News to Make Creationists’ Heads Explode
I’ve been following the story of the curious “hobbit-like” remains found in Indonesia in 2003 for years with great interest, and today two new studies have been released that conclude this really is a new species of proto-human.
Diminutive humans whose remains were found on the remote Indonesian island of Flores in 2003 truly are a new species, and not pygmies whose brains had shrivelled with disease, researchers reported Wednesday.
Anthropologists have argued, sometimes bitterly, since the discovery of Homo floresiensis — dubbed “the hobbit” due to its size — as to the identity and origins of these distant cave-dwelling cousins. Measuring about a metre (three feet) and weighing in at 30 kilos (65 pounds), the tiny, tool-making hunters may have roamed the island for which they were named as recently as 8,000 years ago. The fossils are about 18,000 years old. …
Two new studies in the British journal Nature go a long way toward settling this debate, even as they raise new quandaries that are sure to stoke further controversy.
A team led by William Jungers of the Stony Brook University in New York tackled the problem from the other end by analysing the hobbit’s foot. In some ways it is very human. The big toe is aligned with the others and the joints make it possible to extend the toes as the body’s full weight falls on the foot, attributes not found in great apes.
But, in other respects, it is startlingly primitive: far longer than its modern human equivalent, and equipped with a very small big toe, long, curved lateral toes, and a weight-bearing structure closer to a chimpanzee’s.
Recent archeological evidence from Kenya shows that the modern foot evolved more than 1.5 million years ago, most likely in Homo erectus. So unless the Flores hobbits became more primitive over time — a more-than-unlikely scenario — they must have branched off the human line at an even earlier date.
For Jungers and colleagues, this suggests “that the ancestor of H. floresiensis was not Homo erectus but instead some other, more primitive, hominid whose dispersal into southeast Asia is still undocumented,” the researchers conclude.
