With current technology, AncestryDNA has, on average, an accuracy rate of over 99 percent for each marker tested. The bone density is quite a bit higher in the African Americans. It is also higher in men than in women. Asian persons tend to have bone density that is as low or even lower than Caucasians. Hispanic people have bone density that is about the same or a little bit higher than Caucasians.

While the Indo-Aryan linguistic group occupies mainly northern parts of India, genetically, all South Asians across the Indian subcontinent are descendants from a mix of South Asian hunter-gatherers, Iranian hunter-gatherers, and Central-Asian steppe pastoralists in varying proportion. The new study says the Iranians arrived in India before agriculture or even herding had begun anywhere in the world. In other words, these migrants were likely to have been hunter-gatherers, which means they did not bring a knowledge of agriculture.
Punjabis are mainly an admixture of Indo-Aryans and Dravidians. Culturally yes Punjabis are different from other subcontinent communities. They have their own language, traditions, foods, music, literature etc But racially they are linked to rest of the subcontinent. These Zagrosian herders mixed with the earlier inhabitants of the subcontinent — the First Indians, descendants of the Out of Africa OoA migrants who had reached India around 65, years ago — and together, they went on to create the Harappan civilisation.
As far as we know, Neanderthals evolved outside of Africa, perhaps in response to the ice ages of Europe. Our ancestors remained in Africa where perhaps as early as , years ago, as revealed from recent redating of the Moroccan site of Jebel Irhoud, were well along in the process of evolving into modern humans.
The more individuals studied, the easier it becomes to detect distinct clusters statistical noise is reduced. Using measuring tools called calipers — with adjustable pieces that slide or spread apart to measure length or thickness — forensic anthropologists take hundreds of measurements from a skeleton to assess race.
B positive is an important blood type for treating people with sickle cell disease and thalassemia who need regular transfusions.
These conditions affect South Asian and Black communities where B positive blood is more common. I call bullshit or in other words perhaps highly educated guesswork.
Or perhaps at least be related to some of the people who currently can claim to have been descended from those survivors of the Uighur people? Hello, Could anyone validate ancestry.

Valerie Ross Valerie Ross studied cognitive neuroscience and creative writing at Stanford University.
The allele is almost totally absent among Central and South American Indians. Overall in the world, B is the rarest ABO blood allele. It reaches its highest frequency in Central Asia and Northern India , while it is believed to have been entirely absent from Native American and Australian Aboriginal populations prior to the arrival of Europeans in those areas.
However, there are relatively high frequency pockets in Africa as well. However, it is more common in some regions. Europeans have the lowest frequency of this blood type for any continent.
The lowest known frequency is found among the Basques of the Pyrenees Mountains between France and Spain.
