Just curious, I was inspred by
this article on the BBC, where they show a small portion of a genetic tree diagram, and then don't tell me where I can find the whole picture (grrr).
So, I am a Canadian, but my greatgrandparents (father's side) were from England, near London. I believe my mother's family was also from England, and I know that everyone in my immediate family is/was a white anglo-saxon. My girlfriend is Korean, and she has Korean ancestry as far back as she can trace.
Roughly when and where would I have to look to find our common ancestor? Would I have to go all the way back to the place in Africa where all humans came from, or might I find something a little later than that?
