The researchers say they are now more convinced than ever that Homo floresiensis represents a distinct species and not some diseased individual of modern human (Homo sapiens)as some sceptics have suggested.
"The finds further demonstrate that LB1 is not just an aberrant or pathological individual but is representative of a long-term population," they write in Nature.
A critical line in their argument is the length of time which the new collection of remains represents - possibly 80,000 years - making a disease explanation for the cause of the little people's stature and shape an unlikely one.
The team contends that Homo floresiensis, with its 380-cubic-cm-sized brain, is the outcome of a phenomenon known as endemic or island dwarfing.
This sees isolated species, released from the pressures of predation but constrained by limited resources, evolving either smaller or larger forms than would otherwise be the case.
