The Official Hobbit Article

23 August 2006 (Proceedings from the National Academy of Science of the United States of America) – The article is finally out (and better yet, it’s on open access!) The article itself is extremely technical, so if you’re not that inclined, check out the related links for a list of summaries (including a new entry from Scientific American).

Pygmoid Australomelanesian Homo sapiens skeletal remains from Liang Bua, Flores: Population affinities and pathological abnormalities

Liang Bua 1 (LB1) exhibits marked craniofacial and postcranial asymmetries and other indicators of abnormal growth and development. Anomalies aside, 140 cranial features place LB1 within modern human ranges of variation, resembling Australomelanesian populations. Mandibular and dental features of LB1 and LB6/1 either show no substantial deviation from modern Homo sapiens or share features (receding chins and rotated premolars) with Rampasasa pygmies now living near Liang Bua Cave. We propose that LB1 is drawn from an earlier pygmy H. sapiens population but individually shows signs of a developmental abnormality, including microcephaly. Additional mandibular and postcranial remains from the site share small body size but not microcephaly.

21 Aug 2006 (Press Release, from EurekaAlert) – Fresh off the press! It turns out that the Indonesian Hobbit, the homo floresiensis, is not a new species of human being but an abnormal variation of ours. Oh well. It was fun to entertain the thought while it lasted. The embargo for this press release was lifted only a few hours ago. Click on the picture link in the actual article to see some cool pictures of the facial symmetry of the hobbit skull.

The skeletal remains found in a cave on the island of Flores, Indonesia, reported in 2004, do not represent a new species as then claimed, but some of the ancestors of modern human pygmies who live on the island today, according to an international scientific team….

One error made in the earlier proposal of a new species was that “comparisons of LB1 were made mostly with Homo sapiens from other geographic areas of the world, principally Europe,” the researchers note. “Yet it would have been logical even for a supposedly novel human species from the Australomelanesian region to have been compared with other human populations, present as well as past, from that region,” they added.

“To establish a new species, paleoanthropologists are required to document a unique complex of normal traits not found in any other species,” says Eckhardt. “But this was not done. The normal traits of LB1 were not unique, and its unusually small braincase was not normal.”

To study LB1’s traits, 94 cranial features and 46 features of its mandible were compared to values for modern humans. All fell within the normal range of variation for Australomelanesians. Two anatomical details, particular grooves in the cranial base singled out as “not seen in modern humans,” in the 2004 new species announcement are, according to Alan Thorne, archaeology and natural history, Research School of Pacific and Asian Studies, Australian National University, Canberra, commonly found in Australian and Tasmanian crania….

To visualize the facial asymmetry, David W. Frayer, professor, department of anthropology, University of Kansas, composed split photographs of LB1’s face, combining two left or two right sides as composite faces. The dissimilarities from the original face and between the two left or right composites were striking. To quantify these differences the researchers compared left and right side measurements on the original face.
