What is the last natural enemy of mankind, and the fear of it is engraved in our genes, and hundreds of thousands of people have died from it?

The last natural enemy of mankind is the cat, and the fear of it has gone deep into our genes. Even if cats are on the verge of extinction, people can't control the fear of cats in their genes. Even a kitten will make people feel that sensitive nerve.

Why cats are natural enemies of human beings? It is because we humans still have some advantages over other animals, but we have no advantages over cats. In terms of speed, not as good as cats, not as good as climbing trees, not as good as cats, and even not as good as cats in terms of reaction. Under such circumstances, cats are undoubtedly the natural enemies of human beings.

since we are natural enemies of human beings, we should start with our ancestors. At that time, when our ancestors lived in the same sky as the ancestors of cats, cats used apes as food. And from the ape-man whose head was punctured found in the cave, we can see how cruel cats are.

Then, human beings made progress slowly and invented many things. But even so, there is still no advantage against cats. What cats like best is to go out at night, and people don't know when and where it will suddenly come out. So although humans have defeated many natural enemies, there is still no way to do it in cats.

In ancient times, humans were also afraid of cats, such as tigers and leopards. Because these animals are huge, have sharp teeth and move quickly, it is easy to cause human injuries. From the idioms invented by people, we can see the fear of cats from the above.

Although most of these cats are extinct now, the fear of them has been deeply engraved in our genes.
