I just completed reading the book "A New Human" by Mike Morwood about the 'Hobbits' on the Indonesian island of Flores. It looks like all the noise about the 'Hobbits' having a disease is just BS...a lot of egos involved. I'm particularly disappointed with the 'senior' archaeologist Jacob and Australian Alan Thorne in this whole bruhaha.
Anyway, Morwood thinks the Hobbits and Homo-Erectus have a common anscestor and probably both split from Homo-Habilis. Human artifacts on Flores date to at least 840,000 years ago and the Hobbits lived there at least continuously for 80,000 years, up until about 12,000 years ago.
Morwood also says that the Hobbits share a lot of features with these 1.8 million year old people found in the Republic Of Georgia: Stranger In A New Land (Archaeology)
Morwood also speculates that some of the Asian Homo-Habilis may have 'reverse-migrated' back to Africa at some point in the very distant past arriving there with new habits and capabilities not seen before in Africa. (and then re-emerging later from Africa as Modern Humans)
The plot thickens.
