13,000 years ago, the ice age cheetah was the pronghorn's greatest enemy.
在13,000年前的冰河时代，猎豹是叉角羚的天敌。
And pronghorn would have needed all their amazing speed.
叉角羚以其令人惊叹的速度著称。
The American cheetah was larger than its African cousin. But it had the same Achilles' heel.
美洲豹比非洲豹的体型要大。但他们的致命弱点相同。
A cheetah's high-performance muscles overheat in minutes, and unlike pronghorn, they can't switch to cruising speed.
猎豹高性能的肌肉会在几分钟内变热，和叉角羚不同的是，猎豹不能长时间保持这一速度。
So if the pronghorn managed to outrun the cheetah for the crucial first few hundred meters, it would probably survive.
所以如果叉角羚能在开始关键的几百米内跑过猎豹，那便有可能幸存。
The cheetah hasn't roamed the plains of North America for thousands of years, but pronghorn are still prime for the chase.
几千年来，猎豹一直没有在北美平原游荡，而叉角羚在这场角逐中依然占据优势。
Other extinct links to Africa had been found in caves steep in the Ozark Mountains of Missouri.

Preserved in mud were huge prints recreated here, more than 18 centimetres wide. What could have made them?
这里的淤泥中保存下来一些脚印，有18多厘米宽。这是什么动物的脚印？
They belonged to another ice age cat, the top cat of the plains, a lion.
他们是另一种冰河时代的猫科动物，也是美洲平原猫科动物的王者——狮子。
