New method rescues DNA from contaminated Neandertal bones

Retrieval of ancient DNA molecules is usually performed with special precautions to prevent DNA from researchers or the environment to get mixed in with the DNA from the fossil. However, many ancient fossils have been lying in museum collection for decades, and are contaminated with present-day human DNA before they enter the DNA-laboratory. A new method provides a solution to this problem. [...] sciencedaily.com
