The next pavilion area of the colorful lizard is the giraffe pavilion area, this pavilion is Qu Lihua's favorite area, the characteristic is that the giraffe is deeply impressed, the giraffe is also a very distinctive animal, Robin took everyone to see the giraffe.

"Let me introduce you to the giraffe, you just know some ordinary giraffe knowledge, not know more knowledge in detail, I think it is still necessary to introduce, according to different genes, giraffes can be divided into 4 independent species, namely the southern giraffe, the Marseille giraffe, the reticulated giraffe and the northern giraffe, two of which have been endangered. ”

Giraffes inhabit the savannahs of central, eastern and southern Africa, while the four species of giraffes, southern giraffes, Masai giraffes, reticulated giraffes and northern giraffes, inhabit different parts of Africa and do not interbreed in the wild. ”

Listening to Robin's introduction, Qu Lihua was immediately interested, every time he came to a place, Robin explained to everyone, there are famous scenic spots, there are also humanistic feelings, Robin is knowledgeable, knows everything, nothing is difficult for him, sure enough, it is Dean Zhang's graduate student, Qu Lihua still admires Robin very much.

When encountering knowledge points that she doesn't understand, Qu Lihua will humbly ask Robin for advice, and Robin will also answer all questions.

"Robin, do the giraffes look similar, the same size and color?"

Robin shook his head, "Giraffes are different in size, color and fur texture, just like us humans, Asians look similar, but if you look closely, they are different!"

"Northern giraffes and reticulated giraffes are scarce in number, belong to endangered large mammals, and have high conservation value, and the biggest threats faced by giraffes include population growth leading to giraffe habitat destruction and human hunting, in the last N years, the number of giraffes on the African continent has declined sharply, from 150,000 to less than 100,000, and perhaps this number will gradually decline, so it is necessary to protect animals, animals are good friends of our humans. ”

"Protecting animals is also being kind to us human beings, if human beings pollute the environment excessively, regardless of these animals, animals will be on the verge of extinction, and to a certain extent, it will also threaten the survival of human beings. ”

"Although human beings are very smart, but sometimes, they will ignore the long-term interests because of short-sightedness, protecting animals, protecting the environment, is our human responsibility, but also our mission, if the environment is polluted, animals are dying, the earth's ecology is seriously damaged, human beings will also face a crisis. ”

"Let me introduce you to the characteristics of giraffes, and how giraffes protect themselves in the face of fierce beasts!"

"I'm sure you've all seen Animal World, and there are a lot of shots in it about how giraffes protect themselves when they face predators!"

"Yes!" Qu Lihua nodded, "I've also seen it, I remember it very well, and I'm really worried about the giraffe, I don't know how it protects itself?"

Robin nodded, smiled, and continued to introduce: "Although the giraffe has a long neck, like most beasts, it has only 7 cervical vertebrae, its stride is long, it can reach 48 kilometers per hour when running, and its eyesight, smell and hearing are very keen. ”

Qu Lihua nodded, "Whenever I see such a picture, I feel very excited, I still like giraffes, I always think that it looks cute, it doesn't seem to hurt other animals, and eats leaves slowly, but it is still a nasty beast like a lion to bully the giraffe, and then I saw that the giraffe launched a counterattack without hurry, and kicked the lion with his hind hooves, and the lion could only let go and run away!"

Meng Wenjie was also interested, and interjected and asked: "The giraffe in the zoo is an animal that people love to watch, and many people probably want to ask such a question, why is the giraffe's neck so long?"

Robin said: "This is the progeny of animals, after a long period of hundreds of years, some even thousands of years, tens of thousands of years, animals have evolved and evolved, and they have adapted to the environment, and they are also their own genes, which have evolved from their ancestors." ”

"In the animal kingdom, the size of the giraffe is one of the best, the female is generally 4.3 meters tall, the male is generally 4.6 meters - 5.5 meters tall, and the tallest can reach 6 meters. ”

Of course, this is due to its long neck, which accounts for more than half of its entire height, but in fact, its long neck structure is nothing special, only 7 cervical vertebrae, which is characteristic of giraffes. ”

Darwin believes that there are two kinds of giraffes in ancient times, such as long necks and short necks, both of which feed on grass and eat the leaves of trees, and later due to the dry climate, the grass on the ground has died, and the low shrubs have also died of drought, so that they can only feed on leaves. ”

"Those with long necks survived because they could eat easily, while those with short necks died out because they couldn't eat the leaves from high places. ”

"Darwin's principle of 'natural selection, survival of the fittest' still seems to make sense now, so giraffes have such long necks just to adapt to the environment, they feed on leaves, so they have to have long necks. ”

Robin nodded, "There are also many biologists who have put forward different opinions, and the French biologist Lamarck believes that the area where the giraffe's ancestors lived has become an arid zone due to changes in natural conditions, and the grass available for survival has become extremely scarce. "Giraffes start with short necks, and in order to survive, they have to take leaves from tall trees to feed their hunger, and to achieve this, they try to stretch their necks, because the organs they use regularly become more and more developed. ”

"Acquired traits can be inherited, and so on and so on, and after thousands of generations, their necks gradually become longer, and finally become what they are today. ”

"Although some scholars have raised doubts, I think there is still some truth, not necessarily all right, but there is some truth!"

After watching the giraffe, Robin took everyone to see the alpaca, the cutest thing is that he also gave the alpaca a cute name, Qu Lihua smiled and posed for a variety of actions and took an intimate photo with the alpaca, and the alpaca came directly to her, feeling magical, not afraid of people at all, as if he had adapted to this environment, Meng Wenjie didn't believe it, so he tried it himself, and he really came over. "Hahaha, it's so cute, cute, not afraid of people at all!"
