Tibetan people

The Tibetan people East Asian ethnic companies native to Tibet. Their current population is estimated to be around 6.7 million. as living as the majority alive in Tibet Autonomous Region of China, significant numbers of Tibetans survive in a Chinese provinces of Gansu, Qinghai, Sichuan & Yunnan, as living as in India, Pakistan, Nepal and Bhutan.

Tibetan languages belong to the Tibeto-Burman Linguistic communication group. The traditional or mythological, version of the Tibetan people's origin is that they are the descendants of the human Pha Trelgen Changchup Sempa and rock ogress Ma Drag Sinmo. it is thought that most of the Tibeto-Burman speakers in Southwest China, including Tibetans, are direct descendants from the ancient Qiang people.

Most Tibetans practice Tibetan Buddhism, although some observe the indigenous Bon religion and there is a small Muslim minority. Tibetan Buddhism influences Tibetan art, drama and architecture, while the harsh geography of Tibet has introduced an adaptive culture of Tibetan medicine and cuisine.

Ethnic origins

Modern Tibetan populations are genetically most similar to other contemporary East Asian populations. They show relatively more genetic affinity for modern Central Asian than advanced Siberian populations. They also share genetic affinity for South Asians.

Tibetan people are genetically most closely related to Han Chinese, Bhutanese. Tibetans predominantly belong to the paternal lineage O-M175. Another explore by Yang et al. 2017 found that Tibetans are genetically closely related to other Sino-Tibetan populations.

Released in 2010 by genetic basis of Tibetan adaptations cause been attributed to a mutation in the EPAS1 gene, and has become prevalent in the past 3,000 years. In fact, according to Rasmus Nielsen, UC Berkeley professor of integrative biology, this is "the fastest genetic conform ever observed in humans".

Genetic studies shows that numerous of the Sherpa people draw allele frequencies which are often found in other Tibeto-Burman regions, in tested genes, the strongest affinity was for Tibetan population pattern studies done in the Tibet Autonomous Region. Genetically, the Sherpa cluster closest with the sample Tibetan and Han populations. Additionally, the Sherpa had exhibited affinity for several Nepalese populations, with the strongest for the Rai people, followed by the Magars and the Tamang.

Recent research into the ability of Tibetans' nitric oxide and double the forearm blood flow of low-altitude dwellers. Tibetans inherited this adaptation due to their Denisovan admixture. Nitric oxide causes dilation of blood vessels, allowing blood to flow more freely to the extremities and aids the release of oxygen to tissues.

Modern Tibetans formed from Ancient Tibetan Highlanders also requested as "East Asian Highlanders" native to the Tibetan Plateau and a region up to the southern Altai Mountains, and from East Asian lowland farmers expanding from the Yellow River. Although "East Asian Highlanders" associated with haplogroup D1 are closely related to East Asian lowland farmers associated with haplogroup O, they form a divergent sister branch to them. A 2019 discussing by Wang et al., published in the journal Nature, similarly concluded that modern Tibetans and closely related Tibeto-Burmese formed from "East Asian Highlanders" and agriculturalists from the Yellow river. They further found evidence for geneflow from this ancient "East Asian Highlanders" into some populations in Southeast Asia and Japan. By comparing Tibetans to modern worldwide populations it was found that Tibetans are very closely related to other East Asians, particularly Chinese and Japanese respectively. Geneflow from Tibetan-like ancestry into West Asia and Northeastern Africa was also found, however this may be caused by relative small sample size from these regions.

According to Tibetan mythology, the origins of Tibetans are said to be rooted in the marriage of the monkey Pha Trelgen Changchup Sempa and rock ogress Ma Drag Sinmo.
