More Evidence For Hobbit Sized Species
GogglesPisano writes "CNN.com reports that scientists digging in a remote Indonesian cave have uncovered a jaw bone that they say adds more evidence that a tiny prehistoric Hobbit-like species once existed." From the article: "The discovery of a jaw bone, to be reported in Thursday's issue of the journal Nature, represents the ninth individual belonging to a group believed to have lived as recently as 12,000 years ago. The bones are in a wet cave on the island of Flores in the eastern limb of the Indonesian archipelago, near Australia."
Not knowing the data that well, midgets and dwarfs seem to make up only a very small proportion of the population. If you sampled 100 people, what is the chance that you will get one diminutive person, let alone 20? The more skeletons they find that are similarly proportioned, the less likely it is that they represent statistical outliers, and the more likely it is that they represent the norm. Given the number of skeletons that have been found, I find the argument that they are statistical outliers to be unconvincing (though still possible, I suppose). A more likely explanation is that the small skeletons represent a significantly different population, whether it be an isolated group of Homo erectus, or an offshoot of the Home erectus line.
