Liu Wei's behavior of grooming it can bring a sense of affection to the zebra, it blinked twice, and its eyebrows were much more docile.

"That's right! I don't have any thoughts about your daughter-in-law, 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 feeling emotional because of the zebra's performance that almost killed him just now.

The rest of the female zebras also leaned in, snuggling up to each other and communicating in a special way.

Liu Wei smiled and said: "Brothers, the female horse must praise me in front of the male horse, you look at their eyes, 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, allowing Liu Wei to play with his harem beauties.

It seems that it has admitted the fact that it has lost.

In Zebra's thinking, only the winner can lead the group, and as the loser will voluntarily hand over the power.

The criteria for victory and defeat are actually determined by the zebra's mental activity.

Liu Wei beckoned to it, but it ignored it.

"Okay, I'll take your place as the leader for a few days!"

Liu Wei stroked the back of the female zebra, "I will accompany you until you integrate into the migratory army, I hope we can have a good time!"

After speaking the declaration of competency, Liu Wei turned back to face the live camera, "Compared with other herbivores in Africa, zebras have enviable digestive ability, even in desert areas with harsh conditions, they can be healthy, which is also the reason why plain zebras are widely distributed on the African continent, and their survival ability is particularly strong."

At the same time, its anti-virus ability is also very strong, we all know that Africa is a frequent disease area, not only in humans, but also in animals from time to time, according to statistics, zebra's disease resistance is one of the best in the grassland!"

"Ah Wei, tell me about the stripes on the zebra!"

"yes, why are there so many stripes on zebras?"

"Is there any special effect?"

Many people, like the audience in the live broadcast room, know the zebra first because of the lines on its body, and at the same time they are very curious about its lines!

"The formation of stripes and interval widths on the zebra is in the early stages of pregnancy in the female zebra, and a fixed, equally spaced stripe is actually formed in the embryo.

Later, in the process of embryonic development, because of the different development of various parts of the body, after the birth of the pup, the stripes formed by each part are also obviously different, some are wide and some are narrow.

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

The strips near the nostrils are very thin, and the streaks in this area are usually formed in the fifth week of embryonic development, that is, before the nose expands.

The stripes on the zebra's rump are the widest, and the hips develop in proportion to the rest of the body.

At the same time, the streaks should not appear earlier than the fifth week of embryonic development, because the zebra has a striped tail that has not appeared before the fifth week of embryonic development, at which time the length of the embryo is about 32 mm, and the number of stripes is about 80, from which it can be deduced that the width of each stripe is about 400 microns, i.e. the width of each stripe is 20 embryonic cells.

Finally, there are the stripes on its limbs, which extend horizontally, and studies have shown that it is likely that all the stripes on the legs are mechanically turned at an angle during embryonic development. ”

"It feels so complicated!"

"I don't understand!"

"Quite simply, what Ah Wei means is that the stripes on the zebra's body are formed before they are born!"

"Nonsense!

"Hahaha! Actually, it is a bit similar to the development process of human embryos, so if you are interested, you can study it!"

Liu Wei said with a smile: "I don't know much about the knowledge of genetics, my teacher has a high attainment in this area, and I will ask him to introduce you in detail when I have the opportunity." ”

"Let's talk about the role of stripes, for the study of zebra stripes, there are great differences in various time periods, which also reflects the limitations of scientific research, after all, the times are advancing, and the level and direction of human cognition will change greatly.

In the early days of research, scientists believed that the stripes on the zebra's body were the main markers for mutual recognition between their kind, and they were also the protective colors formed by the zebra to adapt to the environment, which could play a very important role in defense.

The African savannah is a paradise for large predators, although the zebra has a strong running ability, but in front of the highly skilled cats and crocodiles, its defense means are still very immature, they will often quietly approach the zebra, launch a surprise attack, will not give the zebra much chance to react.

If zebras have a chance to escape from their attack, then the lines on their bodies will play a big aid.

In the open grasslands and deserts, these black-brown and white stripes reflect different rays of light when illuminated by sunlight or moonlight, which play a role in blurring or distracting the contours of their bodies, and it is difficult to distinguish them from their surroundings when viewed.

When the zebra escapes, it is easy to distract the predator, making it difficult for the predator to discern the target of the pursuit, and the predator may give up the hunt because of hesitation.

During World War II, the United States painted warships with colors similar to zebra stripes to blur the Japanese army's vision and confuse it.

However, in recent years, zoologists have found that the stripes on the zebra can distract and weaken the attention of mosquitoes and flies on the grassland, and effectively prevent mosquito bites. ”

"Damn, that's fine!"

"In the future, you don't need to light mosquito coils, just paint your body!"

"You're awesome! Remember to post a picture when the time comes!"

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

The audience burst into laughter.

The atmosphere in the live broadcast room is very harmonious.

After Liu Wei helped the zebras comb their hair one by one, he also sat on the ground and rested for a while.

Before the sun sets, the zebra herd will continue to rush forward, the speed of progress is not fast, Liu Wei did not ride up, with Pingtou and Chubby to follow.

It's getting dark.

The herd of zebras walks into the jungle and finds a safe place to rest.

Zebras sleep in a different position from other equine animals, and humans sleep standing on horses, while zebras sleep lying down, lying flat on the ground.

During breaks, there are still members of the group who are responsible for keeping watch on the periphery, and they take turns on duty.
