I normally dont really reed any of this kind of stuff but i find this fascinating and i would like to share it
.
Hope it's in the right topic couldnt find any other that was more suited.

Ancient DNA reveals humans living 40,000 years ago in Beijing area related to present-day Asians, Native Americans

An international team of researchers including Svante Pääbo and Qiaomei Fu of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, sequenced nuclear and mitochondrial DNA that had been extracted from the leg of an early modern human from Tianyuan Cave near Beijing, China. Analyses of this individual's DNA showed that the Tianyuan human shared a common origin with the ancestors of many present-day Asians and Native Americans. In addition, the researchers found that the proportion of Neanderthal and Denisovan-DNA in this early modern human is not higher than in people living in this region nowadays. Humans with morphology similar to present-day humans appear in the fossil record across Eurasia between 40,000 and 50,000 years ago. The genetic relationships between these early modern humans and present-day human populations had not yet been established. Qiaomei Fu, Matthias Meyer and colleagues of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, extracted nuclear and mitochondrial DNA from a 40,000 year old leg bone found in 2003 at the Tianyuan Cave site located outside Beijing. For their study the researchers were using new techniques that can identify ancient genetic material from an archaeological find even when large quantities of DNA from soil bacteria are present. The researchers then reconstructed a genetic profile of the leg's owner. "This individual lived during an important evolutionary transition when early modern humans, who shared certain features with earlier forms such as Neanderthals, were replacing Neanderthals and Denisovans, who later became extinct", says Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology, who led the study.

The genetic profile reveals that this early modern human was related to the ancestors of many present-day Asians and Native Americans but had already diverged genetically from the ancestors of present-day Europeans. In addition, the Tianyuan individual did not carry a larger proportion of Neanderthal or Denisovan DNA than present-day people in the region. "More analyses of additional early modern humans across Eurasia will further refine our understanding of when and how modern humans spread across Europe and Asia", says Svante Pääbo. Parts of the work were carried out in a new laboratory jointly run by the Max Planck Society and the Chinese Academy of Sciences in Beijing.

Nice find, It is amazing that we find more and more old bones and proof of much older civilizations than we ever imagined.

Any stone age tools or weapons found with or near the bone? I don't know how complete the stone tool/point record is in this area, or how they compare to later points in America and elsewhere.

I believe you will find antecedants to their tool
tech in north America and not in Asia.

Not that i have found out about but that could be indeed and to be honest i have no idea i will try to find out more

Native Americans and certain Tibetan tribes had exactly the same traditions, customs and religious practises/beliefs. They also look quite alike. Here is the material evidence that they were once linked, and perhaps their lifestyle is much older and was developed by this common ancestor?

If you want to hear more on these customs and values, it is quite beautiful in my opinion, youtube:

I don't know why so many historians and archaeologist find it so hard to believe that man(DNA as today) was around 40,000 years ago and not the more ancient ancestor. This just goes to show that maybe the evolution timeline that we think is accurate may not be so. This is an amazing find that I hope will really open the eyes of people. But of course I doubt that the main stream media will report these finds because it validates the theories of Forbidden Archaeologist, and they won't do that.

The report is by scientists and reported by the MSM -that modern humans were in that part of Asia 40,000 years ago is not unusual or unexpected.

Errm, anatomically modern humans are considered to have been around for 200,000 years, so I'm not sure what you are on about.

Well, time will tell. However this discovery is exactly in line with what is expected by the currently accepted human development and migration timeline.
