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” pushed the “long-ears” (15[1])into their own burning trench, which is often identified with the Poike (15[1])ditch. Obsidian tools from this location called mata’a, (15[1])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 stopped the construction of stone platforms called ahu. Thor Heyerdahl’s book Aku-Aku argued that this island’s earlier South American inhabitants (10[1])had been displaced by Polynesians. For ten points, name this Chilean island known for its stone moai. ■END■
