Davidski published a spreadsheet of his K7 Basal-rich ancient admixture calculator results. I've harvested some of those test results to compare to my own.
Sorted to three admixtures.
1. Villabruna (component of Western Hunter-Gatherer) sorted:
2. Basal-rich (component of Early Neolithic Farmer) sorted:
3. Ancient North Eurasian (component of Copper Age Steppe) sorted:
I was surprised just how much Villabruna I had in my results, but clearly, this component is found not only in Villabruna, but also in Iceman / Sardinia (Neolithic Farmer) at 53-55%, and in Steppe Yamna (Bronze Age Steppe) at 34%. Therefore I have inherited substantial Villabruna not perhaps directly, but from early admixtures via Neolithic and Bronze Age settlement of Western Europe.
On Villabruna sorted, my closest neighbours are indeed other British - English, Scottish, and also Dutch and Anglo-Saxon ancient. I'm correctly positioned.
This one is an enigma, but it repeats in other calculators. I receive more Southern European / Neolithic than do most British or indeed North West Europeans. I do have one Swiss 3 x great grandparent, but otherwise, all of my recorded genealogy is South East English. I have more Basal-rich than do other "British" results in the spreadsheet. Why is that? Could have the randomness of genetic recombination given me just a little more of that Swiss line than I should normally expect, or do I have another ancestor from the South within the past several generations, that I'm not yet aware of? Living DNA suggests Tuscan in their test.
My neighbours in Basal-rich are East French, Dutch, and Swiss.
3. Ancient north Eurasian.
This trades with my Basal-rich results. I usually have less Steppe than I would normally expect as a Brit or as a North West European. More Neolithic, less Bronze Age Steppe. It does suggest some unknown Southern European ancestry.
My ANE neighbours are East French, Swiss, and North Italian. One ancient British result not too far away is Romano-British 6DT18. He was a young male (aged 16 to 18 years at death), in a multiple grave with three other men, at Driffield Terrace, York. He carried Y haplogroup R1b1a2a1a.
In summary, for a Brit, even for an Englishman, I have just about expected percentages of Villabruna and Western Hunter-Gatherer ancestry. However, something is atypical in the other two founder mixes. I look more like French or Swiss, with more Basal-rich (Neolithic) and less ANE (Steppe) than the average British or even English.
