Naturalist: The recent claims that the Tasmanian tiger is not extinct are false. The Tasmanian tiger' s natural habitat was taken over by sheep farming decades ago, resulting in the animal' s systematic elimination from the area. Since then naturalists working in the region have discovered no hard evidence of its survival, such as carcasses or tracks. In spite of alleged sightings of the animal, the Tasmanian tiger no longer exists.
Every naturalist working in the Tasmanian tiger's natural habitat has looked systematically for evidence of the tiger's survival is an assumption on which the naturalist's argument depends.
