Medicine’s Darin Croft discuss possibility of a ‘geographic bias’ in evolutionary theories of South American mammals

Evolution and possible ‘geographic bias’ Darin Croft, a professor of biology whose primary appointment is in anatomy at the School of Medicine, said his current research shows that certain prehistoric horse-like mammals in South America evolved differently than their Northern Hemisphere counterparts despite similar changes in climate and ecosystems. The discovery could reveal a previously unknown Northern Hemisphere bias in studying these and other ancient animals.
