Horse Evolution Followed Twisty Trail, Study Says
Writing this week in the journal Science, paleontologist Bruce J. MacFadden said the evolution of horses involved many more twists and turns than previously imagined. Modern steeds did not follow a relatively smooth transition from the diminutive, foxlike forest browsers that were their earliest ancestors to those impressive, open-plains athletes we know today. Rather, horses fluctuated considerably in form and size over time.
