I guess “ Western Europe” can be almost anything you want it to be. There are people who use the term to encapsule everything outside of the former Soviet Union. That’s probably the broadest definition. For other, “Western Europe” seems to be the area where Romance languages and Germanic languages prevail. I don’t believe I have ever previously seen a definition of “Western Europe” as narrow as just “France and Germany.” I wonder what the Irish, British, Spanish, Portuguese, Belgians, Dutch, Luxembourgers & others universally accepted as Western European would think of being excluded. The Wikipedia definition of Western Europe is rather conservative, and includes all those nations. Others would include Scandinavia, Switzerland & other nations. If we went back in time some 15 years or more, we may not have had the DNA markers to distinguish Celtic from Germanic or Italic, but we can do better in this day and age. My 23andme test is 8 years old and did better. To me, equating “Western Europe” with “France and Germany” is Chris mpsring apples and oranges. They are never going to match.
Perhaps you could point out where I used decimal fractions? Personally I doubt that anyone can be that precise, given that “whole genome” or “fulL Y” testing is far from that, given the gene sites that cannot be read, such as the palindromic zone. I agree with you that decimal fractions suggest a degree of accuracy that we have not yet achieved. I just don’t see where I fell into that error.
