Fastest Four Legs in America~

Everyone knows the fastest land animal in the world is the cheetah, but not everyone knows the second fastest animal in the world is the North American Pronghorn Antelope. Pronghorns can run up to 55 mph for .5 miles. They can run 35 mph for up to 4 miles. In fact, they can run at high speeds for more sustained periods than African Cheetahs.

This is a puzzling ability because no predator in North America can run fast enough to catch a pronghorn, so why is it necessary for pronghorns to run this fast?

Biologists believe that pronghorns evolved to run these speeds in order to evade the now extinct American Cheetah.

During the Pleistocene era, there were twelve species of pronghorns in North America. By the time humans settled on the continent there were five.

We are now left with one remaining species. Pronghorns are in fact not antelopes at all but a unique species named Antilocapra Americana. Handsome creatures aren’t they?
