Hobbit species may not have been human

Hobbit species may not have been human

AFTER five years of arguments over the so-called hobbits, the University of New England paleoanthropologist who formally described the tiny new hominin species from the Indonesian island of Flores is facing another wave of controversy.

This time, Peter Brown could raise the ire of some of the scientists who supported him in an academic debate that degenerated into an international scandal.

Brown, who initially placed the species in the human genus Homo and named it Homo floresiensis, is considering stripping the hobbits of their human status.

More remains have been found, and the species is now represented by six to nine individuals, depending on how the partial skeletons are put together. The skeletons range in age from 17,000 to 95,000 years.

And a big body of research, including Brown's own, since the publication of the first papers on the find has forced a rethink of his initial classification.

In a paper accepted for publication in an upcoming special Homo floresiensis edition of the Journal of Human Evolution, Brown and colleague Tomoko Maeda, also of UNE, say the hobbits' lineage left Africa "possibly before the evolution of the genus Homo". (The root of the human family tree stretches back about two million years to Homo habilis, or Handy Man, in Africa.)

Brown says assigning the Flores hominin to a different genus would worry some scholars. "They will think it somehow marginalises Homo floresiensis; that it's a clear statement that it is not a member of our genus, and it's extinct, so we don't have to worry about it any more," he says. "That's nonsense, because it's part of the broader evolutionary story of our species."
