It's a big deal in that sense, he said, but the combination of characteristics doesn't necessarily indicate interbreeding between populations.
Overall there is no strong evidence for mixing of Neanderthal and modern human populations and "this doesn't add any," said Potts, who wasn't part of the research team.
None of the features cited as unusual in modern humans is exclusively Neanderthal, Potts said. Rather, they could be features passed down from earlier populations in Africa.
The field work that uncovered the skull was conducted in 2004 and 2005.
Meanwhile, a research team led by Svante Paabo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, is trying to map the Neanderthal genome in hopes of better understanding any possible relationship to modern people.
The research was funded by the U.S. National Science Foundation, the Wenner-Green Foundation, Washington University, the Leakey Foundation, the Portuguese Institute of Archaeology, the Royal Belgian Institute of Natural Science, the Romanian National Council for Academic Research and the Foundation Fyssen.
