Final answer:
The variations in biological determinants between indigenous Australians and non-indigenous Australians can be attributed to a combination of genetic and cultural factors. Cultural factors include differences in lifestyle, such as hunter-gatherer practices versus agricultural practices. Genetic differences can affect characteristics like stature and skin pigmentation.
Step-by-step explanation:
The variations in biological determinants between indigenous Australians and non-indigenous Australians can be attributed to a combination of genetic and cultural factors.
One example of a cultural factor is the historical difference in lifestyle between the two groups. Indigenous Australians traditionally followed a hunter-gatherer lifestyle, while non-indigenous Australians have a history of agricultural practices and domestication of plants and animals.
Genetic differences can also play a role in variations between populations, affecting characteristics such as stature, facial features, and skin pigmentation. These differences may have developed over time due to geographical isolation and exposure to different environments.
