The discovery: The bones of a human dwarf species marooned on the remote Indonesian island of Flores between 95,000 and 12,000 years ago while modern humans rapidly developed elsewhere.
Best specimen: One tiny adult female, measuring about 3 feet tall.
Implications: Flores Man smashes the conventional wisdom that modern humans began to crowd out other upright-walking species 160,000 years ago.
Skeptics: Some researchers say Flores Man doesn't belong in the genus Homo at all, even if it was a recent contemporary.

(AP) -- In a breathtaking discovery, scientists working on a remote Indonesian island say they have uncovered the bones of a human dwarf species marooned for eons while modern man rapidly colonized the rest of the planet.

One tiny specimen, an adult female measuring about 3 feet tall, is described as "the most extreme" figure to be included in the extended human family. Certainly, she is the shortest.

This hobbit-sized creature appears to have lived as recently as 18,000 years ago on the island of Flores, a kind of tropical Lost World populated by giant lizards and miniature elephants.

She is the best example of a trove of fragmented bones that account for as many as seven of these primitive individuals. Scientists have named the new species Homo floresiensis, or Flores Man. The specimens' ages range from 95,000 to 12,000 years old.

"So the 18,000-year-old skeleton cannot be some kind of 'freak' that we just happened to stumble across," said one of the discoverers, radiocarbon dating expert Richard G. Roberts of the University of Wollongong in Australia.

Flores Man was hardly formidable. His grapefruit-sized brain was about a quarter the size of the brain of our species, Homo sapiens. It is closer in size with the brains of transitional prehuman species in Africa more than 3 million years ago.

Yet evidence suggests Flores Man made stone tools, lit fires and organized group hunts for meat.

Just how this primitive, remnant species managed to hang on and whether it crossed paths with modern humans is uncertain. Geologic evidence suggests a massive volcanic eruption sealed its fate some 12,000 years ago, along with other unusual species on the island.

Still, researchers say the perseverance of Flores Man smashes the conventional wisdom that modern humans began to systematically crowd out other upright-walking species 160,000 years ago and have dominated the planet alone for tens of thousands of years.

And it demonstrates that Africa, the acknowledged cradle of humanity, does not hold all the answers to persistent questions of how -- and where -- we came to be.

"It is arguably the most significant discovery concerning our own genus in my lifetime," said anthropologist Bernard Wood of George Washington University, who reviewed the research independently.

Discoveries simply "don't get any better than that," proclaimed Robert Foley and Marta Mirazon Lahr of Cambridge University in a written analysis.

To others, the specimen's baffling combination of slight dimensions and coarse features bears almost no meaningful resemblance either to modern humans or to our large, archaic cousins.

They suggest that Flores Man doesn't belong in the genus Homo at all, even if it was a recent contemporary.

"I don't think anybody can pigeonhole this into the very simple-minded theories of what is human," anthropologist Jeffery Schwartz of the University of Pittsburgh. "There is no biological reason to call it Homo. We have to rethink what it is."

Details of the discovery appear in Thursday's issue of the journal Nature.

Researchers from Australia and Indonesia found the partial skeleton 13 months ago in a shallow limestone cave known as Liang Bua. The cave, which extends into a hillside for about 130 feet, has been the subject of scientific analysis since 1964.

Near the skeleton were stone tools and animal remains, including teeth from a young Stegodon, or prehistoric dwarf elephant, as well as fish, birds and rodents. Some of the bones were charred, suggesting they were cooked.

Excavations are continuing. In 1998, stone tools and other evidence were found on Flores suggested the presence 900,000 years ago of another early human, Homo erectus. The tools were found a century after the celebrated discovery in the 1890s of big-boned H. erectus fossils in eastern Java.

Now, researchers suggest H. erectus spread to remote Flores and throughout the region, perhaps on bamboo rafts. Caves on surrounding islands are the target of future studies, they said.

Researchers suspect that Flores Man probably is an H. erectus descendant that was squeezed by evolutionary pressures.

Nature is full of mammals -- deer, squirrels and pigs, for example -- living in marginal, isolated environments that gradually dwarf when food isn't plentiful and predators aren't threatening.

On Flores, the Komodo dragon and other large meat-eating lizards prowled. But Flores Man didn't have to worry about violent human neighbors.

This is the first time that the evolution of dwarfism has been recorded in a human relative, said the study's lead author, Peter Brown of the University of New England in Australia.

Scientists are still struggling to identify it's jumbled features.

Many say that its face and skull features show sufficient traits to be included in the Homo family that includes modern humans. It would be the eighth species in the Homo category.

George Washington's Wood, for example, finds it "convincing."

Others aren't sure.

For example, they say the skull is wide like H. erectus. But the sides are rounder and the crown traces an arc from ear to ear. The skull of H. erectus has steeper sides and a pointed crown, they said.

The lower jaw contains large, blunt teeth and roots like Australopithecus, a prehuman ancestor in Africa more than 3 million years ago. The front teeth are smaller than modern human teeth.

The eye sockets are big and round, but they don't carry a prominent browline.

The tibia in the leg shares similarities with apes.

"I've spent a sleepless night trying to figure out what to do with this thing," said Schwartz. "It makes me think of nothing else in this world."

    I have not been on your site for a quite a few weeks, but your comments are very discouraging. Why do you always refer to Republicans (or as you say "Re puke licans") as mind numbed, ignorant, simple minded people? There are over 300,000,000 people in the great U.S of A. How can you say that 150,000,000 USA citizens are all ignorant? How can you say that Okies are all "Red Neck"? Most of the patrons at Hudstone's have advanced degrees and are professionals. They have experienced skills in both life and personal experiences. How can you say Okies are "Red Neck" when most Okies are not from Oklahama? How come you assosiate all people that you meet in OKC, that do not agree with you, as "Red Necks"? How come you are spending so much time trying to figure out who is mad at you instead of figuring out why they are mad at you? Evidently this is not just a problem at just Hudstone's, but at other places too. Why do you edit my responses so you can address only the questions or comments that you choose? My last question is, why do you think, or assume, that everyone that disagrees with you is either a NAZI, a rich person, or a Replubican? I will just let you know that I am a very well educated 33 year old Cheese Head transfered poor boy that lives here now. I am not a Red Neck. I just make educated decisions.

  2. I do respond to your comments and as of yet, I have not censored any of your comments. I chose to respond to them and each section of the generally well written comments. When I have the chance, I will respond in full to your comment in a post.
