...He and his colleagues managed to extract DNA from 15 out of 17 pieces of bone or teeth recovered from the Chagyrskaya cave in the Altai mountains in Siberia, Russia. The DNA showed that some pieces came from the same individuals, so the findings represent 11 individuals in total, including several teenagers and children.Dating of sediments and bison bones at the site suggests the Neanderthals lived in the cave between 51,000 and 59,000 years ago, while the DNA shows that many of the individuals were related...Peter thinks it is possible that these individuals all died around the same time, but...

Scientists from the University of Oxford and the University of Manchester have used a new technique, "Zooarchaeology by Mass Spectrometry," or ZooMS, to identify more than 2,000 bone fragments recovered from Russia's Denisova Cave. ZooMS analyzes the collagen peptide sequences in bone, which can then be used to identify its species. Among the remains of mammoths, woolly rhino, wolf, and reindeer, the researchers found one Neanderthal bone. "When the ZooMS results showed that there was a human fingerprint among the bones I was extremely excited. ...The bone itself is not exceptional in any way and would otherwise be missed by...

It was 15 months ago that Science carried a story about the completion of a rough draft of the Neandertal genome. Palaeogeneticist Svante Paabo of the Max Planck Institute for Evolutionary Anthropology in Leipzig was reported as saying "he can't wait to finish crunching the sequence through their computers". It has been quite a long time coming, as it is more than a decade since Paabo first demonstrated it was possible to analyse Neandertal DNA sequences. Earlier reports suggested that Neandertals were sufficiently distinct from humans for them to be classified as a separate species of Homo. The draft genome...

Proposed rankings would classify genomes by completeness and quality.Scientists have proposed classifying genome sequences into six groups, based on their quality.A. Sumner / Science Photo Library Researchers who have mapped a species' genome need to be more explicit about the quality of their sequence, says an international team of genome researchers."People generating these sequences should discriminate a bit more between the products that they provide to the rest of the scientific community," says Patrick Chain of the Joint Genome Institute at the Los Alamos National Laboratory in New Mexico who is first author of a policy paper on genomic standards...

Researchers in Germany said Tuesday they have completed the first high-quality sequencing of a Neanderthal genome and are making it freely available online for other scientists to study. The genome produced from remains of a toe bone found in a Siberian cave is far more detailed than a previous "draft" Neanderthal genome sequenced three years ago by the same team at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. "The genome of a Neanderthal is now there in a form as accurate as that of any person walking the streets today," Svante Paabo, a geneticist who led the...
