BAHAMAS: Researchers mapped the genome of an ancient Taino woman using DNA from one of her teeth. She was buried 1,000 years ago at a site called Preacher’s Cave on the island of Eleuthera. Her genome indicates that she is most closely related to present-day Arawakan speakers in northern South America, where her ancestors likely originated. But the study revealed that she is also partly related to some modern Puerto Ricans, underscoring the continuity there between the modern population and their precontact ancestors.
