A new method to extract DNA from ancient objects could reveal secrets about the lives of humanity's earliest ancestors. A team of archaeologists and geneticists have used the process to isolate DNA from a deer tooth pendant that's more than 20,000 years old tracing its ownership to a woman from the Stone Age.


RAZOR's Neil Cairns visits an archaeological dig in France and meets Dr. Marie Soressi from the University of Leiden, who helped develop the new method, and hopes it will let her find evidence of Neanderthals and Homo Sapiens living together. Cairns also speaks to Elena Essel and Dr. Matthias Meyer, the geneticists behind the groundbreaking work at the Max Planck Institute for Evolutionary Anthropology in Leipzig.
