And Now Mitochondrial DNA Miracles

I wrote different times about the project of National Geographic Genographic, where is possible to know where are you coming from. From the beginning of the human existance. It was unpossible that so florant business remains the prerogative only of Nat.Geo. So, if you had not time to do it till today, you can choose between 2 (at least) DNA reading providers. The second you can find here Oxford Ancestors.

Because I'm in this period only on the way to my $300-600 to throw for this research, I did not do it till now. But I have the hope that some later the prices begin to fall down. With growth of the quantity of providers. ;)))

Now to miracles.
Do you know how many children had Adam and Eve? No? I'll tell you now. Not 3 (Cain, Abel and Seth). More. 10 sons and 18 daughters.

And here you have the first miracle:

A new history of Britain and Ireland by Norman Davies, "The Isles," (Oxford University Press) begins with an account of Cheddar man, an 8,980-year-old skeleton from which mitochondrial DNA was recently extracted.

The DNA turned out to match that of Adrian Targett, a teacher in a Cheddar Village school, proving a genetic continuity that, despite numerous invasions, had endured through nine millenniums.

Now the second miracle:

In 1998, Dr. Wallace and his colleagues discovered the X pattern, a rare European lineage, among the northern Native Americans such as the Ojibwa and Sioux. At first they assumed it came from intermarriage with modern Europeans. But the American X lineage turned out to be pre-Columbian and its owners would have arrived in America either 15,000 or 30,000 years ago, depending on certain genetic assumptions.

The European X lineage seems to have originated in Western Asia around 40,000 years ago. Dr. Wallace suggests a part of this group may have made their way to America via Siberia, even though no traces of the X-lineage have yet turned up in eastern Asia. A trans-Atlantic route is a possible alternative.
