![]() ![]() floresiensis derived from an earlier Asian Homo erectus population and experienced substantial body and brain size dwarfism in an isolated insular setting. These results are however consistent with the alternative hypothesis that H. habilis or Australopithecus-like small-brained hominin species currently unknown in the Asian fossil record. floresiensis originated from a much older H. floresiensis, while at the same time does not support the hypothesis that H. ![]() This evidence contradicts the earlier claim of an entirely modern human-like dental morphology of H. erectus from the Early Pleistocene, whereas some of the molar morphologies are more progressive even compared to those of modern humans. The primitive aspects are comparable to H. ![]() floresiensis had primitive canine-premolar and advanced molar morphologies, a combination of dental traits unknown in any other hominin species. Based on extensive comparisons using linear metric analyses, crown contour analyses, and other trait-by-trait morphological comparisons, we report here that the dental remains from multiple individuals indicate that H. floresiensis’ unique physical characters have been intensively debated. The nature and evolutionary origins of H. Homo floresiensis is an extinct, diminutive hominin species discovered in the Late Pleistocene deposits of Liang Bua cave, Flores, eastern Indonesia.
