Trash to treasure

As Anna Dhody tells it, sometime in 2000 or 2001 she and her supervisor Steven LeBlanc, director of collections at Harvard's Peabody Museum of Archaeology and Ethnology, were discussing ways to obtain ancient DNA from secondary archeological finds over lunch. Recalling her training as a forensic anthropologist, Dhody, now curator of the Mütter Museum of the College of Physicians of Philadelphia, mentioned how things like cigarette butts or discarded coffee cups from crime scenes often yield DNA. "Why can't we use modern day forensic technology to solve ancient mysteries?" she asked.
