October 15, 2007 -- Were Neanderthals direct ancestors of contemporary humans or an
evolutionary side branch that eventually died out?
This is one of the enduring questions in human evolution as
scientists explore the relationship of fossil groups, such as
Neanderthals, with people alive today. Two recent papers describing the
sequencing of Neanderthal nuclear DNA from fossil bone held promise for
finally answering this question [1, 2].
However, the two studies came to very different conclusions
regarding the ancestral role of Neanderthals. Jeffrey D. Wall and Sung
K. Kim from University of California San Francisco now reveal in PLoS
Genetics what they found when they reanalyzed the data from the two
Wall and Kim's reanalysis reveals inconsistencies between them and
they believe that possible contamination with modern human DNA and/or a
high rate of sequencing errors compromised the findings of one of the
original Neanderthal DNA studies.
The authors therefore recommend that we carefully evaluate published
and future data before arriving at any firm conclusions about human
