ONe now sees where the "Solutrian Hypothesis" is coming from.
My own current working hypothesis is that X mt DNA evolved along the Black Sea before it flooded following the Holocene Start Impact Events.
For impacts and the rise in sea levels see:
This maritime population then spread through out the Mediterranean and then to the Atlantic Coast. It first appears in North America around 8,350 BCE as Canadian Red Paint, an advanced maritime tool kit with no antecedent, which in turn evolves into Canadian Red Ochre, which in turn evolves into Old Copper Culture, which in turn evolves into Adena Culture.
The Adena were very tall:
Dragoo had hypothesized that Adena was a selective breeding within the C mt DNA haplogroup, but my working hypothesis is that they were X mt DNA.
Arguing against the "Solutrean Hypothesis" for X mt DNA is easy, as no archaeological continuity in cultural remains has been indicated nor shown.
I have been told that in Eastern Europe this population is now being referred to as "CroMagnoid", but have not checked this from myself yet.
