Chris Stringer skeleton

Professor Chris Stringer talks to the media about the discovery of a new species of human living (left skull) on the Indonesian island of Flores as recently as 18,000 years ago during a press conference in central London. The discovery of the partial skeleton, with the skull placed here next to that of a modern-day human (right), came at a cave site called Liang Bua and belonged to an individual who, while fully adult, was barely a metre tall and had a skull the size of a grapefruit.
