Pretty sloppy, FM. There is no such thing as "Solutrean MtDNA" (and i'm not saying you said there is). There is ancient European MtDNA, but Solutrean is just the name of an h.s.s. culture which describes cultural artifacts found in what is now southwest France and northeast Spain. It is by no means a term which can be applied to everyone living in Europe 24,500 years ago. In fact, the current archaeological thinking is that the Solutrean culture flourished from about 22,000 ybp to about 17,000 ybp. Additionally, one of the objections to the Solutrean hypothesis is the significant difference in technique between Clovis points and Solutrean points. I've brought that up in these fora before. Solutrean pressure flake technique involved removing the spalls on a line perpendicular to the long center-line of the point. A most distinctive feature of Clovis technique is that the spalls are removed on a line diagonal to the long center line.
While there have been some Clovis points found with perpendicular spalling, and some Solutrean with diagonal spalling, the images above show the characteristic
spall lines of these points.
I am not heavily invested in the Solutrean hypothesis, and there are many cogent objections to it. There are also may questions which have been asked in support of it which have not been well answered. Your comments here are irrelevant, as the Solutrean culture
did not exist 24,500 years ago. Furthermore, the land bridge hypothesis cannot account for the extraordinarily high percentage of ancient European MtDNA in Amerindians of eastern Canada--about 25% as compared to 3% for the entire rest of the Amerindian population of the two continents (according to a Canadian geneticist). It also doesn't account for the finds of bi-facial, pressure flake points found in Pennsylvania and Virginia which have been dated to 14,000 ybp or earlier, which is well before the roughly 11,500 ybp of the earliest Clovis points. Largely, i enjoy the spectacle of academic bitch fights over intellectual turf.
While certainly interesting, i see no connection between the find you are reporting and the Solutreans or the producers of Clovis technology.
