'Hobbit' skull study: species not human

In a an analysis of the size, shape and asymmetry of the cranium of Homo floresiensis, Karen Baab, a researcher in the Department of Anatomical Scienes at Stony Brook University, and colleagues conclude that the fossil, found in Indonesia in 2003 and known as the 'Hobbit,' is not human. They used 3-D shape analysis to study the LB1 skull of the hobbit and found the shape of the skull to be consistent with a scaled down human ancestor but not modern humans. Their findings, reported in the current online edition of the Journal of Human Evolution, add to the evidence that the hobbit is a new species.

The question as to whether the hobbit was human or another species remains controversial. Some scientists claim the hobbit was a diminutive human that suffered from some type of disease that causes microcephaly, which results in abnormal growth of the brain and causes the cranium to be much smaller than the normal human cranium. But Dr. Baab and co-author Kieran McNulty, Professor of Anthropology at the University of Minnesota, believe their findings counter the microcephaly theory. "The overall shape of the LB1 skull, particularly the part that surrounds the brain (neurocranium) looks similar to fossils more than 1.5 million years older from Africa and Eurasia, rather than modern humans, even though Homo floresiensis is documented from 17,000 to 95,000 years ago," explains Dr. Baab.
