Chapter 710: Is it the same as us?

Liu Xueqing listened to the example explained by the two. Although the bat has not been mentioned yet, she understands one thing. The culling and repelling of the bat may eventually end in failure, and if the action is really strong, it may bring some trouble. positive effect.

I wonder what role bats have on the ecosystem?

Fang Ye did not directly address this issue.

Before the staff went to chase bats away, he also followed several times and asked the citizens why they were afraid of bats.

One very important reason is the poor image of bats!

It is somewhat similar to a mouse, and has a hideous appearance, sharp teeth, and can fly.

Subconsciously associate them with filth and disease.

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

The fluffy and chubby giant pandas and red pandas don't think they are dangerous, they only think that they are cute and cute, while snakes, bats, spiders and other animals that do not conform to the public's aesthetics find them very scary, even if they are not dangerous.

So Fang Ye planned to start with the explanation from the aspect of appearance, so that the audience could understand, so as to eliminate fear.

"Bats are also an animal with many misunderstandings. In fact, it's no wonder everyone is afraid of bats. After all, they are ugly and don't have human rights."

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

Wang Yan said: "I have never been afraid of bats. When I was young, I felt that they were very mysterious. They only came out at dusk, and when there was still a little afterglow in the evening, a group of flocks appeared from nowhere and flew around in the sky. .

Like a fairy tale, Cinderella was enchanted, put on crystal shoes, everyone danced together, and then when the day broke, they all magically disappeared again. "

The host said: "I also have a deep impression of bats. When I was a child, I watched "The Legend of the Dragon Slaying the Heaven" for a while. The blue-winged bat king Wei smiled and took people away and sucked blood. It gave people a creepy feeling and caused some fear of bats. .

As soon as it gets dark, they come out in large swaths, flying fast and low, and they don't dare to go out for fear that they **** blood, but my mother told me that there is no need to worry, they will not bite. It seems that I rarely see bats when I grow up. "

Fang Yedao: "Everyone has different sources of fear about bats. There may be many people who have been affected by TV dramas, various novels, and film and television works. Vampires have sharp fangs and a gloomy appearance, taking advantage of the dark night. Going out to **** human blood.

Looking ugly is indeed a main reason. In the process of communicating with the citizens, one of the questions we are often asked is why this bat looks so ugly and looks very disgusting.

His face was wrinkled, layer upon layer, and he couldn't understand what it was and couldn't accept it.

In fact, the bat's face grows like this. This is like we humans have flexible fingers, giant pandas have black and white fur, and red-crowned cranes have long pointed and long mouths. They all evolved to better adapt to the external environment. It's a normal thing.

Everyone imagine, if we stand in front of a bottomless, dark, empty cave, we don't know how deep the cave is, what would we do? "

The host thought about it for a while and said: "Pick a stone and throw it down. How long will it take to hear 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. .Is it dangerous to fall, is it very straight or has various twists and turns?

This is actually the same as the ability of a bat. "

The host said: "Listen to the voice to distinguish the position."

Wang Yan smiled and said: "Like those blind heroes, they can still fight back and forth with the enemy by listening to the wind."

Fang Yedao: "When we humans cannot judge the position by vision, it is our instinct to use sound to locate it is still inscribed in our genes.

For another example, when we talk face-to-face, this is the normal voice. If we see a friend across the road while shopping, we will instinctively raise our voice and let our voice face him and call his name. If the car comes The car is very noisy, and you may even put your hands on your mouth to make a horn-like, shouting loudly.

To call people in this way, we change the audio frequency from low frequency to high frequency, increase the penetration ability, the directivity and directionality will be stronger, and the transmission distance will be longer.

When a bat sees a mosquito or fly in the air, it will also raise its own audio frequency so that it can locate and prey more accurately. So from this perspective, humans and bats have the same ability. "

Humans and bats have the same ability?

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

Listening to Fang's explanation of the wild activities, it feels that the mist covering the bats is gradually dissipating, and it is no longer so mysterious!

With such a wonderful connection, the fear of them disappeared unknowingly.

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

Just when I was flying in the air, if I caught this fly and opened my mouth to chew, there would be no way to continue shouting sound waves in my throat.

Then think about it, everyone, is this a very dangerous thing? If you hit a wall or hit a tree and fall into the water, you didn't die because you were hunted. If you hit the wall and hit one end to death, it would be too useless. .

So the bat came up with a very good method, which is to use the nose.

Although bats still use their vocal cords to emit sound waves, they use their noses, and their noses form a complex structure, which can be better directional transmission, and the ears are correspondingly enlarged, so that they can distinguish. Be aware of these sounds, and be able to distinguish the sound waves from yourself when many of the same species exist at the same time. "

Liu Xueqing, who was watching TV, suddenly said, "Oh~ It turns out that bats grow like this for this reason, and their noses are wrinkled together!"

Yingying's dad also sighed: "So you can't just look at the appearance!"

It's like seeing a person on the street with a large mottled and ugly face, and you will subconsciously feel terrified.

But when I understand that this person was actually burned to rescue a trapped child in the fire, he will no longer be afraid, but will have a feeling of respect and admiration.

The viewers who watched TV had a new understanding of bats at this time.

I feel that bats are not so ugly anymore, the sense of fear has been eliminated a lot, and I even marveled at the magic of species evolution!

It is indeed an interesting ability to emit ultrasound through the nose.
