Then that foot stops and the other one accelerates.
然后那只脚停止,另一只开始加速。
And so on. Thinner, lighter things are easier to accelerate than heavy, massive ones.
之后往复。相比沉重,巨大的脚掌，更薄、更轻则更容易加速。
So if you want speed, put the muscles up high and the skinny down low.
所以,如果你想要加速,腿部上部分的肌肉要发达而底部则要瘦小。
Speed if you really want speed, you could go even further and pare down the foot,to decrease lower leg mass even more.
如果你真正想要速度那就加速,你可以走得更远,减少脚部压力,减少小腿的质量。
A few million years of evolution and you'll wind up with…you guessed it.
经历过几百万年的进化,你就会…你猜对了。
A hoof.
这就是马蹄。
