Is it nature that defines me?

The old nature or nurture debate, but let's take a dive

Nature is all about genes

Currently one can have his DNA tested to learn about his haplogroup, that in turn can trace fore-father's or fore-mother's journey over thousands of years. At least this is what National Geographic’s Genographic Project promises. And
There is a body of evidence that the human tree is more like a sea with currents, mixing modern humans (homo sapiens sapiens) with more than one archaic species and has tides that go back and forth between continents. For a non-standard view of human DNA research, I recommend Dienekes Anthropology Blog. I postponed the decision to take such a test until these tests catch up with research.

In the mean time I can look at my country DNA statistics and see the gene pool in which mine originated. A well documented site for this is eupedia.com, where Y DNA (male haplogroup) tables per region help one see how neighboring countries are often genetically similar:

As I'm tall, having fair complexion and no dark eyes, it seems no "accidents" happened in recent times. So I fit in the population of any temperate European country, neither too close to Mediterranean Sea, to get sunburns, nor too close to the Arctic Circle as my long limbs are not well adapted for that climate.

One can learn a lot about himself by looking at his family tree. With help from several family members I built one using www.ancestry.com going back to around 1800. What I learned is that they were usually city dwellers and most of my grand/.../fathers were priests or merchants while my grand/.../mothers were often teachers.

Another important aspect I learned is where they used to live. My father's family was to be found near Dniester river, halfway between its source and the Black Sea. On my mother's side, they were south of the place Carpathian Mountains take a 90 degrees turn (from East-West to North-South), in the closest point these mountains get to the Black Sea (less than 200 km). Great place for vineyards, but this is another story. 
I chose not to name current localities, as in the last 200 years, names and borders changed so often in the region.

About nurture in the next post.

Who am I?

Next to "What's my purpose in the world?", it's one of those existential questions that kept me up at night.

Let's look at the facts:

• I'm a Romanian citizen;
• I live in Romania;
• Romanian is my mother-tongue;
• I am of Eastern Orthodox denomination.

There's nothing odd about me, is there?

But who am I, really?
