 In 2006, two research teams working on the same Neanderthal sample published their results, Richard Green and his team in "Nature", and James Noonan's team in "Science".The results were received with some scepticism, mainly surrounding the issue of a possible admixture of Neanderthals into the modern human genome.In 2006, Richard Green's team had used a then new sequencing technique developed by 454 Life Sciences that amplifies single molecules for characterization and obtained over a quarter of a million unique short sequences ("reads").
