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

Groundbreaking DNA analysis of Adolf Hitler's blood has uncovered some extraordinary findings about the dictator's ancestry and possible health conditions.

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) and determine that he had a genetic disorder which affects the development of sexual organs - all from an old blood-stained swatch of fabric.

While clickbait headlines have focused on whether the Nazi dictator had a micropenis and only one testicle, more serious are the findings that his DNA showed very high scores - in the top 1% - for a predisposition to autism, schizophrenia and bipolar disorder.

Does this mean he had these neurological conditions? Absolutely not, say the experts - it's not a diagnosis.

But nevertheless, concerns have been raised about stigmatisation and how ethical the research was, prompting the question - should it have been done at all?
