In 2015, the forensic anthropologist, Professor Dame Sue Black, was cast away by Kirsty Young.

Brought up on the west coast of Scotland and in Inverness, she fell in love with biology at secondary school and read Human Anatomy at the University of Aberdeen. After graduation, she worked at London's St Thomas' Hospital as an anatomist, and police began to call on her to help identify bones.

She spoke to Kirsty about the mysteries of the human body.
