　It’s become pretty clear that contagious yawning is linked to empathy. But why?Perhaps the best explanation for why we yawn, as well as why yawning is contagious, can be found around the watering hole on the savannah tens of thousands of years ago.
　　Some scientists believe that yawning is an involuntary response to a stressful situation: When we yawn, we increase the blood flow to the brain, thus making us more alert. Contagious yawning may be a method of quiet communication by which our ancestors spread the word that a hungry lion was nearby. Fear is an emotion with which we can empathize, and yawning may serve as a cue by which we spread that fear.

很显然,传染性打哈欠和移情作用有所关联.但是为什么呢?也许关于为什么我们会打哈欠同时传染给别人的最好解释能够在几千年前大草原上的几十个水坑找到答案.
一些科学家认为打哈欠是一种不受意志控制的对紧张局势的一种反应：当我们打哈欠的时候,我们流向大脑的血液量就会上升,因此让我们更加提高警惕.传染性打哈欠也许是我们的先祖在面对一只饥饿的狮子时,发出的对外界的一种无声的交流.害怕是一种使我们产生共鸣的情感,而打哈欠也许是作为一种使我们分散害怕担忧的暗号.
