Brief communication: “Pathological” deformation in the skull of LB1, the type specimen of Homo floresiensis

If the holotype of Homo floresiensis , LB1, suffered from a severe developmental pathology, this could undermine its status as the holotype of a new species. One of the proposed pathological indicators that still remains untested is asymmetric distortion in the skull of LB1 (Jacob et al.: Proc Natl Acad Sci USA 103 (2006) 13421–13426). Here, we present evidence that LB1 exhibits antemortem craniofacial deformities that are consistent with posterior deformational (positional) plagiocephaly. This is a relatively common condition in modern people with no serious associated health problems and does not represent a severe developmental abnormality in LB1.
