Complete Columbian mammoth mitogenome suggests interbreeding with woolly mammoths
Abstract Background Late Pleistocene North America hosted at least two divergent and ecologically distinct species of mammoth: the periglacial woolly mammoth (Mammuthus primigenius) and the subglacial Columbian mammoth (Mammuthus columbi). To date, mammoth genetic research has been entirely restrict...
