Island 'Hobbits' Separate Human Species

Separate species may have evolved from homo erectus

(Newser) – Two new reports forward the theory that the tiny people who roamed an Indonesian island 8,000 years ago were a separate species of human, the BBC reports, not just pygmy versions of homo sapiens. The biggest clue is the feet of the “hobbits,” which are distinctly primitive but human. Scientists say the 3-foot-tall creatures must have branched off the human line before the modern foot evolved.

The homo floresiensis species appears to descend from a prehistoric human species, like homo erectus, that arrived at the isle more than a million years ago and then shrank, researchers say. The second study, which analyzed small-brained pygmy hippos isolated from mainland ancestors, concludes that the hobbits may have similarly evolved smaller brains—one-third the size of a human’s—in isolation.

It could be that H. floresiensis' skull has become dwarfed from living on an island, rather than being an abnormal individual or separately-evolved species. - Eleanor Weston, London

Were 'Hobbit Humans' Eaten by Giant Storks?

Bones of tiny people found in gathering spot of 6-foot birds

(NEWSER) - The remains of hobbit-sized humans in a gathering area of extinct giant storks is leading scientists to conclude that man may have once been bird food. The carnivorous 6-foot-tall Leptoptilos robustus stork, among the largest bird to ever walk the earth, was likely a "ground-bound hunter, as its bones were thick," says Smithsonian researcher Hanneke Meijer. The predator could have fed on fishes, lizards and birds, "and possibly even small, juvenile hobbits," she adds. "These birds are opportunistic carnivores—if you give them plenty of prey items, they'll hunt all of them." More»

Forensic artist reconstructs face of first modern human found in Europe

(NEWSER) - Meet the first modern European. His face—or hers, as researchers have been unable to determine the sex—was reconstructed by a forensic artist based on a partial skull and jawbone discovered in a Romanian cave. The facial features linked to the 35,000-year-old bones recall the continent's immediate African ancestors, reports the Guardian. Scientists speculate the skin color was darker than present-day Europeans. More»

'Hobbit' Fossils Mesmerize Scientists

Number of supporters grow for 'distinct' hominid species theory

(NEWSER) - Six years after their discovery on an Indonesian island, fossils of 3-foot-tall people creatures nicknamed "hobbits" continue to captivate researchers, reports the New York Times. So far, they haven't been clearly linked to other known human fossils. They may be descendants of Homo erectus who migrated from Africa earlier, or perhaps are an example of "reverse evolution," posit researchers. Some critics believe they are dwarf mutants or suffered a brain-shrinking disease that gave them grapefruit-sized heads. More»

'Hobbits' Were Just Short on Food: Scientists

Others say Indonesian remains were dwarfish new species

(NEWSER) - In a new volley in the back and forth over whether "hobbit" fossils found on an Indonesian island were a separate species, a research team says the remains are those of modern humans suffering from malnutrition-induced dwarfism. Iodine deficiency during pregnancy can result in humans growing less than 3 feet tall—and looking similar to the fossils found in Indonesia, the BBC reports. More»

'Hobbits' Were, Indeed, a Different Kind of Human

Wrist-bone analysis shows link to apes

(NEWSER) - A new study of three wrist bones from an 18,000-year-old fossil shows that the so-called hobbits of Indonesia were, indeed, a separate human species. When the bones were discovered in 2003, scientists trumpeted the find as evidence of a smaller species, Homo floresiensis. But skeptics argued that the hobbit, at 3 feet tall with a brain the size of a grapefruit, was in fact a human afflicted by microcephaly, a brain-shrinking disorder. More»
