Carl Lipo and Terry Hunt proposed that this location’s population of Jubaea palms was devastated by Rattus exulans, (15[1])leading to the practice of lithic mulching. A war in this location ended when the “short-ears” pushed the “long-ears” into their own burning trench, which is often identified with the Poike ditch. Obsidian tools from this location called mata’a, used as evidence of widespread warfare, may not have been sharp enough for weapons. (*) Jared Diamond’s Collapse (10[2])argued that environmental degradation in this location (10[1])stopped the construction of stone platforms called ahu. Thor Heyerdahl’s book Aku-Aku argued that this island’s earlier South American inhabitants had been displaced by Polynesians. For ten points, name this Chilean island known for its stone moai. ■END■
