gene pools

so i got my dna analysis back from the nat. geographic society's "genographic project" in which my Y chromosome identified me as a member of haplogroup I with markers at M168, M89, and M170, each of which identifies an ancestor who lived, respectively, roughly 50,000, 45,000, and 20,000 years ago, moving from africa, to the middle east, through turkey into the balkans and from there across much of northern europe---some people call M170 the viking gene, but it's also related to celts of central europe---amazing stuff---check out the atlas
