人类为什么能成为地球上最厉害的长跑健将？

So, why did humans get to be such great endurance runners, anyway?

那么，人类为何能成为如此卓越的长跑健将呢？

Some anthropologists believe this became important around 2-3 million years ago, when we started hunting and scavenging. Because we couldn't chase down a gazelle like a cheetah, early humans learned persistence hunting. Where they would track prey over long distances until the prey either overheated or was driven into a trap.

一些人类学家认为，大约在两三百万年前，当人类开始狩猎和觅食时，长跑能力变得至关重要。因为人类无法像猎豹一样追捕瞪羚羊，于是我们学会了耐力狩猎。他们会追踪猎物很长一段距离，直到它们体温过热或被逼进陷阱。

In fact, persistence hunting remained in use until 2017, such as with the San people of the Kalahari Desert.

事实上，到了21世纪，依然有人类在使用这种狩猎方法，例如，喀拉哈里沙漠的非洲原住民桑人。

But distance running can still help you, even if you're not interested in running down your next meal.

即便你现在对追猎觅食没兴趣，但长跑依然有益身体。

Studies show running can lower body weight, body fat, and cholesterol levels. And the longer you train, the greater the health benefits. Just one year of training has been shown to reduce body weight by about 7 lbs, lower body fat by 2.7% and decrease resting heart rate by 2.7%.
