In earlier posts, I discussed how I have used an analysis of my Y chromosome DNA to identify my paternal ancestors all the way back to Y-chromosomal Adam, the most recent common ancestor of all men alive today. The following map summarizes my Y haplogroup ancestors from Y-chromosomal Adam down to those who left Africa around 70 thousand years ago (70 kya) and headed east through India and South East Asia and then up through China into ice age Siberia and then across to the Ukrainian steppeland north of the Black Sea.
I was originally going to continue this story all the way across Europe to the Iberian Peninsula and up to Ireland and Scotland, but I will keep that for a later post. I have discovered that there is an immense amount of recent research on European Bronze Age genetics and migrations and a very considerable unfinished debate on how to interpret the evidence. So it may take me a little while to come to grips with it. (A follow-up post is now available at my-paternal-ancestors-european-journey-the-caspian-steppes-to-celtiberia)
