GGG Ping.
Noooo, dear Lord. Please don't tell me I'm related to....ketchupman.
The more we know, the less we believe about 'settled' scientific facts about our past.
What about 135,000 YA artifacts found in CA?
And so I conclude that 'science' is the evidence of things seen.
Doesn't mean that it's the truth.
Please FREEPMAIL me if you want on or off the
"Gods, Graves, Glyphs" PING list or GGG weekly digest
-- Archaeology/Anthropology/Ancient Cultures/Artifacts/Antiquities, etc.
Gods, Graves, Glyphs (alpha order)
This is an interesting scenario although the genetic "lineage that was clearly European in origin"(haplotype X) turned out to be a dry well.
I'd love to see a good picture of that Cactus Hill point. I've seen a nice museum collection of Solutrean blades and wonder if I could see the similarity.

Origin and Diffusion of mtDNA Haplogroup X
A maximum parsimony tree of 21 complete mitochondrial DNA (mtDNA) sequences belonging to haplogroup X and the survey of the haplogroup-associated polymorphisms in 13,589 mtDNAs from Eurasia and Africa revealed that haplogroup X is subdivided into two major branches, here defined as "X1" and "X2." The first is restricted to the populations of North and East Africa and the Near East, whereas X2 encompasses all X mtDNAs from Europe, western and Central Asia, Siberia, and the great majority of the Near East, as well as some North African samples. Subhaplogroup X1 diversity indicates an early coalescence time, whereas X2 has apparently undergone a more recent population expansion in Eurasia, most likely around or after the last glacial maximum. It is notable that X2 includes the two complete Native American X sequences that constitute the distinctive X2a clade, a clade that lacks close relatives in the entire Old World, including Siberia. The position of X2a in the phylogenetic tree suggests an early split from the other X2 clades, likely at the very beginning of their expansion and spread from the Near East.

The more we learn the less we know.
Thanks. I was hoping for something in English, lol, but I'm slowly working on it.
That does it! Pass the smokes.
The gist is that the original finding (X was euro mtDNA) was the result of a sample size that was too small.
This study has a large sample size from most geographic locations. Result was that they found X in Africa, Europe, Asia and America. To me, the most interesting thing is that Native American haplogroup X is not closely related to any old World sample. They suggest dates for divergence not later than 11,000 ya and no earlier than 25,000 ya.

I don't rule out the possibility that some Halo-X may also have arrived from across the Atlantic.
