Toward more effective paleolgenetic analysis DNA preserved in bones undergoing fossilization deteriorates up to 50 times faster when stored in a museum than when the bones are buried in the ground. This has just been shown by a paleogenetics team led by Eva-Maria Geigl (Institut Jacques Mono / CNRS - Paris). This study, which was published in the Proceedings of the US National Academy of Sciences 8 January 2007, shows that in order to improve the quality of paleogenetic analyses, archeological and paleontological remains should be treated like biological samples both during and after excavation.
