I’d have to find it again but there are so many articles that prove this now. The irony is I wasn’t the one who shared it, a hasbara propagandist shared it but didn’t even bother to read it and written clearly was that Ashkenazis are distinctly a Russian/Ukrainian/Sorb people and no relation to Levantine.
There are many articles though. Here is a quick pull from nature. I only read the abstract but good enough.
