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.
The discovery raises obvious questions about the diversity of the human family, such as whether undiscovered human-like species might survive today. Are we really the sole human custodians of our planet? Could the existence of Homo floresiensis rehabilitate persistent rumours of undiscovered human-like species elsewhere, notably the orang pendek of Malay folklore? Could cryptozoology come in from the cold?
Maybe all those stories and sightings of little hairy wildmen in the area are true.
