‘Hobbit’ bone from tiny species of ancient humans found on Indonesian island
The remains of the smallest ancient human species, Homo floresiensis, have been found on the Indonesian island of Flores. The fossil arm bone belonged to an adult who roamed the island 700,000 years ago.This species is thought to have shrunk in size due to the unique evolutionary pressures caused by being on the island. A tiny arm bone is similar to previously discovered "hobbit" skeletons, and a newly discovered pair of teeth bears a resemblance to those of Homo erectus. The ancient man was about 100 cm tall, which is 6 cm less than the estimated height of a 60,000-year-old skeleton. Island dwarfism may have helped survive food shortages on the islands and avoid large carnivorous mammals.
Questions about how the ancestors of floresiensis came to be on the island remain unanswered. Stone tools show that the island was inhabited as early as 1 million years ago, but how floresiensis ' ancestors got to the island is unknown.
