Have at it folks...

Thanks. For those of us who follow this stuff, this is big!

One implication is that the rate of change in mitochondrial DNA is probably faster than used in in the original calculations for Eve's age. Meaning the original estimate was too far back. Which would mean we are far younger (as a species) than we thought.

Too bad. It was such a nice concept.

Damn--I guess I'll have to go back to being a European-American and not qualified for preferences! Damn, Damn, Damn!

BTW, where are all the evilutionists, er evolutionists tonight? No comment from the peanut gallery tonight? Geesh, here I thought they really knew their stuff (LOL).

I watched a Show on PBS about using markers on the Y chromosome of males to track migration patterns out of Africa.

Earliest peoples found living today were the African Bushmen (Click-Talkers) and the most recent were the American Indians.

The arguments made were compelling.

A Blast from the Past.

Fathers can be influential too
by Eleanor Lawrence

Biologists have warned for some years that paternal mitochondria do penetrate the human egg and survive for several hours... Erika Hagelberg from the University of Cambridge, UK, and colleagues... were carrying out a study of mitochondrial DNAs from hundreds of people from Papua-New Guinea and the Melanesian islands in order to study the history of human migration into this region of the western Pacific... People from all three mitochondrial groups live on Nguna. And, in all three groups, Hagelberg's group found the same mutation, a mutation previously seen only in an individual from northern Europe, and nowhere else in Melanesia, or for that matter anywhere else in the world... Adam Eyre-Walker, Noel Smith and John Maynard Smith from the University of Sussex, Brighton, UK confirm this view with a mathematical analysis of the occurrence of the so-called 'homoplasies' that appear in human mitochondrial DNA... reanalysis of a selection of European and African mitochondrial DNA sequences by the Sussex researchers suggests that recombination is a far more likely cause of the homoplasies, as they find no evidence that these sites are particularly variable over all lineages.
