Sure looks like some kind of R1b-L21 map to me. I wonder if any of my R2 cousins have red hair? Interesting about three variants and that two are old and one (histidine red) is not. Do they know if there is a relationship between histidine red and L21?
I don't know. I have the tryptophan red variant, and I read in SNPedia that is the most common one in Ireland.
I'm not sure where they came up with that "70,000 years old" stuff. I take all that with a large grain of salt.
