There is a joke on the Internet that spoofs the giant panda, saying that the panda "has a mouth bite second only to the polar bear, and the eight bear families rank second; they can climb big trees in the sixth month of their birth, and play at a height of 20 meters; they are born to be proficient in mountain warfare, and they are proficient in mountain warfare, and they race Liu Xiang through mountains and mountains; they have big waists and round claws, and tigers and leopards dare not bully when they see them, and jackals see them with their tails running; such a creature actually makes a living by selling cuteness!"

However, this is just a lie made up by jokers to deceive ignorant netizens to like and collect and forward him. The combat power of pandas is far less powerful than this passage says, their bite force is indeed very high, second only to polar bears and brown bears, but the eyesight is very bad, no matter how high the attack power is, the hit will not work, and the combat power of the old fan SS will naturally fall down.

What's worse is that the panda's thyroid hormone secretion is insufficient, resulting in a slow metabolic rate, which is manifested in behavior that is slow and does not like to move, especially the pandas in captivity in the zoo, because of the regular feeding relationship to eat and drink more lazy, often stay in the tree or climb the frame for several hours without coming down.

In fact, this is all caused by bamboo!

Although the giant panda looks round head and round head, the round figure is very material, but in fact it is all an illusion, the hair on the body surface of the panda can be as long as 10 cm, and the hair is hard and can stand up, and the body size is stretched up twice, in fact, this is all fat in the fat, the body fat content of the panda is very low, and the body is actually covered by the cat's body hair. Captive panda cubs often perform "bone shrinking skills" in front of surveillance cameras, drilling through the gaps in the fence that look narrower than its body to the naked eye, because this body hair deceives everyone's eyes, not "bone shrinking skills", but the bear hair has enough elasticity to be squeezed to lodging down to reduce the volume.

Using long fur to "modify" the body shape to "enhance" combat effectiveness is not the patent of pandas, and it is actually the male lions on the African savannah who play more slippery. The lion kings are somewhat similar to armed security guards and breeding machines, on the one hand, they are responsible for driving away the prey of the defensive class hyenas, and on the other hand, they have to fight other stray male lions, and the price of defeat is that their wives are returned to other lions, and all their offspring are bitten to death. The manes on the back of their heads and necks can strengthen the defense of their necks and prevent them from being carried away by a wave of other lions and spotted hyenas' neck-biting skills, while the mighty and domineering long hyenas combined with the mighty roar can sometimes play the role of "surrendering soldiers without a fight".

In addition, the important cuteness of the panda, the pair of extremely eye-catching black circles were not originally for the "big eyes cute" and existed, the dark circles are also to enhance deterrence, used to scare off other opponents, after all, pandas have limited endurance, and cherish the hard-won energy very much, and it is naturally best not to fight without fighting.

In fact, in the process of more than 2 million years of evolution, giant pandas have formed a set of physiological mechanisms and life patterns that "bamboo-eating animals" should have. Because bamboo is not nutritious, it needs to reduce its metabolic rate to accumulate every penny of energy as much as possible, although the giant panda does not hibernate, its thyroid gland is as big as the hibernating black bear, and the metabolic rate of the active panda is even lower than that of people lying still.

Metabolism is a collection of complex biochemical reactions that cannot be measured directly, but because reactions are exothermic and affect the body's body temperature, indirect calorimetry can be used to measure it indirectly. Using the instrument to monitor the hourly heat generated per square meter of skin when the subject is at rest, it can be concluded that the "basal metabolic rate MBR" is used to measure the metabolic rate, which is 20% to 80% higher than normal in patients with hyperthyroidism and 20% to 50% lower in patients with hypothyroidism.

Therefore, the whole family of pandas is hypothyroid.

Similarly, pandas' eyesight, grip strength, bite strength, and eating habits are all matched to the living environment of bamboo forests, and their reproductive mechanism is also matched to the nutrients of bamboo.

Pregnant in spring and giving birth in summer, female pandas still have time to find bamboo to supplement nutrition, unlike the giant bear of the bear family, the calf is in the snow cave in winter, the female polar bear relies on the fat on the body not to eat or drink to feed the cubs, until the beginning of spring will take the 3 or 4-month-old cubs to climb out of the snow hole.

It is said that the brown giant panda "Qizai", the owner of the famous panda family color photo, was "rescued" down the mountain by taking advantage of the female bear when she was a cub to go out to eat and put it in a back basket.

Because there is not much fat on the body, lactating female pandas often need to leave their cubs out to eat, and then return to the tree nest cave to feed their cubs, and this period is also the most vulnerable period of the panda's life, often eaten by alpine predators such as the snow leopard ferret (yellow-throated marten). After six months when the cubs have mastered the skills of climbing trees, the pandas basically have no natural predators, and only their bodies and habits are left to make them difficult.

Because bamboo is less nutritious, each panda needs a huge foraging range, so adults must live alone, develop their withdrawn and cold personality, only in the mating season will follow the guidance of genes and hormones to find the opposite sex, but it is only a hasty three or four days to get it, if you live far away may not arrive at the meeting place hormone levels will decline, naturally lack of interest and lack of desire, which is the main culprit of the declining number of pandas.

"The so-called human activities have caused a drastic decline in pandas, which is completely wishful thinking of some environmental groups," said Ma Atletico, leaning on the edge of the log railing, "North American bison, Asian elephants, baleen whales, sperm whales, which once occupied land and sea, are really endangered by human activities." The panda, on the other hand, is not, and is an endangered species in its own right. ”

"You are quibbling! It is true that the land has been divided into thirty or forty protected areas, which are not connected to each other, hindering the exchange of genes and causing the population to degrade......

As the flagship species in the field of animal protection, the giant panda is the species with the most protected areas and the best protection resources, but the growth rate of its population is still very slow, and she has to admit that there is really a congenital defect of "being easily endangered".

Flagship species refers to the kind of wild species that are easy to attract public attention, and are often put out as signboards to attract investment projects, such as the giant panda red-crowned crane white-sided dolphin, which are popular animals such as flagship species, and they are also "umbrella species", and the protected area pulled up in their name also provides shelter for other wild animals. Just like Atletico Madrid, where they are at the moment, Panda Valley has attracted a large group of golden monkeys to settle here.

Thinking of the cigarettes on the way, Atletico said: "In the final analysis, it is still the trouble of eating bamboo, a good carnivore does not eat meat to concentrate on vegetarianism, and also develops a picky eater, no wonder the number of people is recovering so slowly." ”

"In fact, those golden snub-nosed monkeys are also endangered species, but they are all a family group activity, and they usually can't see it, and when they see it, they are thirty or fifty, so they seem to be a lot of people. ”

However, Tang Jiayi also felt very helpless about the eating habits of giant pandas, "Hey, specialized evolution and single-minded recipes are not good, and they are easy to go to extremes." It is certainly refreshing to eat with an iron bowl of rice, but when the environment changes, it is also not as adaptable as those omnivorous diet and a wide range of animals. ”

Specialization and degradation are both special phenomena in the process of biological evolution, although not mainstream, but not uncommon. For example, the palm of a panda has six fingers, and the "thumb" that can be held opposite the palm of the hand to grasp the bamboo pole and bamboo leaf is a typical specialized phenomenon. Bears have five fingers and the five fingers are in the same direction, so polar bears, black bears, and brown bears can only use the "big slap" to greet their prey and opponents, and can only hold them with both hands when grabbing things. However, the sesamoid bone on the flexure side of the giant panda's palm has undergone specialized evolution and has become a sixth "finger", a finger without joints that allows them to easily grasp bamboo poles and branches. The juvenile giant panda's super tree-climbing ability also has a great credit for this "sixth finger".

In a word, giant pandas have been on the path of "eating bamboo, eating bamboo better" in the evolution process of millions of years, and their various living habits also match the situation of bamboo, a staple food. Although compared with woody trees, bamboo has the unique rapid growth advantage of herbaceous plants, but compared with other herbaceous plants, it is nothing, and other herbaceous plants usually have a large number of seeds, with the help of wind and animals with hundreds of children and thousands of grandchildren to expand the efficiency of the territory, but also more than many times faster than the bamboo whip through the ground to expand the territory, plus the foundation of panda carnivores causes them to waste food very much, the number of pandas naturally does not rise. In modern times, the intensity of Chinese development of mountains and forests has increased, and the already small number of pandas has easily collapsed, and it will soon become an endangered species.

However, Tang Jiayi also thought of a piece of evidence to refute Atletico Madrid's "bamboo harms bear theory", that is, the Andean bear (eye bear), an American relative of the giant panda.

Although giant pandas and red pandas are called pandas, red pandas (les-colored rpanda) are not actually relatives of the rolling pandas, they are actually relatives of crisp noodles (raccoons). Among the living animals, the closest to the giant panda is the spectacled bear.

This bear has a black body, white stripes on the chest and face, and looks like a black body, white face and dark eye circles, and their dark circles look bigger than those of giant pandas, but the patterns are not as stable and smooth as pandas.

Spectacled bears are also alpine creatures, found in the narrow Andes Mountains of western South America, they are omnivores with a predominantly vegetarian diet, although they also eat bamboo, but prefer to eat nutritious fruits such as pineapple cactus, sometimes nibbling on corn, sugarcane honey, and occasionally a rabbit, and even American tapirs (pig-like with a longer snout that can roll things, but not as long as an elephant) and cattle and sheep will also be on their diets. The abundance of food sources has given spectacled bears a higher fat content and a larger number (about 20,000), but their survival status is actually only slightly better than that of their Asian relatives, the giant panda, and they are a vulnerable species that is slightly better than the endangered species.

"In the final analysis, most people are face-looking Yan Dang, not only for us humans to judge people by their own appearance, but also for wild animals," said Atletico Madrid for Tang Jiayi's counterattack.

Although the spectacled bears are about 10 times more numerous than the giant pandas, their numbers are decreasing year by year, partly because of their equally low reproductive efficiency, and partly because of the fact that the bears often die. Because the spectacled bear occasionally attacks livestock and steals crops, farmers in South America hate it so much that they shoot it when they see it. As for the problem of the farm and pasture being opened to the edge of Xiong's house, few people paid attention to it.

Even though the spectacled bear has its own sanctuary, public attention and protection are far behind.

is also mild and vegetarian, and also has a pair of big dark circles, but the popularity of the spectacled bear is several grades lower than that of the panda as well as their appearance.

Stretching out his hand and pointing to the panda that was tired of gnawing bamboo not far away, and rolled downhill to drink water, Atletico said with a smile: "If the spectacled bear can beautify that spectacled face, and then learn the stunt of rolling with his head and rolling, he will definitely be the enemy of the rolls." ”

"I think you're the enemy of the rolling people, there are not as many people who watch the real panda as there are to watch the fake panda tree climbing competition, is the world swollen?"

Along the way, the two of them saw fewer and fewer tourists, most of them stopped at the outer robot panda performance area, and there were not many tourists here in the innermost real panda.

In fact, this is also normal, as long as you compare the behavior of the "pandas" on both sides, you can see it, this one has been eating and eating since Atletico Madrid, and finally sold a cute 1080 degrees forward roll, and as a result, after sliding downhill and drinking water, he lay on the side and did not move. It's not completely still, and after a while, a ball of blue-green poop will fall from behind and hit the ground, which hurts the image very much.

On the contrary, the fake pandas who are competing to climb the tree are more active, funny, and cute, and the eye-catching index is naturally high.

These robot pandas are already the second generation of products, their power system has been improved, and they have also mastered the panda's tree-climbing skills, and the AI algorithm has also been optimized with reference to the real panda, and the "bear-likeness" is very good, and various cute poses are shaken out in turn.

Of course, the park did not emphasize the attributes of the robot cat is also one of the reasons for its popularity, although it was exposed to fraud and added a description board, but it was very hidden and uninstructed, and it was absolutely impossible to find.

In response to his wife's accusations, Atletico Madrid was heartening: "Pandas should have returned to the wild, domesticating pandas like Panpan is actually hurting them, and this kind of suffering should be borne by our robot cats! ”

"I hope so, but people don't necessarily want to. ”

In fact, the two of them actually didn't earn a penny in the panda industry, and all the proceeds were donated to the "Panda Corridor" project to communicate various reserves, which is also where Atletico Madrid's confidence lies in the face of media questioning.
