A comprehensive study of the bones of Homo floresiensis, nicknamed the "Indonesian hobbits" due to their miniscule stature, has revealed that they are not an ancestor of humans at all. Rather, they are an sister-species of Homo habilis, tool-using hominids that went extinct more than 2 million years ago. The study debunked the theory though anthropological examination and statistical modeling of the skull, jaws, arms, legs and shoulders of the hobbits. "The analyses show that on the family tree, Homo floresiensis was likely a sister species of Homo habilis. It means these two shared a common ancestor," said Debbie Argue of the Australian National University School of Archaeology & Anthropology to Phys.org. "It's possible that Homo floresiensis evolved in Africa and migrated, or the common ancestor moved from Africa then evolved into Homo floresiensis somewhere." At only 3.5 feet in height, the hobbits were first discovered in 2003 on the island of Flores in the Indonesian archipelago.
