CNN says: "Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests ... The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday."
I've been interested in genealogy since around Thanksgiving 2006 and, in this post-modern age, that implies genetic genealogy too. Haven't sprung for a DNA test yet but it is amazing what genetic analysis is leading to. Somewhere I read that all humans can be traced to a single human female via mitochondrial DNA analysis. Will try to find that back.
