History

The fastest animal in the Western Hemisphere

Many people know that the cheetah is the fastest. Develops up to 100 km per hour! But the cheetah runs as little more than 200 meters, and then half an hour, and it is hard to die. A pronghorn at a rate of almost 90 km per hour runs several kilometers, and a rate of 65 km / h - 15 km! Why nature has created in the process of evolution until such a surprise? But half of this performance enough to leave behind, predators that may threaten him on the prairie and the desert: pumas, wolves, coyotes ...

This efficiency, there may be residue from the 18 000 years ago, when he lived on the prairies of the American species of cheetah. We do not know how the cheetah ran around, but probably it is to escape before it was created this unusual mechanism - pronghorn.

Speed and endurance to run depends on how quickly the body can deliver oxygen to working muscles. The efficiency of the lung is five times greater than for example in a large goat, the quantity of blood thrown at one heartbeat - three times greater.
