LB1 a new species?
LB1's similarity to H. erectus, which is thought to have arrived on Flores by 800,000 years ago, led Falk and her colleagues to an original conclusion. While it is possible, they say, that H. floresiensis was a dwarf species of H. erectus unique to Flores, they offer an alternative hypothesis. H. floresiensis and H. erectus, they suggest, may have shared a common, currently unidentified ancestor, one that had a small brain and a small body. About all anyone seems to agree on is that the hobbit is a fascinating new addition to the puzzle of human origins and that more work, including DNA studies, may help clarify things.
