Carl Zimmer in The Loom:
So let’s recap: It’s been almost eight months now since scientists announced the discovery of Homo floresiensis, the diminutive people that some claim belong to a new branch of hominid evolution and skeptics claim were just small humans. We seem to have entered a lull in the flow of new scientific information about Homo floresiensis. The last thing we heard from its discoverers came in March, when they published scans of the Homo floresiensis braincase, which bolstered their case that the skull they found didn’t happen to belong to someone with a birth defect. The skeptics have made various noises about evidence that the fossils are indeed pathological, and thus can’t be the basis for recognizing a new species. They have told reporters about their visits to pygmies who live near the fossil site on the Indonesian island of Flores. But they have yet to publish any of this in a scientific journal, where their claims could be put to some serious scrutiny. For example, you can’t refute the claim that the fossils are a separate hominid species by showing that living pygmies on Flores are very short. You also have to deal with the odd body proportions of Homo floresiensis, such as its long arms. Perhaps these are pathological too, but no one has gone on the scientific record yet.
