 In genetic terms, even many of those of pure Spanish origin may have North and West African ancestry brought from founder populations originating in the Canary Islands.Very few self-identified Black Puerto Ricans are of unmixed African ancestry, while a genetically unmixed Amerindian population in Puerto Rico is technically extinct despite a minuscule segment of self-identified Amerindian Puerto Ricans due to a predominant Amerindian component in their ancestral mixture.Research data shows that 60% of Puerto Ricans carry maternal lineages of Native American origin.
