In 2003 a mysterious tiny species of hominin (early human) was discovered on the Indonesian island of Flores. It was given the scientific name Homo floresiensis, but it's better known by its catchy nickname: "the hobbit".
Nothing quite like the hobbit had been observed before in two million years of human evolution. For one, fully grown it was only about 3.5ft (1.1m) tall and would have weighed about 25kg. And, even more unusually, its skull was tiny: the hobbit's brain would have been no larger than a modern chimpanzee's.
