However such outcomes do usually make sense when genetic similarities & ancient migrations are taken into consideration. As mentioned already according to Ancestry’s own information the “typical native” from South Asia would score 85% “Asia South”. At first sight it may even seem impossible or absurd when for example a person from Bangladesh would show a trace region of “Native America” or a person from India is reported with a small amount of “Finland/Northwest Russia” or an Australian Aboriginal receives a trace amount of “Asia Central”. Welcome to Anthrogenica, an independent community-funded, community-led discussion forum catering towards all aspects of anthropology and population & consumer genetics. And in addition it also features the average AncestryDNA results for the Gujarati sample group (GIH) from the 1000 Genomes database. Naturally in individual cases recent and already known ancestry from the Pacific might still occur. Sofar i myself have not seen any specification of Ancestry’s South Asian samples. However many if not most Afro-descendants actually also have additional non-African ancestry. However for many others it seems that this type of DNA is usually reported as an unexpected trace region which catches them by surprise. Ultimately this will all be up to your own personal preferences. Naturally not to the full extent but possibly representing a more distinctive remnant portion of it. See also the introduction to this page for discussion in greater detail. One of the more sensationalist theories even once speculated about a Celtic presence in Central Asia! However many if not most Afro-descendants actually also have additional non-African ancestry. Then again it is human nature to be intrigued by seemingly mysterious details, even at the risk of getting caught up in them. Admixture analysis is not perfect but if you familiarize yourself with its inherent limitations you will realize that is in fact unrealistic to expect “100% accurate” results. Leaving aside any superficialities or ideological motivations and just taking an unbiased look at their distinctive culture, their languages, their known history and prehistory it is already crystal clear that the Melanesians are a unique group of people who should be respected as such. I’m guessing though it might be indicative of both genuine Central Asian (Afghan) lineage as well as Tibetan/Nepali origins. The accuracy of these name definitions cannot be guaranteed. Most likely due to (very) ancient shared origins the socalled “Melanesia” region is also consistently reported for South Asians, even if only in small amounts. My survey is suggesting that people from these parts of South Asia are also most likely to score consistent and above trace-level scores for socalled “Melanesia” and “Asia East” (see. All of them ultimately descended from the same Out-of-Africa migration. Number of occurrences among people self-identifying as Asian & Pacific Islander, Surname rank among Asians & Pacific Islanders, % of people with surname self-identifying as 'Asian & Pacific Islander'. the description is the meaning and history write-up for the name; separate search terms with spaces; search for an exact phrase by surrounding it with double quotes. Such segments would be least likely to be affected by recombination but rather get passed on intact across the generations. I suppose it could also just indicate unique DNA markers within the Aboriginal genepool not found among the 28 Melanesian samples used by AncestryDNA. Receiving a multitude of trace regions does therefore not per se imply that you have a confusingly diverse background. It remains to be seen how representative these samples might be to capture the genetic diversity existing within the vast Indian subcontinent which is home to about 1.7 billion people! STEPHEN Nauruan. The greatest number of my admittedly still very minimal South Asian survey samples comes from India. But only whenever these details were available to me and obviously only meant as an approximation of recent family locations (within the last 2 generations). Therefore it seems reasonable to assume that Pakistani samples from the HGDP database are used to calculate “Asia South” scores on AncestryDNA. People from Melanesia, a region in the South Pacific encompassing Papua New Guinea and surrounding islands, may carry genetic evidence of a previously unknown extinct hominid species , Ryan Bohlender reported October 20 at the annual meeting of the American Society of Human Genetics. I have asked for prior consent whenever i could but regrettably wasn’t able to do so in all cases. Denisova Admixture and the First Modern Human Dispersals into Southeast Asia and Oceania, A genomic history of Aboriginal Australia (Malaspinas et al., 2016), Unprecedented study of Aboriginal Australians points to one shared Out of Africa migration for modern humans, The Lascars : The forgotten Diaspora in the Indian Ocean, Indian Slaves in South Africa: A little-known aspect of Indian-South African relations, https://www.ancestry.com/cs/dna-help/ethnicity/trace-regions, Follow Tracing African Roots on WordPress.com. I checked out the Huguenot Society, and they have Bouchers on record as confirmed Huguenot refugees to Britain in the 17th … But not to the full extent of 100%! The following tables include all surnames with over 0.001% frequency in the US population during the 1990 census. I copied these results from an attachment to a recent paper done by the Ancestry research team and published in Nature (“Clustering of 770,000 genomes reveals post-colonial population structure of North America”, 2017). I am not aware of any historically plausible and documented connections for what it’s worth. But it’s worth repeating again that without additional clues and corroborating evidence your attempts to trace back trace regions to specific ancestors or ethnic groups could very well lead to a dead end.
