Taíno
The Taíno were an indigenous people of the Caribbean. At the time of European contact in the late fifteenth century, they were the principal inhabitants of most of Cuba, Hispaniola (the Dominican Republic and Haiti), Jamaica, Puerto Rico, The Bahamas and the northern Lesser Antilles. The Taíno were the first New World peoples to be encountered by Christopher Columbus during his 1492 voyage. They spoke the Taíno language, an Arawakan language.
Hispaniola
In recent times, Dominican and Puerto Rican researchers identified in the current Dominican population the presence of genes belonging to the aborigines of the Canary Islands (commonly called Guanches). These types of genes also have been detected in Puerto Rico.
