This paper describes the cranial thickening of a late Pleistocene hominid (Willandra Lakes Hominid 50) from Australia. The unusual development of the vault structures in this individual has few, if any, equals among other hominids or more recent populations from around the world. The vault morphology is, therefore, described in terms of a pathologically related condition associated with the modern haemolytic blood dyscrasias, typical of sickle cell anamia and thalassemia. A possible palaeoepidemiology for these genetic adaptations among early Australasian populations is proposed together with a discussion of similar changes observed in the vault of the Singa calvarium from the Sudan. It is tentatively suggested that the cranial thickening of the Australian hominid has its origins in some form of genetic blood disease and that if this diagnosis is correct, this individual provides a rare glimpse of human biological adaptation in the late Upper Pleistocene.
