The article (http://www.chc.org.sg/english/news_bulletin9.cfm) in the The American Journal of Human Genetic states that:

Both the extent and location of the maternal ancestral deme from which the Ashkenazi Jewry arose remain obscure. Here, using complete sequences of the maternally inherited mitochondrial DNA (mtDNA), we show that close to one-half of Ashkenazi Jews, estimated at 8,000,000 people, can be traced back to only 4 women carrying distinct mtDNAs that are virtually absent in other populations, with the important exception of low frequencies among non-Ashkenazi Jews. We conclude that four founding mtDNAs, likely of Near Eastern ancestry, underwent major expansion(s) in Europe within the past millennium...

Hasse,

Thanks for posting that clip from the article. Though I could not access the article from the link (it may have lapsed), I had read the article earlier.

One of the scientists who, I believe, was the lead author on the original scientific paper, Mr. Doron Behar, is an expert on the 'K' line of mtDNA.

Though the K line can be associated with Ashkenazi Jews, it can also be found in many other societies--including in Finland, amongst non-Jews.

And, curiously, the K line is also, as I recall, the haplogroup for the 'Iceman' (the pre-historic body discovered by hikers in the Alps, during a snow-melt, some years back. The Iceman was DNA-tested by one of the leading DNA experts in Britain and was determined to be of the K line.

That only four women are the progenitors of 8million people is a staggering concept, but can probably be said of many other groups, as well. Perhaps even more staggering is that somewhere, very far back in time, all of these people who share the K line had one common female ancestor.

This is a topic we may all want to think about, as it gives true perspective about how we are all related...

Though the science is fascinating (to me), it was your post that reminded me of this aspect of humanity.

I found this article in my file which may be of interest.
