Whether H. floresiensis is correctly attributed to the genus Homo; if actually a member of an earlier member of the hominin lineage, such as H. erectus; could Hobbit belong to A. afarensis and if so how did Honnit's ancestors get to Indonesia; these are all questions difficult to answer on the evidence currently available.

For now, the Mata Menge fossils seem to expand the timeframe of H. floresiensis and confirm it was a distinct species.

The jawbone is at least 20 percent smaller than those from Liang Bua, suggesting H. floresiensis may have evolved from an even smaller hominin.

The work complicates the human story once again, much as the discovery of the controversial H. floresiensis — a.k.a. the hobbit — has upset earlier and simpler views of early human migrations around the globe.

(Meyer said they were working on reassessing old samples but would not specify which specimens they were studying — the mysterious «hobbit» H. floresiensis would be a worthy candidate.)

Not exact matches
