Researchers Develop Method for Distinguishing Ancient Human DNA from Modern Day Contaminants | GenomeWeb Daily News | Sequencing | GenomeWeb
"NEW YORK (GenomeWeb News) – Researchers from the Max Planck Institute for Evolutionary Anthropology and the Russian Academy of Sciences have come up with a way to overcome modern human DNA contamination — a major obstacle in past ancient human DNA sequencing efforts....

Based on the DNA patterns present in mitochondria, the researchers concluded that the Russian remains are roughly 30,000 years old — in the same range as previous estimates that put the skeleton's age at between 30,000 and 33,000 years old....

The team is currently trying to collect more samples from early modern human populations. And the new method may have applications for studies of historical population patterns throughout Europe and elsewhere, Krause explained, such as the effects of an ice age occurring in Europe around 20,000 years ago."
