Should Hitler's DNA have been studied – or just left alone?

>Painstaking scientific testing by a team of international experts has been able to debunk a rumour on whether Hitler had Jewish ancestry (he didn't)

I've been running about the place defending the BBC in other comments, but maybe they could manage not to uncritically accept racial essentialism in an article about Hitler.
