Excerpt from the linked summary^1 by Dyani Lewis, about research^2 by Hongru Wang et al.:

>The Tibetan Plateau extends from the northern edge of the Himalayas across 2.5 million square kilometres. It is a high-altitude, dry and cold region.

>Despite its inhospitable environment, humans have been present on the plateau since prehistoric times. Denisovans, extinct hominins that interbred with both Neanderthals and the ancestors of modern humans, lived on the northeastern edge of the plateau 160,000 years ago.

>Stone tools made 30,000–40,000 years ago are further signs of an early human presence in the region.

>But when people established a permanent presence on the plateau — and where they came from — has been a matter of debate, says Qiaomei Fu, an evolutionary geneticist at the Chinese Academy of Sciences in Beijing, who led the study.

> 

>Fu and her team sequenced ancient genomes from the remains of 89 individuals, dated to 5,100–100 years ago, unearthed from 29 archaeological sites.

>Their study confirms that permanent occupation of the region pre-dates historical records.

>It also paints a complex picture of where early Tibetans migrated from, and how their interactions in the region and with their lowland neighbours shaped their heritage.

>Analysis of the genomes reveals that the ancient occupants of the Tibetan Plateau have strong genetic links to the Tibetan, Sherpa and Qiang ethnic groups that live on or near the plateau today.

>Comparisons of the oldest genomes with ancient and living people across Asia suggest that the ancestors of modern Tibetans arrived on the plateau from the east.

>By contrast, India and the rest of the Asian subcontinent were populated by immigrants from eastern Eurasia and central Asia.

And now China is actively trying to erase that

I don't know the study says the tibetan people came from the east. What area is currently east of tibet? yeah, china

That doesn't mean that Tibetans are Chinese.

You could use a similar logic with the U.K. Genetic studies indicate British people came from the East. What is to the East of Britain. Italy! Ergo British are Italians.

When you think of emigration and movements of peoples occurring in waves over centuries, you soon realise that the kind of reasoning in statements such as these are flawed.

And similarly, ancient maps show that Britain was part of the Roman Empire, therefore Italy has a territorial claim to modern England.

Often a good way to find if a statement is logically failed is to attempt to find other analogous situations, see if the same logic holds up, and if it doesn't work out why it doesn't.

they sound chinese enough for chinese militarists to justify troop movements. I agree English sound italian enough for italian militarists to justify troop movement.... and in the end isn't that all that matters?

For a given value of "justify"
