A new study freely available online throws into doubt the genomic sequences extracted from Neanderthal remains in two previous articles.
Inconsistencies in Neanderthal genomic DNA sequences
Jeffrey D. Wall, Sung K. Kim
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.
