Which animals are smart? Your answer may be dogs, monkeys or elephants. Now we can put one more animal into the list: sheep.
Scientists from Cambridge University said that they can teach sheep to tell familiar (熟悉的)human faces from other unfamiliar ones.
Before testing, scientists let the sheep take a look at pictures of four famous people, such as Barack Obama and British actress Emma Watson. Then the sheep went into a room with two computer screens. Each screen showed a human face. One screen showed a famous person and the other screen showed a common person。The sheep would always walk to the screen with the face of famous persons.
Then, the scientists wanted to know the sheep's ability to recognize(认出) them from a photo. They put their own photos on screens along with some pictures of unfamiliar(不熟悉的) faces. Not surprisingly, the sheep could tell the scientists from others.
After noticing the animals' ability to recognize people, scientists gave them a new job. They wanted to see the farm animals' ability to recognize the same person if the picture only showed half of the person's face or just one side of a person. The animals were still able to recognize them, though they were a little slower to recognize the pictures than before.
The results show that the animals' face-recognition( 面部识别) abilities are similar to those of monkeys and humans. Face recognition is a difficult job. But sheep have big brains(大脑). When they see other sheep, they can also recognize one another.
The scientists said it might be interesting in the future 10 find out whether sheep can recognize different human facial expressions(表情)
