A different species of homo walked this earth as recently as 18,000 years ago, long after Homo habilis, Homo erectus, even 10,000 years after the Neanderthals had died out. Homo floresiensis, otherwise known as the Little Lady of Flores, is definitely shaking everyone's family tree. The discovery of this tiny human species, who lived on the island of Flores in Indonesia at the same time our own ancestors were colonising the world, basically rewrites the book on what we know of human evolution. From other discovered remains, scientists say this little "hobbit" shared its island with a large rat, giant tortoises, a dwarf species of Stegodon (an extinct pygmy elephant), and Komodo dragons. Sophisticated stone tools and evidence that these tiny humans may have originally arrived on the island by boat have also surprised scientists given the human's small brain, similar in size to a chimpanzee. Since the bones of the seven discovered Flores humans are not fossilised, scientists are hoping to be able to use DNA to answer questions about their genetic link with surviving humans.
