"Hobbit" Humans Were Diseased, Not New Species, Study Says

May 18, 2006

The "hobbit" humans that lived on the Indonesian island of Flores some 18,000 years ago were actually a population of modern humans stricken with a genetic disease that causes small brains, a new study says.

The argument is being made by a group of scientists who have analyzed all the scientific evidence presented so far about the evolution of the proposed species Homo floresiensis.

The discovery of the hobbit-like humanŚso-called for their small statureŚwas first announced in 2004 after a fossil skull and bones of several individuals turned up on Flores.

Preliminary analysis of the remains pegged them as belonging to a totally new species (see hobbit fossil photos).

But gaps in the understanding of how these people existed alongside modern humans and came to wield sophisticated stone tools are coming under greater scrutiny.

In a comment appearing in tomorrow's issue of the journal Science, researchers challenge the evidence used to rule out the notion that hobbits were modern humans with a disease known as microcephaly.

This genetic disorder causes smaller brain size in modern humans and can also lead to short stature.
