My Genetic Journey (Part 2)

About a year and a half ago, I got a kit from National Geographic's Genographic Project to determine my paternal "deep ancestry", and I talked about the results here.

This year I got a kit to do my maternal line, through mitochondrial DNA, and the results are depicted below:



No real surprise: I am a member of haplogroup H, the most common mitochondrial haplogroup in Europe. My great-grandmother was Emma Hesburn Dean, whose ancestors likely came from England or Ireland. (I don't know more because she was adopted at an early age, and I've been unable to locate her parents, who are said on her death certificate to be Charles Dean and Barbara Hall, in any genealogical records.)

Mitochondrial Eve, the most recent common ancestor (along the female line) of all humans, probably lived about 150,000 years ago in East Africa. From there, mutations in the particular region of mitochondrial DNA suggest the following line of descent: L1/L0 -> L2 -> L3 -> N -> R -> pre-HV -> HV -> H. L3 corresponds to the first humans to have left Africa. N lived in the eastern Mediterranean and western Asia. HV corresponds to Turkey and Georgia. Finally H corresponds to the rise of the Aurignacian culture in Western Europe. H probably arrived in Europe about 30,000 years ago. My maternal ancestors probably lived in England or Ireland for thousands of years before emigrating to the US - perhaps in the 1800's.

My Genetic Journey

For my birthday, I got a kit from National Geographic's Genographic Project. For $99, you can submit a cheek swab and have the DNA of either your maternal or paternal lines analyzed. (Women will have to settle for just the maternal line.)

I had my paternal line done this year; next year, maybe I'll have the maternal line done.

The results are in, and they're not a surprise. I'm a member of Haplogroup E3b1, which, the project says, " is most heavily represented in Mediterranean populations. Approximately 10 percent of the men in Spain belong to this haplogroup, as do 12 percent of the men in northern Italy, and 13 percent of the men in central and southern Italy. Roughly 20 percent of the men in Sicily belong to this group. In the Balkans and Greece, between 20 to 30 percent of the men belong to E3b, as do nearly 75 percent of the men in North Africa. The haplogroup is rarely found in India or East Asia. Around 10 percent of all European men trace their descent to this line. For example, in Ireland, 3 to 4 percent of the men belong; in England, 4 to 5 percent; Hungary, 7 percent; and Poland, 8 to 9 percent. Nearly 25 percent of Jewish men belong to this haplogroup."

Here's how my ancestors are believed to have moved around from about 60,000 years ago to about 20,000 years ago.



Of course, since this data reflects only my father's father's father's .... father, it doesn't tell me about most of my ancestors. But it's still oddly moving to contemplate.

Sadly, some Native Americans are opposed to the Genographic Project, because learning about their ancestry "can clash with long-held beliefs".
