Australian Aborigines: geographical variability of craniological features.

Abstract

This work is devoted to the study of craniological traits of Australian aborigines (male and female samples) and their geographical differentiation applying a special program of cranial traits. According to the craniological classification (Pestryakov, Grigorieva, 2004), native population of Australia belongs to the Tropid craniotype, i.e. is characterized by a relatively small size and long, narrow and relatively high form of the skull. The primary settlement of the Australian continent could only origin in the North. There are two contrasting craniotypes in Australia, which probably reflect the two main waves of the aboriginal migration across the continent. The skulls of the first migratory wave were larger and relatively low-vaulted. They are mostly characteristic of the aborigines of South Australia, who later also migrated to the north, to the arid zone of Central Australia. The second major wave is characterized by smaller high-vaulted skulls, which are now characteristic of the population of the north of the continent (Queensland and, especially, the Northern Territory and North-West Australia). The territory of the southeast of Australia (Victoria and New South Wales states) is the most favorable area for human living. The two main migratory waves mixed there, which led to the observed craniological heterosis. The craniological samples of western and northwestern Australia are also of mixed origin, but are more comparable to the Northern Territory groups. The Tasmanians are significantly different from the General Australian population in terms of craniology. This is especially true for the female sample. Perhaps the ancestors of the Tasmanians represented the very first settlement wave of the ancient Sahul continent, before the separation of the island from the mainland.
