Still here stumbling around under the Nut Tree looking at my DNA results from 23and Me. It strikes me that while other blogs are written by experts and offer answers, here I am wandering round watching the questions multiply before my eyes. Why anyone would want to read this mess is beyond me, but thank you so much for stopping by. And if my misery from time to time makes you feel less miserable, then something has been accomplished.
Before I got my DNA test results back I tried to get up to speed on some aspects of the test, and one of them is haplogroup. I found out that haplogroup is a way to think about the great tree of man, or Homo Sapiens. Because I'm female my haplogroup comes down from a very distant woman living about 190,000 to 200,000 years ago now called Mitochondrial Eve. As the great family of woman grew and migrated, the ladies haplogroups grew and migrated. You can see that it's helpful to change the letters at each junction where the tree branches out.
My group, H, can only be given to female descendants because it's contained in the mitochondria of female DNA known by it's abbreviation, mtDNA. Guy haplogroup determination has a whole other set of letters and because there's so much written about yDNA and surname tests, let's let them fend for themselves. H, L2, and A haplogroups belong to us gals.
Science likes to get as specific as possible so the letters break down into sub groups and numbers are added. The haplogroups are also called clads, and the numbers are called subclads. These can be further broken down and if they are then lower case letters are added. While I'm H3 I've seen other people's results that are E1a. And science isn't resting on its laurels. No, researchers are working and these subclads are, even as I write and you read, now breaking down subclads even further in an effort to be as specific as possible. That's great because each addition of a letter or number means deeper specificity, and don't we want that so we can know as much about our deep peeps as possible?
I've had a good time finding out about my H3 haplogroup. We're quite an interesting band of travelers and here's our story. Haplogroup H originated in Southwest Asia about 20,000 to 25,000 years ago on that great big tree of man, er I mean, of women, when H came out of haplogroup HV. You can Google up a haplogroup migration tree if you get a spare moment and are interested.

My H3 deep peeps, after a stint in Southwest Asia, moved on down the line as part of the migration during the last ice age, and landed in the Franco-Catabrian Glacial Refuge. Interestingly for me, this is where all of the cave art also comes from. So can you picture them huddling in caves and what not, enduring the last ice age? If I was there I'd have said, "Hey, let's put some art on those cave walls!" This group was also responsible for repopulating much of Europe after the ice melted.

Well, I could go on here because this is the kind of stuff I just love knowing. But you'll have your own haplogroup to work on and the fun of finding out about your own deep peeps!
