soil.

The researchers then rebuilt a genetic profile of the above fossilized ancient person .Svante Paabo of Max Planck Institute for Evolutionary Anthropology said:" This individual lives in an important period of evolutionary transition when the ancient people shared some features with forms. previously as Neanderthals, replaced Neanderthals and Denisovans, but this person was later extinct . " Max Planck leads the research   said above .

Genetic records show that this early modern individual was a relative of many Asians and Native Americans today, but genetically separated from today 's European ancestors . In addition, Tianyuan individuals do not contain much more Neanderthal or Denisovan DNA than those currently living in this area . 'More analysis of these early modern people across Eurasia will help us know more precisely when and how modern people spread across Europe and Asia , ' he said. Svante Paabo said.

Much of the work was done in a new laboratory run by the Max Planck Society research institute and the Chinese Academy of Sciences in Beijing.
