The brain size of the floresiensis skull is extraordinarily small, at 380cc. This is as small as any australopithecine ever discovered, and fairly typical for a chimpanzee. (Chimps range from about 300 to 500cc, averaging about 400cc, but are physically bigger than floresiensis.) This is smaller than would be expected even for a dwarf form of Homo erectus, and suggests there was active selection for a small brain size for some reason. (Human pygmies, incidentally, are nothing like H. floresiensis; their brains are almost as large as those of normal-sized humans)
mauromongiat on 09 Dec 11The homo floriensis Would be a small human if it did'nt have such a small brain. The fact that the brain of the homo floriensis is so small is a proof that it is a different specie from the homo sappien.
