    Complex history of dog (Canis familiaris) origins and translocations in the Pacific revealed by ancient mitogenomes

    Archaeological evidence suggests that dogs were introduced to the islands of Oceania via Island Southeast Asia around 3,300 years ago, and reached the eastern islands of Polynesia by the fourteenth century AD....
