Primates of the Caribbean: Ancient DNA reveals history of mystery monkey
(PHYSorg.com Archaeology & Fossils)

Analysis of ancient DNA of a mysterious extinct monkey named Xenothrix-which displays bizarre body characteristics very different to any living monkey-has revealed that it was in fact most closely related to South America`s titi monkeys (Callicebinae). Having made their way overwater to Jamaica, probably on floating vegetation, their bones reveal they subsequently underwent remarkable evolutionary change.
