Dear John,
I think Anatole's estimate for R-U152 is pretty close to the true
TMRCA. I just did an intraclade TMRCA estimate using 87 67-marker R-U152
haplotypes and got 3650 using 50 markers and John Chandler's mutation rates
and 3552 using 10 YHRD markers and using YHRD mutation rates. As I have
mentioned previously intraclade TMRCA estimates tend to underestimate the
true TMRCA by some percentage.
Sincerely,
Tim Janzen

My response:

JoGG, 5(2) 217-256 (2009)

R-U152, 184 haplotypes, TMRCA 4125+/-450 years before present.
