The blurring of such boundaries accords with strong cultural emphases on diffusion and the expansion of networks of relationships through kinship, marriage alliance, exchange, and religious activities.
Greater emphasis on maintaining boundaries, together with higher levels of ethnocentrism and intergroup conflict, were more likely (but not invariably) to be found in resource-rich areas with higher population densities.
However, most now accept that there was a wide range of variation in pre-European populations.
Estimates of Aboriginal population vary from 300,000 to more than 1,000,000.The dingo, a type of wild dog, appeared in Australia only 5,000 to 3,000 years ago, which postdates the time that Aboriginal people began hafting small stone implements into composite tools some 8,000 years ago.Whereas the dingo was introduced from Southeast Asia, the small implements appear to be independent inventions from within Australia.It has long been conventionally held that Australia is the only continent where the entire Indigenous population maintained a single kind of adaptation—hunting and gathering—into modern times.Some scholars now argue, however, that there is evidence of the early practice of both agriculture and aquaculture by Aboriginal peoples.
