Just to clarify in case people are trying to relate this to the mutation rate
for STRs: I take that to be the rate for a new SNP appearing somewhere on the
phylogenetic tree they've constructed with a couple of hundred markers. The
SNP state of Y-Adam for those markers can be deduced -- he has the original
value at those locations, and the various mutations have appeared in different
branches/haplogroups.
