Carl Lipo and Terry Hunt proposed that this location’s population of Jubaea palms was devastated by Rattus exulans, leading to the practice of lithic mulching. A war in this location ended when the “short-ears” (-5[1])pushed the “long-ears” into their own burning trench, (15[2])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[1])argued that environmental degradation in this location (10[1])stopped the construction of stone platforms called ahu. Thor (-5[1])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.
