I'm not sure I've ever read a study that was free of errors of this
sort, and I've only ever really paid attention to the R haplotypes.

I think more than half the R-M73 reported in Sengupta et al. were not
R at all. Contu et al.mixed up at least one R1b1a and R1b1b - thus
dramatically overestimating the TMRCA for R1b1a. One of the tables
in Cinnioglu had two STRs transposed. Etc.

Since the journals that publish these papers rarely publish
corrections (or they charge additional fees to read the corrections
when they are published) maybe there is a need for a wiki project of
some sort where corrected supplemental data could be aggregated. I'm
not volunteering to set one up, by the way
