The ‘petrous bone’ is an inelegant but useful chunk of the human skull — basically it protects your inner ear. But that’s not all it protects. In recent years, genetic scientists working to extract DNA from ancient skeletons have discovered that, thanks to the extreme density of a particular region of the petrous bone (the bit shielding the cochlea, since you ask), they could sometimes harvest 100 times more DNA from it than from any other remaining tissue.
Now this somewhat macabre innovation may well resolve one of the most heated debates about the history of India.
