Modern Mammals

A new study indicates that global warming, rather than mass extinction was behind a boom in reptile population and diversity. Researchers, from the Department of Organismic and Evolutionary Biology and the Museum of Comparative Zoology at Harvard University, have revealed that the evolution of reptiles began much earlier than previously thought.

Modern mammals, including humans, owe their keen sense of hearing to three tiny bones in the middle ear that were absent in their reptile ancestors, but the point at which this transformation occurred has remained unclear.
