Tasmanian aborigines lost fish hooks and perhaps (I can't swear to this) even fire, after the place became an island some 15 K years back. I believe there was a genetic bottleneck due to low human pop numbers. Post-colonial theorists might argue that they *chose* to abandon these evil technologies and culturally adapted otherwise.
