Thanks for replying Blam, I didn't realize that this was a three year old thread when I first posted. It may well have been Homo-Erectus although I personally think Aborigines are a more modern type than that. Their morphology is fascinating though.
All the features used to define archaic and extinct humans can be found in someone alive today. My theory is that we are all only one species and that's why these features are still with us today.
The Hobbits are some strange 'humans'. They are thought to be from the Homo-Erectus line.
