Where do Hobbits come from

[The Saucepan Man]

I don't think so. Smeagol and Deagol were ancestors of hobbits, but not exactly hobbits themselves, as I recall.

I don't imagine them to have been that much different, certainly not in physical terms (particularly stature).

As for the development of Men, there was, of course, scope for development in culture. This clearly occured. The Numenoreans developed an advanced society, while some other strains of Man appear to have been less culturally advanced. And the Edain clearly had greater longetivity than others of their race, although that is , I think, attributable to the influence of Eru, through the Valar.

But I just can't see any scope for men who awoke 6 foot tall or more to shrink to 3 foot within two to three thousand years.
