The indigenous people of Tasmania are clearly related to the indigenous people of Australia, but were separated from them when the land bridge between Australia and Tasmania disappeared approximately 10,000 years ago. Two thousand years after the disappearance of the land bridge, however, there were major differences between the culture and technology of the indigenous Tasmanians and those of the indigenous Australians. The indigenous Tasmanians, unlike their Australian relatives, had no domesticated dogs, fishing nets, polished stone tools, or hunting implements like the boomerang and the spear-thrower.

"Surprising" Phenomenon

Why did indigenous Australians and indigenous Tasmanians develop such different cultures and technologies within 2,000 years of being separated?

Objective

The correct answer must fail to explain why indigenous Australians developed technologies that indigenous Tasmanians did not. Every wrong answer, meanwhile, will offer a difference between the groups explaining why their cultures and technologies diverged.

After the disappearance of the land bridge the indigenous Tasmanians simply abandoned certain practices and technologies that they had originally shared with their Australian relatives.

This is a difference between the groups that explains the technological discrepancy. Both cultures were positioned to make the developments in question, but the indigenous Tasmanians gave up some tools and practices.

Devices such as the spear-thrower and the boomerang were developed by the indigenous Tasmanians more than 10,000 years ago.

This deepens the mystery. Indigenous Tasmanians invented these technologies, yet they were absent from Tasmanian society 2,000 years later.

Technological innovations such as fishing nets, polished stone tools, and so on, were imported to Australia by Polynesian explorers more recently than 10,000 years ago.

This explains the technological discrepancy. Polynesian explorers are responsible, because they introduced technologies to indigenous Australians but not to indigenous Tasmanians.

Indigenous people of Australia developed hunting implements like the boomerang and the spear-thrower after the disappearance of the land bridge.

This contributes to an explanation of the technological discrepancy. Indigenous Australians developed these tools after the land bridge disappeared, so they were not introduced to indigenous Tasmanians.

Although the technological and cultural innovations were developed in Australia more than 10,000 years ago, they were developed by groups in northern Australia with whom the indigenous Tasmanians had no contact prior to the disappearance of the land bridge.

This contributes to an explanation of the technological discrepancy. Indigenous Tasmanians were not introduced to the developers of these technologies before the land bridge disappeared.
