gregladen | December 16, 2013Usually when I mention The Hobbit I'm talking about the hominid, or something related to the hominid, or a book about the hominid. But here I want to point you to something related to the book by Tolkien and, of more immediate importance, about the science of the Hobbit and things related. You've certainly already read this important book about the Science of Middle Earth. But you may not yet have seen this blog post by my friend Matt Kuchta on the geology of the Lonely Mountain.
Like many of you, I saw The Hobbit: The Desolation of Smaug last weekend. Like many of you, I've read "The…

Okay, so we've got lots of increases in brain size, and a few decreases. In the cases where we have decreases, we usually have body size decreases as well. More often than not, we have body size decreases which result in a disproportionately large brain size, but occasionally we have a body size increase which results in a disproportionately small brain size. And all of that brings us to the Hobbit.
The authors looked at Homo floresiensis in relation to the Dmanisi hominids, Homo habilis, and a Homo erectus from Ngangdong and found that if we…
razib | January 26, 2010Is the Hobbit's Brain Unfeasibly Small?:
Brain expansion began early in primate evolution and has occurred in all major groups, suggesting a strong selective advantage to increased brainpower in most primate lineages. Despite this overall trend, however, Mundy and his colleagues have identified several branches/lineages within each major group that have shown decreasing brain and body mass as they evolve, for example in marmosets and mouse lemurs.
According to Mundy, "We find that, under reasonable assumptions, the reduction in brain size during the evolution of Homo floresiensis is not…
