A new study of a Neanderthal child's skeleton has suggested that Neanderthal brains developed more slowly than previous studies had indicated:
A new study shows that Neanderthal brains developed more slowly than ours. An analysis of a Neanderthal child's skeleton suggests that its brain was still developing at a time when the brains of modern human children are fully formed. This is further evidence that this now extinct human was not more brutish and primitive than our species. The research has been published in the journal Science.
Until now it had been thought that we were the only species whose brains develop slowly. Unlike other apes and more primitive humans modern humans have an extended period of childhood lasting several years. This is because it takes time and energy to develop our large brain. Previous studies of Neanderthal remains indicated that they developed more quickly than modern humans - suggesting that their brains might be less sophisticated.
But a team led by Prof Antonio Rosas of the Museum of Natural Sciences in Madrid found that if anything, Neanderthal brains may develop more slowly than ours. "It was a surprise," he told BBC News. "When we started the study we were expecting something similar to the previous studies," he told BBC News.

Well, it says what you say it says, but I don't find it convincing. I'm rather certain that larger (not fatter, larger) women have larger babies...assuming that the mothers are healthy and well-nourished. Any other result would be sufficiently unexpected to require rather strong evidence, which that article doesn't supply. (It supplies suggestive evidence, and talks about different measurements being used in different places.)
It also didn't address the grand-parent's claim about the rate of hardening of the bones of the skull, which would be extremely significant if it could be either substantiated or rejected...and which I find dubious, but not impossible.
