Different evolutionary theories of the pathway to modern Aboriginal Australians (Kow Swamp 1). Multiregional evolution is intermediate between extreme theories that each denies a long-term role for genic exchanges between regions. A purely Australasian pathway of in situ regional evolution has been supported by evidence of morphological continuity in this region, and complete replacement of non-modern populations by modern humans from Africa has been supported by evidence of large brains and loss of skeletal robusticity worldwide. According to the first theory, only Australasian specimens are considered ancestral to modern Australians, while the "Eve" theory recognizes only the Levantine specimen from Qafzeh, of the fossils depicted here, as ancestral to Australian Homo sapiens. However, according to the multiregional model, these observations of regional continuity and global change are not paradoxical and both are explained by intraspecific evolutionary processes. The multiregional theory, while recognizing genetic contributions from other areas, considers ancient, indigenous contributions important as well.
