Who do you think you are?

My mother is very diligent about ancestry, DNA, family history - so I am a little spoiled in knowing most of my origins or at least what parts of who go where in a family tree.

Mother is British, dad is American but digging deeper than that, and beginning to think of the Paleolithic humans, I want to know more about where I come from and what percentages of which parts of where comprise who I am.

I ordered a DNA test!  From the results of mother's test I already know from where our matriarchal DNA originates, but I want to know more!

I want to know who I am molecularly.  I want to see myself as a framework of math and numbers and see if there's an explanation for the instincts I have.
