People Neeed To Keep Technology

Tasmania, an island in the southeastern corner of Australia, was connected to the mainland until it became isolated about 10,000 years ago when rising sea levels filled the Bass Strait, separating Tasmanians from mainland Australia. Fast forward to the 17th century, when Europeans first made contact with the Aboriginal Tasmanians, they discovered that the technology of the Tasmanians was significantly behind not only that of the mainland but also that their predecessors had possessed 10,000 years ago.

Losing the knowledge of technology once possessed, termed a technological regression, is a phenomenon that the inhabitants of Tasmania experienced. This involved reduced the complexity of their toolkits and a loss of certain skills and technologies that were present before isolation. Archaeological evidence suggests that, over millennia, Tasmanian Aboriginal people ceased to use some of the more complex technologies common among their ancestors and contemporaries on the mainland. For example, they stopped making bone tools, and the complexity of their fishing gear was reduced.

This simplification of technology has puzzled scientists and historians for years, leading to various theories about the reasons behind this technological regression. One prevailing theory suggests that Tasmania's small population size and isolation limited the transfer and maintenance of specialized knowledge. Complex technologies often require a critical mass of users and the transmission of knowledge across generations to sustain them. In a small, isolated population, the loss of certain skills can occur rapidly if not practiced and taught regularly, leading to a gradual simplification of technology.

The case of Tasmania's technological isolation provides valuable insights into the relationship between population dynamics and technological evolution. It highlights how isolation can affect the development and transmission of knowledge and skills, not only halting innovation but potentially causing regression when there are not enough people to sustain the current level of knowledge over time.
