But what does that mean? Somebody in my line had to interact with the Neanderthal in order to have that autosomal DNA. Are you telling me that my 2.9% is from my maternal line?
It's autosomal, it could come from 1000's of your lines (1 is extremely unlikely) OR it could be a ghost that exists due to modern man and Neanderthals having a common ancestor.
Hmm, I'm wondering about the latter option since most humans do not have more than 4%. I just find it intriguing that its DNA was extracted in Croatia, which would mean sometime beyond 30,000 years ago a precursor to perhaps to haplogroup P may have been around or near Europe. Or maybe it was at a time when MNOPS existed around the Middle East?
