Problems with Neandertal DNA sequence data

The implications are somewhat ambiguous, but it suggests that we should avoid any hasty conclusions from ancient DNA sequence.

Inconsistencies in Neanderthal genomic DNA sequences

Jeffrey D. Wall, Sung K. Kim

PLoS Genetics Early Online Release
Two recently published papers describe nuclear DNA sequences that were obtained from the same Neanderthal fossil. Our reanalyses of the data from these studies show that they are not consistent with each other and point to serious problems with the data quality in one of the studies, possibly due to modern human DNA contaminants and/or a high rate of sequencing errors.

is YOUR analysis of the research available?

no, I haven't looked into it in very much detail. I'd suggest looking at John Hawks' weblog. I think he went into some detail about it...good luck.
