“Ancient DNA” reveals that the scientific name for an extinct tortoise from Cape Verde refers to an extant South American species

Abstract We examined the type material of the extinct tortoise species Geochelone atlantica López-Jurado, Mateo and García-Márquez, 1998 from Sal Island, Cape Verde, using aDNA approaches and AMS radiocarbon dating. High-quality mitochondrial genomes obtained from the three type specimens support th...
