  Sheep, like turkeys and ostriches, are not considered the cleverest animals.British scientists said last Wednesday human may have underestimated(低估)the woolly creatures.They could be much smarter than we think.

  Researchers at the Babraham Institute in Cambridge, southern.England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.

  Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(區(qū)別)25 pairs of sheep faces and used electrodes(電極)to measure their brain activity, which showed they could remember 50 faces for up to two years.

  "If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.

  So hours of seemingly mindless eating grass may not be so mindless after all.

  Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much individuality and are frightened of just about everything.

  "All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.

  In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.

  "The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick."It is a very strange system.They are showing similar abilities in many ways to humans."

Sheep Smarter than Thought

London—Sheep, like turkeys and ostriches, are not considered the most clever animals. British scientists said last Wednesday humans may have underestimated the woolly creature. They could be much smarter than we think.

Researchers at the Babraham Institute in Cambridge, southern England, have shown that the animals have a good memory system and are extremely good at recognizing faces—which they think is a sure sign of intelligence.

Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish 25 pairs of sheep faces and used electrodes (電極) to measure their brain activity , which showed they could remember 50 faces for up to two years .

“If they can do that with faces, they have to have reasonable intelligence; otherwise, what is the point of having a system for remembering faces and not remembering anything else?” Kendrick said in an interview.

So hours of seemingly mindless eating grass may not be so mindless after all.

Kendrick believes sheep got their reputation as dumb (unable to speak, unintelligent) animals because they live in large groups and do not appear to have much individuality and are frightened of just about everything.

“All animals, including humans, once they are frightened, don’t tend to show signs of intelligent action,” he explained.

In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain which allows them to distinguish between many different faces which look extremely similar.

“The most important finding (of the study) is that they are able , both from a behavioral point of view and from looking at the way the brain is organized , to remember a large number of individuals for a very long time,” said Kendrick. “It is a very strange system. They are showing similar abilities in many ways to humans.”
