Indigenous peoples of the Caribbean
The Classic Taíno lived in eastern Cuba, Hispaniola, and Puerto Rico. They spoke a dialect called Classic Taíno. Compared to their neighbors, the Classic Taíno had substantially developed agricultural societies. Puerto Rico was divided into twenty chiefdoms which were organized into one united kingdom or confederation, Borinquen. Hispaniola was divided into roughly 45 chiefdoms, which were organized into five kingdoms under the leadership of the chief of each area's premier chiefdom. Beginning around 1450, Classic Taíno from Hispaniola began migrating to eastern Cuba; they are conventionally known as the Cuban Taíno. The Cuban Taíno gained power over some of Cuba's earlier Western Taíno inhabitants, the Ciboney, but no regional or island-wide political structure had developed on the island at the time of Spanish colonization of the Americas.
Hispaniolan hutia
Five of the seven species in this genus are known only by skeletal remains, often found in association with human kitchen middens. These five species probably disappeared by the seventeenth century because of excessive hunting by people. "P. aedium" and "P. hylaeum" have been greatly reduced in range and numbers and are threatened by deforestation, hunting, and predation by the introduced small Asian mongoose ("Herpestes auropunctatus"). The human population of Hispaniola is increasing, most of the island's forest cover is being cleared for agriculture, and hutias are killed whenever encountered.
