WDYTYA? Live presentation on identifying human remains of soldiers who fell during the Great War

Another post on YouTube of a first class presentation from the DNA Lectures at Who Do You Think You Are 2014. This one, given by media savvy Andrew Robertshaw, somewhat ironically, emphasizes that DNA (mitochondrial), when used at all, is often only supplementary evidence. The presentation with questions runs for just over one hour, with a long tail of extraneous material. See it at http://youtu.be/MPupX-d4s74
