Summary:
A Johns Hopkins paleobiologist has uncovered clues that the horses (and camels and rhinos) that roamed North America millions of years ago went extinct because of climate change that radically changed their food supply. This new understanding of the extinctions is relevant to today's discussions of global warming.

Johns Hopkins paleobiologist Steven Stanley has sleuthed out clues to the evolution of horses, coming up with a new solution for an enduring mystery: What caused the extinction of many equine species and other mammals 6 million years ago?
