My Basal-rich K7 Results

David Wesolowski of the Eurogenes Blog, has created a new ancient admixture calculator, the Basal-rich K7.

In his blog, he states: "The Basal-rich K7 is the best ancient ancestry test that I've been able to come up with. It correlates strongly with latest research reported in scientific literature. And, in fact, in some instances it probably trumps latest scientific literature.

For instance, Broushaki et al. 2016 characterized Early Neolithic farmers from the Zagros Mountains, Iran, as 62% Basal Eurasian and 38% Ancient North Eurasian-related (Figure S52). This, considering formal statistics like the D-stat below, with AfontovaGora3 (AG3) as the ANE proxy, is unlikely to be correct, despite the fact that AG3 is a relatively low quality sample.".

Villabruna-related

The Villabruna cluster represents the DNA found in 13 individuals in Europe from after 14,000 years ago.  They were Late Ice Age hunter-gatherers.  They appear to have links with the Near East.  The current thought is that they replaced earlier groups of hunter-gatherers in Europe.  The DNA of people in the Middle East and Europe pulled together at this time, and they may represent an expansion from the South-East.  Much of the Aegean Sea would have been dry, with low sea levels (glaciation), so the migration may have been easy.  It is believed that they had dark skin, and blue eyes.  They were possibly, the last hunter-gatherers of Europe and the Middle East.  They may have contributed to our DNA both through or either, later Asian or European admixtures.

David gives the English average as 56.7%.  My result is 57.1%

Basal-rich

The Basal Eurasians are a hypothetical "ghost" population derived from DNA studies.  It is suggested that they splintered from other modern humans 45,000 years ago, presumably outside of Africa, somewhere around the Middle East.  They significantly contributed DNA to the Early Neolithic Farmers of the Fertile Crescent and Anatolia, and consequently, on to all of us modern West Eurasians.  

 David gives the English average as 26.5%.  My result is 28.8%

Ancient North Eurasian

Another Ice Age hunter-gatherer "Ghost" population, but this one has been associated with human remains and an Upper Palaeolithic culture (Mal'ta-Buret') at Lake Baikal, Siberia.  We know that it significantly contributes to modern West Eurasians, through earlier admixture on the Eurasian Steppes.  Copper Age pastoralists then carried it westwards into Europe with their later expansion.

David gives the English average as 16.6%.  My result is 14.0%

Others

David gives the English averages as SE Asian 0.15, Oceanian 0.07, East Eurasian 0.00% and Sub Saharan 0.00

My results are SE Asian 0.00, Oceanian 0.01, and Sub Saharan 0.05

Comparison with other testers

A remarkable similarity has been observed between many of my East Anglian atDNA results and a Norman tester.  On K7, we are almost identical.  Indeed, we are often closer to each other in results, than I am to other British, and he is to other French.

I'm increasingly recognising that although my East Anglian heritage should in theory bring me closer to North German and Scandinavian results, in practice, compared with other Britons, I am pulled more to the south - to France, and even to Southern European.  Hence, I tend to receive lower ANE than many British, Irish, or Scandinavian, and more Early Neolithic Farmer in ancient admixture tests, than would be expected.

Other than Norman admixture, I struggle to explain this with either known paper recorded ancestry (252 direct ancestors from East Anglia and SE England - 100% English), or with known regional history.
