Back in August, I learned about
the Genographic Project, a
genetic genealogical study by the
National Geographic designed to collate DNA samples from people all over the world to build a
migratory map of mankind, essentially to continue proving the hypothesis that every one of us has a genetic heritage that can be traced to
one man in Northern Africa about 60,000 years ago.
I'm not the first Singaporean to participate in the project — I read about one other guy who did it in the papers some time before that, but I was intrigued enough to send in the US$126.50 for the genetic testing kit. The money would be used to fund cultural preservation projects nominated by indigenous populations, the first groups that the Genographic Project had tested, the ones most genetically isolated and thus easier to track, as opposed to the rest of us whose genetic heritage could be wildly mixed up over the millennia.
Anyway, I got the kit, did the cheek swabbing, sent in the samples back to the National Geographic,
and got the results back today. Of course, it's just a generic report — the testing is basically just to place me in a specific
haplogroup — but no real surprises here: my recent ancestors have all been ethnic Chinese, and the trail that traces my genes back to Africa is pretty straightforward.
I'm in
Haplogroup O, with the genetic markers M168 > M89 > M9 > M175. M168 was
my earliest traceable ancestor in Africa about 50,000 years ago, and each marker traces a migratory step (and mutation) ending with M175, which more than half of all Chinese males carry and is widespread in East Asia and in lower frequencies in Tahiti and Indonesia.
The bigger their DNA database, the more refined their results will be, so if you can spare the cash and are interested in how your family got from Africa to where you are now, this might be worth a go — and the money goes to help indigenous peoples, so it's not all that bad. And now I know that my ancestors travelled north from Africa, through the Middle East, through Central Asia and finally settled in China around 35,000 years ago, where the trail ends for now, unless they turn up something new as more results from this region come in.
One thing I didn't know, though: despite generations of my family having lived in Southern China, according to the results my ancestors actually came into Asia from the northern route, so I'm genetically (and patrilineally) more northern Chinese — I don't appear to show the
genetic mutation that marks southern,
Han Chinese. This is not to say I don't have Han Chinese stuff in me, of course; this is just
Y-chromosomal analysis, after all.
All in all, this may not seem like much, but I still think it's way cool, that we carry our genealogy with us, encoded into our very being. And that we really
are all siblings... on the skin or under it.
