Did "Hobbits" Really Exist? New Evidence Suggests Yes

By Steve Connor, The Independent. Posted May 14, 2009.

A miniature species of extinct humans, nicknamed "hobbits", possessed unusual anatomical features explained by their complete isolation from the rest of humanity for thousands of years on their remote island home in Indonesia, studies have found.

The tiny people, who grew to an adult height of no more than three feet, astounded scientists in 2004 when a skull and partial skeletons were unearthed from a cave on the island of Flores. Radiocarbon dating suggested that the species, Homo floresiensis, had lived in and around the cave for tens of thousand of years before dying out about 17,000 years ago.

The latest research into H. floresiensis has found that they were flat-footed, long-toed creatures who could walk easily on two legs but would have found it difficult to run at speed. A separate study suggests that their very small heads, which were perfectly in proportion to their bodies, were the evolutionary outcome of living on such a remote island for so long.

Two studies published in the journal Nature also cast further doubt on the idea that the hobbits were ordinary people suffering from some kind of pathological condition, such as microcephaly – when the skull fails to grow normally. Many scientists believe there is now little doubt that the hobbits were indeed a human species who had evolved as a result of island dwarfism, when larger animals gradually become smaller over the generations.

"That evidence has been overwhelming for some time now. Our study provides additional and unequivocal confirmation that we're dealing with a new species. The pathology debate is officially over," said Professor Bill Jungers of Stony Brook University in New York, who led the study into the hobbit's foot bones. "Their big toe was surprisingly short and more similar to a chimpanzee's in relative length than to humans.

"However, like chimpanzees again, the free parts of the lateral toes were relatively very long and the bones within were curved, whereas human toes in this region are short and straight," Professor Jungers said.

The investigation of the hobbit's foot bones also revealed that the miniature humans lacked an arch. In other words, they were flat footed. "They still walked just fine despite having relatively long feet and funny proportions, but they needed to lift their feet a little higher off the ground to clear their toes, possibly by flexing their ankles or knees more. They were designed quite adequately for walking, but were poorly adapted for long-distance running," Professor Jungers said.

A range of small stone tools found alongside the bones suggest that the hobbits hunted and butchered local animals that lived on the island at the time, such as pygmy elephants, giant rats and reptiles, such as the Komodo dragon. But their ancestral origins remain a mystery.

The long toes of H. floresiensis suggest they could be the direct descendants of a hominin similar to an early human ancestor such as H. habilis, rather than the more recent H. erectus, a species known to have migrated out of African long before the migration of our own species, H. sapiens.
