Speaking of which, Chinese people are really uncomfortable in Africa, and sometimes they feel both angry and funny.
At least that's how Xiao Peng feels now.
Say Africans are lazy?
In fact, it's really inaccurate, the most important reason is that they really don't have a sense of crisis, and they won't be in a hurry when the fire burns to the eyebrows!
Like Madagascar, there is almost no industry here, the level of industry is low, and there is also a lack of labor to work in the fields, so the land is very plated, so large tracts of land are discarded.
And the people here are very keen to cut down the woods, because the woods are cut down to expose very good humus soil for sowing, and the soil is very soft, poke a pit with a stick to facilitate sowing.
The development of agriculture due to this lack of industry is simply a frenzied waste of land.
Before the intervention of the Malaysian government in 2007, the local people cut down trees at will, including baobab trees, because the baobab trees are soft and suitable for hollowing out rafts, resulting in a large number of baobab trees being cut down.
Anyway, the baobab trees have been cut down, what if there is a famine?
They don't even think about it!
Many foreigners travel to Madagascar mainly because they think that Madagascar is the last unspoiled primeval forest park in the world.
But in fact, Madagascar has done a very poor job in terms of ecological and environmental protection.
Indiscriminate deforestation destroys wildlife habitats and kills wildlife indiscriminately for food.
The western side is fine, but the people in the eastern part go to hunt lemurs for food because they are hungry.
It is even sold to tourists as a 'special delicacy'!
Alas, it can be seen that the people of Madagascar are indeed hungry.
If you are poor, you will think about change!
From this point of view, the biggest enemy of the protection of the natural environment should actually be economic backwardness.
No one wants to do anything about environmental protection under the premise of being homeless without clothing, food, hunger, and homelessness.
Not long after a few people got out of the car, they were surrounded by a group of children, Xiao Peng thought he was here to ask for tips, but it turned out that this group of children were holding all kinds of chameleons in their hands.
Madagascar has three treasures: lemurs, baobabs and chameleons.
It is also a Malagasy specialty that tourists from all over the world talk about.
In fact, like the kangaroo country, Madagascar is an independent island country, and there are many animals here that are unique.
Xiao Peng didn't understand what they were talking about, and turned his head to look at Farah, who explained, "Mr.
Xiao, these children are taking pictures with you with these chameleons.
Five hundred ariaries each, and you'll have enough to do with them.
But I don't recommend that you do that, in fact, it will only cost 500 to 1,000 ariaries to buy a chameleon here. ” Xiao Peng whistled: "So cheap?
” Farah laughs: "In Madagascar, people don't miss any opportunity to make money!"
” Xiao Peng looked at the chameleon in the hands of those little guys, there were rose withered leaf chameleon, Osley chameleon, Pfeifer chameleon, Noor chameleon, Parson chameleon, etc., Xiao Peng even saw a little guy holding a mini chameleon in his hand!
Catch this little guy!
Good eyes!
You know, this mini chameleon, as the name suggests, is small, how small is it?
The longest plus tail is only three centimeters long!
Ordinary ones can even stand on match heads!
This miniature chameleon was discovered not long ago, and I didn't expect to see it here.
It is said that after genetic testing of this mini chameleon, scientists said that this chameleon means that its ancestors are even smaller, which is slowly getting bigger after evolving from generation to generation!
So how small could their ancestors be?
It's unimaginable!
Yang Meng took out the SLR camera that Xiao Peng was carrying: "Brother Peng, don't you take a picture with this chameleon?"
” Xiao Peng suddenly remembered the science magazine he had seen recently, and asked Yang Meng rhetorically: "Mengzi, do you know why the chameleon transformed?"
” Yang Meng was stunned: "Hey, you really think I'm an idiot?"
Elementary school students know that chameleons change color to adapt to their environment, and by changing color, they can blend in with the background, avoid predators or approach prey!
As long as the knowledge of animal camouflage or protective color is mentioned, the chameleon will inevitably be pulled out and walked around, how could I not know?
” Xiao Peng shrugged: "Then your knowledge base already needs to be updated." ” "Huh?
What do you mean?

Yang Meng didn't know why.
Xiao Peng said: "Although the body color of the chameleon can indeed play a role in concealing colors in some cases, such as green means that it lives in the jungle, brown means that it lives in the desert, etc., but they do not change their color in order to blend into the background, let alone switch their colors at will according to the environment. ” "What's that?
Don't make a fuss!
Are you saying that what we learned in school was wrong?
Yang's eyes widened.
Xiao Peng pointed to the red-based chameleon held by a black brother and said: "Of course, you see this chameleon, called the leopard chameleon, is the richest body color of all chameleons, but it can't quickly and accurately switch body colors according to the environment." ” Yang Meng was puzzled and asked, "Isn't it because of the environment that the chameleon changes its body color?"
So what is the reason?
” Xiao Peng explained: "There are many reasons why chameleons change their body color, the most important one is to regulate body temperature.
As we all know, this chameleon is a cold-blooded animal and does not have an automatic regulation mechanism like an endothermic animal.
Therefore, it is particularly important that chameleons can constantly change the color of their body surface. ” "Everyone knows that dark colors absorb heat and light colors reflect sunlight.
Chameleons know this, so they have also learned to control their body temperature by changing their skin tone, and when they feel hot, the lighter color will make it as cool as a bikini on a boat, and if they feel cold, the darker body surface will make them as warm as if they were wearing a sweet little padded jacket. ” "Now many people in China who raise chameleons as pets don't understand, why does my chameleon not change color?
In fact, the reason is this, temperature!
” Secondly, he has another important role in changing color, which is to serve as a tool for communicating information.
It is used to express one's intentions, such as courtship, demonstration, etc.
Although chameleons cannot make sounds like humans, they can express their emotions and sorrows through changes in body color.
Whether or not to show you its discoloration is also to see the chameleon's own mood. ” "Let's just talk about courtship, the chameleon's body color is particularly important.
Especially when two male chameleons want to pursue the same female chameleon, they will definitely have to 'compete for beauty' to win the hearts of the sisters.
In order to demonstrate, their bodies will take on a brighter color and are ready to fight, while the brighter the color of the chameleon, the more likely it is to win the fight, and the losing side can only turn brown and walk away. ” "And female chameleons and juvenile chameleons, because they don't have to grab sister paper to grab territory, so their color is far less gorgeous than adult chameleons, female chameleons generally rarely change color, only need to change their body color slightly to indicate whether they are willing to mate."
"If you think that the male chameleon who comes to courtship is not interesting, their color becomes dull to show rejection, and if you are pregnant, it becomes darker, as if to say, 'Don't go in, don't make an appointment', and your gray chameleon?
That's the female. ” Yang Meng frowned: "Isn't this chameleon's protective color not so godly?"
That's not interesting, right?
After speaking, he touched the chameleon held by a child: "This thing is also docile, right?"
” "Meek?"
Xiao Peng smiled, only to see it take out the mobile phone from its pocket, turn on the selfie mode, and aim at a chameleon, so that the chameleon could see itself in the phone.
Who knew that the chameleon, who was still lying there honestly just now, suddenly became emotional, became extremely excited, grinned for a long time, and rushed directly to Xiao Peng's mobile phone, wanting to attack himself in the mobile phone.
"What's going on?"
Yang Meng asked curiously: "I was honest just now, but now I have become so aggressive?"
” Xiao Peng explained with a smile: "Under normal circumstances, there are very few animal species that can recognize themselves in the mirror, and this chameleon itself is not intelligent enough, how can it recognize itself in this mobile phone?"
They thought it was another chameleon and a competitor to them.
If you have chameleons at home and want to make them lively, you just need to hold a mirror and put it in front of it, and everything will be done.
Watch it get excited every minute. ” Yang Meng gave a black brother five hundred ariarias, took the chameleon in his hand into his hand, and said to the chameleon: "Boy, give me a change of color!"
” Xiao Peng suddenly remembered something: "Mengzi, do you know how chameleons change color?"
” "Huh?
Do you test me?
Yang Meng scratched his head: "You can't trouble me with this question, there are layers of pigment cells under the skin of this chameleon, each layer of cells controls a specific color, and it can be reconciled into different colors through the relaxation and contraction of pigment cells, generally speaking, it is similar to the principle of the color display screen of TV."
What do you think?
It's not that I don't know how to learn, do I?
” Xiao Peng smiled and shook his head: "Well, the answer ------ is completely wrong!"
” "Huh?"
Yang Meng was stunned: "I remember that's what our biology teacher said." ” Xiao Peng scratched his head and said: "Our school textbooks also tell us that there are Eskimos living in the Arctic Circle, do you really call them Eskimos in front of them?"
I turn my face with you every minute, believe it or not?
” The Inuit are referred to as Eskimos in Chinese textbooks, which is actually a derogatory term meaning 'cannibal'.
If you call them that to the Inuit's face, isn't that the rhythm of looking for a beating?
"And how does a chameleon change color?"
Yang Meng asked.

Xiao Peng smiled: "In fact, the secret of chameleon's discoloration is not in the cell at all, but in the structure!"
” "In the biological world, there are two main sources of color formation------ pigment color and structural color.
Most of these plants and animals are pigmented in color.
Through the absorption and reflection of light to form color, our human skin color is a pigmented color; Butterflies are a representative of structural color, we see many butterflies are beautiful, but if the scale structure on their wings is destroyed, they will not be able to show their original color. ” The chameleon's skin has two densely overlapping layers of iridescent cells, which not only contain pigments, but also have countless photonic crystals that reflect light and emit color.
In other words, the chameleon's skin contains both pigment and structural colors. ” "Photonic crystals vary in size, shape, and arrangement, and take on different colors.
Chameleons control the arrangement of these crystals through the relaxation and tightening of the skin, and achieve body color changes. ” Yang Meng looked at the chameleon in his hand: "Its mood is normal, its temperature is normal, and its body is green, which means that this is a green chameleon, right?"
"The green chameleon is the most common of all chameleons.
Xiao Peng shrugged: "No, no, no, you are wrong again, this chameleon does not have green pigment cells in its body at all." ” "So how can it be green?"
Yang Meng was puzzled.
"You don't know the three primary colors?
The normal color of the chameleon's body is blue, but there are yellow pigment cells, and the blue and yellow together are of course green, and when the chameleon is nervous, they will actively control the density of the crystals, making them more loosely arranged.
Such structures emit longer wavelengths, so that as the void increases, the color changes from blue to green, yellow, and then orange and red.
Oh, and of course, there are chameleons that are originally red, such as leopard chameleons, but that's still very rare.
And this chameleon's iridescent cells are not only one, but still two, but that layer is not responsible for changing color, but is responsible for regulating temperature.
Now, scientists are creating materials that can change color and regulate temperature based on the chameleon's two layers of iridescent cells. ” Yang Meng scratched his head after hearing this: "Anyway, our Chinese textbooks are also cheating, right?"
Isn't this conveying misinformation?
What does this do with the kids?
” Xiao Peng said with a smile: "Science is advancing, and teaching materials are also improving, this is an inevitable trend, but it is just a matter of speed." ” Yang Meng looked at the pile of chameleons in the child's hand and sighed: "Anyway, this animal in Madagascar is really interesting, how great would it be if we could move all the animals here back?"
” The speaker has no intention, but the listener has the intention.
Xiao Peng's eyes rolled, but he paid attention.
I saw him pick up the phone and dial a number: "Hey, Brother Du, I have something I want to ask you for help。。。。。。
