Liu Wei's behavior of combing its hair can bring a sense of intimacy to the zebra. It blinked twice and its eyebrows became much gentler.

"That's right! I have no idea about your wife. We are not the same species. I just want to be close to you and have a companion on the way forward!" Liu Wei patiently combed his mane, not because the zebra had just Emotions arise from the performance that almost killed him.

The other female zebras also came close, clinging to each other and communicating in a special way.

Liu Wei smiled and said: "Brothers, the female horses will definitely praise me in front of the male horses. The look in their eyes is full of love! It seems that I have become their very important human friend!"

After saying that, he walked up with the brush again.

The male zebra leader took the initiative to step aside and let Liu Wei and his harem beauties play.

It seems that it has admitted its defeat.

In the zebra's mind, only the winner can lead the group, and the loser will take the initiative to hand over his power.

The criteria for victory and defeat are actually determined by the zebra's psychological activities.

Liu Wei waved to it, but it ignored him.

"Okay! I will temporarily replace you as the leader for a few days!"

Liu Wei stroked the female zebra's back, "I will accompany you until you join the migrating army. I hope we can have a pleasant time!"

After making the declaration of competency, Liu Wei turned back to face the live broadcast camera, "Compared to other herbivores in Africa, zebras have enviable digestive abilities and can survive healthily even in harsh desert areas. This This is also the reason why plains zebras are widely distributed on the African continent and have particularly strong survivability.

At the same time, its anti-viral ability is also very strong. We all know that Africa is an area where diseases occur frequently, not only in humans, but also in animals. According to statistics, zebras have the highest disease resistance on the grasslands. One of the best! "

"Awei, tell me about the stripes on a zebra!"

"Yes! Why do zebras have so many stripes?"

"Does it have any special function?"

Many people, like the viewers in the live broadcast room, first know the zebra because of the lines on its body, and are also very curious about its lines!

Liu Wei said: "The stripes and interval widths on zebras are formed in the early stages of pregnancy of female zebras.

A fixed, equally spaced stripe is actually formed in the embryo.

Later, in the process of embryonic development, due to the different development conditions of various parts of the body, after the cub is born, the stripes formed by each part will also be obviously different, some are wider and some are narrow.

For example, the stripes on the zebra's neck are relatively wide. The shape of the stripes on the neck is first formed in the seventh week of embryonic development, and is determined before the neck elongates.

The stripes near the nostrils are very thin. Generally, the stripes in this area are formed in the fifth week of embryonic development, that is, before the nose enlarges.

Zebras have the widest stripes on their rump, which develop in proportion to the rest of their body.

At the same time, stripes cannot appear earlier than the fifth week of embryonic development, because zebras have a striped tail, and this tail has not yet appeared before the fifth week of embryonic development, when the length of the embryo is approximately 32 mm, the number of stripes is about 80. From this, it can be deduced that the width of each stripe initially determined is about 400 microns, that is, each stripe has the width of 20 embryonic cells.

Finally, there are the stripes on its limbs, which extend in a horizontal direction. Research shows that it is most likely formed because all the stripes on the legs mechanically turn at an angle during embryonic development. "

"It feels so complicated!"

"I don't understand!"

"It's very simple. What Ah Wei means is that the stripes on zebras are already formed before they are born!"

"Nonsense! I want you to tell me!"

"Hahaha! In fact, it is somewhat similar to the development process of human embryos. If you are interested, you can study it!"

Liu Wei smiled and said: "I don't know much about genetic knowledge. My teacher is very knowledgeable in this area. If I have the opportunity, I will ask him to introduce it to you in detail."

"Let's talk about the role of stripes again. The research on zebra stripes is very different in various time periods. This also reflects the limitations of scientific research. After all, the times are progressing, and the level and direction of human cognition will change. Big change.

In the early days of research, scientists believed that the stripes on zebras were the main mark for identifying each other among similar species. They were also the protective colors formed by zebras to adapt to the environment, which could play a very important defensive role.

The African savanna is a paradise for large predators. Although zebras have strong running abilities, their defense methods are still very immature in the face of cats and crocodiles with superb hunting skills. They often make no noise. Approaching the zebra and launching a surprise attack will not give the zebra much chance to react.

If a zebra has a chance to escape from an attack, the markings on its body will help.

In the open grasslands and desert areas, this kind of black-brown and white stripes reflect different light under the sunlight or moonlight, which plays the role of blurring or distracting the outline of its body. Looking at it, it is difficult to distinguish it. distinguish the surrounding environment.

When a zebra escapes, it is easy to distract the predator, making it difficult for the predator to identify the target of pursuit. The predator may give up hunting due to hesitation.

This kind of research and understanding has also inspired mankind to apply the principle of stripe protective color to maritime operations. During World War II, the United States painted colors similar to zebra stripes on warships to blur the sight of the Japanese army and confuse the Japanese army. .

However, in recent studies, zoologists have found that the stripes on zebras can distract and weaken the attention of mosquitoes and flies on the grassland, effectively preventing mosquito bites. To prove this conjecture, American scientists conducted an experiment , painted zebra-like stripes on the elephant's body, and the experimental results were very ideal. "

"Damn it, this is okay!"

"No need to light mosquito coils anymore, just paint on your body!"

"You are awesome! Remember to post pictures when the time comes!"

Liu Wei looked at the barrage and smiled: "I didn't ask you to paint!"

The audience laughed wildly.

The atmosphere in the live broadcast room is very harmonious.

After Liu Wei combed the zebra's hair one by one, he sat on the ground and rested for a while.

Before the sun goes down, the zebra herd will continue to move forward, not very fast, and Liu Wei does not ride on it, but follows behind with Brother Flathead and Pangpang.

It's getting dark.

A herd of zebras walks into the jungle, looking for a safe place to rest.

The sleeping posture of zebras is different from that of other animals of the genus Equus. Horses raised by humans sleep standing up, while zebras sleep lying down, flat on the ground.

During the break, there will still be members of the group who are responsible for keeping watch on the outside, and they take turns on duty.
