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?
​
My guess is that we couldn't get much smaller than the little rugrat over there in your avatar.

So is there a practical limit to the reduction in the size of a species?
​
I'd say the juvenile cranium represents the smallest a functional human brain can be, so you'd be limited to the body that would be proportional to a brain of that size.
​
But then again, maybe I'm wrong. I'm having a hard time really visualizing the exact size and proportion of Homo floresiensis.
