Homo floresiensis

I still find this discovery very fascinating. IMO there hasn’t been nearly enough publicity about the story. The little dudes are barely 1 meter tall with brains that are 1/3 the size of ours! Freaky.I realize that there are many examples of miniaturization in nature and that it is an adaptation to isolated island conditions. But this begs a question I have for the life science experts which may be fodder for another thread, but I’ll ask it anyway; how low can they go?I mean, are there practical limits to miniaturization that would tend to arrest the process? Is it conceivable, given the right evolutionary conditions, for a human species to be 1 foot tall with heads the size of walnuts?

hehehe maybe so, but of course the proportions of a rugrat are quite different from that of an adult (human that is). Baby heads are large in comparison to their body size as easily seen in my avatar.(BTW, I almost cropped just the head for use as an avatar when I joined this forum, but I couldn't decide on a suitable background)But these 'hobbits' seem to have fully adult proportions. So is there a practical limit to the reduction in the size of a species?
