Are the brits closer to cheese eating surrender monkey's or to the pillaging Swedes?
Neither. While the mapping displayed a wide diversity from various time periods, it suggested a concentration of early Briton (not to be confused with British) population, predating early Etruscans. These were a people western France, the British Isles, including Eire, whom the Romans called Picts. Today, their gene markers appear in northern Iberia, less so in France, as far east as Hungary. parts of Romania, Bulgaria and Albania, among other trace locales. This is giving support to recent linguistic theories claiming Gaelic is homegrown and exported, dating back prior to Etruscan expansion, which itself predates development and absorption by the Romans by more than 1,500 years. The greatest concentration of the gene patterns are found in Wales, some of the Irish isles, and Pyrenees country in Spain and France.
The diversity of gene and chromosome patterns throughout the isles suggest a far longer centering of sea trade route destinations enjoying the isles. Some are beginning to view gene and chromosomal evidence of greater value than fossilized and other archeological evidence, more dependable, more explicitious. This is leading to greater exploration of the same for flora and other fauna.
I cannot say I understand the mechanics, but I find the theoretical results fascinating.
The Swedes didn't do all that rape and pillaging in the Isles, you are confusing them with the Danes, a separate gene set that shows some assimilation with Swedish influences, well after raiding the isles was no longer fashionable. The Danes being mostly early Germanic and other migratory groups from northern India. More and more genetic evidence is rising to show migrations traveled in both directions across the Russian, central European and Asian steppes, many times over through different eras. Since nomadic and migratory peoples tend not to leave much archeological evidence as we know it, this provides another avenue of learning about mankind and concurrent environmental backdrops, through genetic research.
BTW, no one consumed as much cheese as the early Greeks, Romans, Persians and Turkish peoples. This supports theories of the gene variation allowing humans to consume dairy products made from the milk of other species, originating in the Anatolian region and then spreading in all directions, creating a massive alteration of and for diverse diets.
So much evidence, so many interpretations of evidence, so many theories and speculations differed by later cultural agendas, yet we know so little as truth. Sounds like American politics.
