Now, for the first time, scientists from the Max Planck Institute for Evolutionary Anthropology developed methods for the enrichment and analysis of nuclear DNA from sediments and applied them to cave deposits source western Europe and southern Siberia dated ancient nuclear approximatelyand 50, years ago.

Thus, the team could ancient nuclear Neanderthal nuclear DNA from cave deposits that contribute with new clues to the population history of Neanderthals. In their paper, the researchers report: "We nuc,ear a population replacement in northern Spain approximatelyyears ago, accompanied by a turnover of mitochondrial DNA. We also identify two radiation events in Neanderthal history during the early part of the Late Pleistocene. Our work lays the ground for studying the population history of ancient hominins from trace amounts of nuclear DNA in sediments. At the Spanish site, the team recovered only one Neanderthal fossilbut Ancient nuclear DNA was found throughout the cave deposits, revealing the replacement of one population by another around thousand years ago.

No doubt, the anciebt DNA analyses of sediments help to investigate the deep human past, but it is important to be careful to avoid the considerable amount of DNA from bears and hyenas, and other mammals. The researchers specifically targeted regions in the genome where they could be confident of isolating ancinet human DNA, and they also designed methods to measure their success in removing non-human DNA. The researchers found that DNA from the sediments was most closely related to genomes retrieved from bones from those sites, giving them check this out in the robustness of their methods.
But only a single Neanderthal toe bone had been found, and it was too small ancient nuclear sample for DNA. Ancient nuclear also: More Archaeology News. The nuclear DNA extracted from the sediments revealed that not one, but two Neanderthal populations had lived in the cave, with the original group replaced by a later group approximately thousand years ago.

At Chagyrskaya Cave, earlier archaeological studies had suggested that the Neanderthal occupants belonged to a single population, and lived there for only a short time. But as previous work had only recovered a single genome from one nucleat the bones found at the site, there was no way to tell if it was representative of the whole population that lived around Chagyrskaya Cave.
