chosen.content: Aborigines are members of the Homo genus which, according to current scientific theories, had several species and subspecies which had varying degrees of physical differences between them. Aborigines belong to the species Homo sapiens, however they likely descended from a subspecies of Homo species which had physically larger brains and was thus more intelligent than other Homo species. As a result, some physical characteristics such as larger brains, larger skulls, and shorter facial features, such as a broad nose and more prominent cheekbones, are present in their evolutionary lineage and are visible in many Aborigines. This gives Aborigines an appearance somewhat similar to that of the Neanderthals, who are part of the same ancestry line.

rejected.content: Aborigines may have looked like Neanderthals because they share a common ancestor, the most recent being Homo sapiens about 400,000 to 500,000 years ago. As populations separated over time and evolved in isolation, the physical attributes of different populations became increasingly different. The physical characteristics of Aborigines resulted from adaptive processes in which they evolved to their specific environment, while the Neanderthal genetic traits slowly become dilute in the gene pools of people who no longer live in the specific environment they were designed for. Therefore, the physical characteristics of Aborigines, such as prominent cheekbones and broad, flat faces, resulted due to their ancestors having been adapted to the extremely dry environment of Australia for thousands of years.
