Bees Can Recognize Human Faces

蜜蜂认识你？

Bees" bread and butter is flowers-there"s no reason they should be able to distinguish human faces. But they can. Back in 2005, Arian Dyer at Monash University showed that bees could identify people who they associated who with sugary snacks. But could they recognize humans, or did they just see them as weird flowers?

蜜蜂的食物来自花朵，它们怎么会识别人脸呢？但它们确实可以。早在2005年，莫纳什大学的阿瑞恩•戴尔就表示蜜蜂能通过把人和手中拿着的有甜味的零食联系起来以进行识别。但它们是否能识别人类，或仅仅把人类看做是奇怪的花朵？

Martin Giurfa at France"s Université de Toulouse contacted Dyer to work on that question. First, they drew simple images of facial features-dots for eyes, slashes for nose and mouth. The bees were trained to distinguish between an image with narrower features and one with wider ones.

法国图卢兹大学的马汀•居法与戴尔联系以期回答这个问题。他们首先拿了一些面部特征的简单图像--遍布小圆点的眼睛，打上了斜杠的鼻子嘴巴；蜜蜂们受到训练来识别这些面积大小不同的面部特征。

Then the scientists asked if the insects could distinguish facelike features from non-faces? The bees won sugary rewards when they picked out faces as opposed to pictures that just had random dots and dashes.

之后科学家们想知道它们能否将脸部特征与非脸部特征区别出来。蜜蜂们将脸部与只有随机圆点破折号的图片辨别出来后能得到甜味食物的奖励。

Finally, the critters faced their ultimate task: to pick out real faces from those that had the features scrambled. And: score. Bees could indeed differentiate faces from non-faces. The study was published in the Journal of Experimental Biology. Scientists hope that the simple bee brain could be a model for automated facial recognition. Which could help in FBI stings.

最后，这些小东西要面临终极任务了：把有真正人脸的图片和有干扰特征的区分开来。它们成功了，蜜蜂确实能辨别人脸和非人脸。该研究发表在《实验生物学报》上。科学家们希望简单的蜜蜂脑能作为自动面部识别的模型，这样就能在FBI搜查中帮上忙了。
