In the impression of most people, sheep is a kind of ingenuity, softness, weakness, and harmless creatures. They like to eat grass, wander on the mountains, and be frightened by all kinds of small things. However, is this all the sheep? In fact, sheep are not the same as people think.

Sheep not only has amazing IQ, but also has its memory and cognitive ability than many animals. You can produce friendship, and sheep even sad when their friends were sent to the slaughterhouse. At the same time, sheep are still very destructive.

A study released by the famous scientist Kis in 2001 said that sheep can remember and identify at least 50 different faces, and these memories can be preserved in their brains for two years, which is longer than many human memories. At the same time, Kis and his colleagues also found that sheep can distinguish between human facial expressions. In comparison, they prefer to smile and frown expressions. Australian scientist Caroline also studied the IQ's IQ, and she found that sheep could learn to come out of a complex maze.

In 1990, scientists at the University of California conducted three years of observation of male sheep. Observation found that there was deep friendship between sheep, and they would help each other when they needed. When weaker companions are bullied, strong sheep will prevent this incident from continuing. A report published by the International Animal Foundation in 2009 shows that sheep can experience a series of feelings like people, including fear, anger, boring and happiness, and so on.

People understand that sheep are not as stupid as people think. Although the creatures such as sheep have long been rooted in human culture, most people know very little about this interesting creature. As early as 10,000 BC, sheep have been domesticated by humans, which allows humans to use their meat, hair and milk.

Even today, 10,000 years and two thousand years later, sheep still preserve some of their ancestors' survival skills. For example, if you are too close to the sheep, they will kick you fiercely. The ability of sheep on the cliffs is far beyond humans. In addition, their narrow pupils also give them excellent vision. It is worth noting that sheep is also a very destructive animal. When a large amount of sheep eats, the straw stems on the ground will be cleaned, which is fatal for wild herbivores. It can be said that the large -scale raising sheep is one of the causes of climate change.
