Hi All, The following article contains some fascinating new information about North American prehistoric cultures. Archaeologists have always speculated about the relationships between the Western Stemmed Point Tradition and the Clovis Tradition. It’s nice to finally be able to add another piece to the puzzle, but this new info poses as many questions as it answers. Which is, of course, the fun of archaeology. http://esciencenews.com/articles/2012/07/12/paisley.caves.yield.13000.year.old.western.stemmed.points.more.human.dna Enjoy! Mike and Kathy
