Can you show where either citation suggests that "the neanderthal species was superior to homosapiens in almost every respect"? In fact, one of the links specifically says:
Quote:
"The fact that Neandethals could adapt to new conditions and innovate shows that they are culturally similar to us," Riel-Salvatore said. "Biologically they are also similar. I believe they were a subspecies of human but not a different species."
As for brain size, Neanderthals are believed to have had a slightly larger brain, but keep in mind that a larger brain does not necessarily mean "more intelligent". If it did, then men would be, on average, more intelligent than women and instead of IQ tests, we would merely need to measure the volume of individual brains.
According to Mountcastle, Vernon B, Perceptual Neuroscience The Cerebral Cortex, 1998, Harvard University Press, the volume of modern man's brain is about 1434 cubic cm and of women's brain is about 1325 cubic cm while Neanderthal's was about 1470 cubic cm. That isn't an appreciable difference. Furthermore, from the book:
Quote:
There is considerable variation in brain sizes in normal adult humans, as shown in Table 2-2, taken from the recent studies of Filipek et al. (1994), made with a 3D magnetic resonance imaging scanning technique. It is not known whether these differences are due to differences in neuron or glial cell numbers, cell sizes, elaborations of the neuropil, etc. What is clear is that there is no well-established causal or even correlative relation between individual brain sizes in modern men and their degrees of intellectual or artistic achievement -- given at least a size within the normal range. Several widely quoted cases of individuals with very large brains and great achievements are matched by equal numbers of individuals of equally great achievement and modestly sized brains. There is no reliable evidence for differences in brain sizes between the several races of modern man (Tobias, 1981a,b). It would be possible with modern imaging methods to seek for long-term correlations between brain size, determined intermittently throughout life, and life accomplishments.
Table 2-2 referenced in the above quote shows a minimum adult brain size of 1173.3 cubic cm and a maximum of 1625.6 cubic cm as measured by Filapek et al.
