Ancient DNA Reveals Genetic History of Caribbean World | Genetics, Paleoanthropology

In a new study of the genetic history of the pre-contact Caribbean, researchers analyzed genome-wide DNA data from 174 ancient individuals who lived in the Bahamas, Haiti and the Dominican Republic (collectively, Hispaniola), Puerto Rico, Curaçao and Venezuela, as well as the data from 89 previously sequenced ancient individuals.
