Hello, I have done a bit of research on Y-DNA and I think I have a good grasp on the main concepts and ideas. But I have many questions about haplogroup E-V13.
Firstly: What is the actual modern frequency map of E-V13?

These are the two maps I see used the most. The first one from Wikipedia the second one from Eupedia. I saw that the one from Wikipedia is from a legitimate but old scientific study, while the one from Eupedia is more recent but I couldn't find how they got it. I feel like the Eupedian map is more accurate because it has British and Spanish regions. Is there no new and accurate map for E-V13? I don't know exactly how these maps are created though (I assume they use samples from populations).
My second question: Why is the Middle Eastern component of E-V13 ignored a lot in discussion and what can it tell us?
It seems that at around E-BY5786 the E-V13 samples become exclusively Arabian. This includes all the Druze E-V13 samples I was able to find on the FTDNA Druze Project. This haplogroup has a TMRCA of 3200 - 1750. In addition to this the FTDNA has a lot of Arabian samples that occur all around the European parts of E-V13.
I have heard people say that the Arabian E-V13 could be from Byzantine or Roman soldiers, how plausible is this?
Related to that is, how come E-V13 is mostly in Europe while all of it's sibling clades are mostly in the MENA region? E-V65, E-V22, and E-V12 all seem to be in the MENA region while E-V13 is in Europe. I don't know if it's just me but I feel like that is unusual.
My third question: Why is E-V13 not common in Afroasiatic speakers like the rest of E-M35?
I feel like E-V13 is an anomaly in some ways in Y-DNA, though I guess all haplogroups probably have their own quirks and mysteries.
