Chapter 713

Liu Xueqing listened to the example explained by the two people. Although he hasn't talked about bats yet, he understood one thing. Killing and driving bats may end in failure, and if he has great action power, it may bring some bad effects.

Curious, what role do bats play in ecosystems?

Fang ye did not directly talk about this issue.

Before, the staff went to drive away bats, and he also followed them several times to ask why citizens were afraid of bats.

A very important reason is the poor image of bats!

It is somewhat similar to a mouse, and it has a ferocious face, sharp teeth and can fly.

Subconsciously associate them with dirt and disease.

It is also human nature to use appearance to evaluate the danger degree of animals.

Hairy and chubby giant pandas and red pandas don't think they are dangerous. They just think they are cute and cute. Animals that don't conform to the public's aesthetics, such as snakes, bats and spiders, feel very scary, even if they are not dangerous.

Therefore, Fang Ye plans to explain from the aspect of appearance first, so that the audience can understand it, so as to eliminate fear.

"Bats are also a kind of animal with many misunderstandings. In fact, it's not surprising that people are afraid of bats. After all, they are ugly and have no human rights."

Fang ye made a joke, and the host and Wang Yan laughed.

Wang Yan said, "I've never been afraid of bats. When I was a child, I felt that they were very mysterious. They came out every evening. When there was still a little afterglow in the evening, groups of bats came out and flew around in the sky.

Like a fairy tale, Cinderella was enchanted, put on crystal shoes, everyone danced together, and then as soon as dawn, they all magically disappeared. "

The host said: "I also have a deep impression of bats. When I was a child, I watched the story of relying on the sky to kill the dragon for a while. Wei Yixiao, the green winged bat king, kidnapped people and sucked blood, which gave people a creepy feeling and led to some fear of bats.

As soon as it was dark, a large number of them came out. They flew fast and low. They didn't dare to go out for fear that they would suck blood. However, my mother told me not to worry, they wouldn't bite. It seems that they can rarely see bats when they grow up. "

Fang ye said: "everyone's fear of bats comes from different sources. Many people may be affected by TV dramas, various novels and film and television works. Vampires have sharp fangs and gloomy faces. They go out to suck human blood while taking advantage of the dark wind at night.

Ugly is indeed the main reason. In the process of communicating with the public, we are often asked why bats are so ugly and look disgusting.

His face was wrinkled, layer by layer. He couldn't understand what it was and couldn't accept it.

In fact, the face of bats looks like this. It's like we humans have flexible fingers, giant pandas have black and white fur, and red crowned cranes have sharp and long mouths. They all evolved to better adapt to the external environment. It's very normal.

Let's imagine, if we stand in front of a dark and empty cave with no bottom, we don't know how deep the cave is, what will we do? "

The host thought for a moment and said, "pick up a stone and throw it down. How long can the stone echo?"

Fang ye said, "yes, we will throw a stone, or stand on the edge and shout down. Through the echo from the darkness, we can know the depth of the cave, and even judge whether the cave is empty or narrow. Will it be dangerous to fall down, is it very straight or has all kinds of twists and turns?

This is actually no different from the ability of bats. "

The host said, "listen to the voice and identify the position."

Wang Yan said with a smile, "just like those blind heroes, they can still fight back and forth with the enemy by listening to the palm wind."

Fang ye said: "when we humans can't judge the position through vision, it's our instinct to use sound positioning to be still engraved in our genes.

For another example, when we talk face to face, it is such a normal voice. If we see a friend across the road when shopping, we will instinctively raise our voice and let our voice shout his name towards him. If the car is noisy, we may put our hands on our mouths, make a horn and shout loudly.

In this way, we change the audio frequency from low frequency to high frequency, which increases the penetration ability, the directivity and directivity will be stronger, and the propagation distance will be farther.

When a bat sees a mosquito or fly in the air, it will also improve its audio, so that it can locate and prey more accurately. Therefore, from this point of view, both humans and bats have the same ability. "

Do humans and bats have the same abilities?

Many viewers who watched the program were stunned when they heard this sentence!

Listen to Fang wild animal's explanation for example. I feel that the fog shrouded in bats gradually dissipates and is not so mysterious!

With such a wonderful connection, the fear of them dissipated unconsciously.

Fang Ye continued: "bats need to solve a problem in the process of evolution.

When flying in the air, if I catch the fly and open my mouth, I can't continue to shout out sound waves with my voice.

Let's think about it. Is this a very dangerous thing? If you hit a wall or a tree and fall into the water, you don't die from being hunted. If you hit one end of the wall, you'll die too cowardly.

So the bat came up with a good way to use his nose.

Although bats still use their vocal cords to send out sound waves, they use their noses, and their noses form a complex structure, which can better directional propagation, and their ears are correspondingly larger, so that they can distinguish these sounds clearly, and can distinguish the sound waves they send out when many of their kind exist at the same time. "

Watching TV, Liu Xueqing suddenly said, "Oh, that's why bats grow like this. Their noses are wrinkled together!"

Yingying's father also sighed, "so you can't just look at your appearance!"

It's like seeing a person on the street with a large mottled and ugly face, subconsciously feeling afraid.

But when we learn that this person is actually burned to save a trapped child in a fire, we will no longer be afraid, but will have a feeling of respect and admiration.

TV viewers have a new understanding of bats at this time.

It seems that bats are not so ugly, their fear has been eliminated, and they are even amazed at the magic of species evolution!

Sending ultrasound through the nose is really an interesting ability.
