A MOLECULAR CLASSIFICATION OF THE EUTHERIA
The Atlantogenata is an ancient southern hemisphere radiation that includes the South American Xenarthra and the mainly African Afrotheria. Atlantogenata reflects the hypothesis that the opening of the Atlantic Ocean, which caused the break up of Gondwana, isolated one branch of this lineage in South America and another in Africa during the Cretaceous.
The Order Cetartiodactyla is based on molecular evidence that hippopotamuses are more closely related to whales than they are to other artiodactyls. Early cetacean fossils from Pakistan demonstrate that whales are artiodactyls. Thewissen, J. G. M., E.M. Williams, L.J. Roe, and S.T. Hussain. 2001.
