This is because Ling Xiao knows that the bananas that humans like to eat very much are not naturally evolved fruits, but fruits specially selected by human researchers and specially crossed by a variety of plants, and this kind of directional cultivation of bananas is very popular with humans.

Because this fruit is fragrant, sweet and soft when ripe, it can be said that it is loved by most people, men, women and children. Bananas are not only a delicious fruit in the eyes of most people, but even in some parts of Africa, bananas are the staple food of human beings, feeding many people, which shows that bananas have contributed a lot.

The reason why the sweet banana is delicious is that the taste is soft and sweet, sweet but not greasy, on the other hand, there are no seeds, you can eat it in one breath after peeling off the skin when eating, you don't need to spit out the seeds in the middle, it is convenient and fast, and it is quite delicious, and generally does not hate this fruit, and a lot of food with bananas as the material has been developed.

Bananas are seedless, which is a good thing for diners, because it saves trouble and effort when eating, and is definitely one of the most convenient fruits to eat. But for the banana plant itself, it's a different story.

Of course, it is said that the banana is seedless, and it is not all right, in fact, there is still a little residue of seeds, and the only part that can be counted as seeds is something brown in the flesh, that is, the degraded seeds, which are not ripe at all, and completely lose the function of reproduction.

So without banana seeds, there would be no seeds that can multiply bananas, and supposedly this fruit would not be able to multiply, so how did researchers make banana cultivation spread all over the tropical regions of the world?

Because the researchers are very clever and use a kind of asexual reproduction, each new banana tree grows from a part of the old banana tree, and the bananas in the world are considered clones of a banana, and their genes are exactly the same.

In this case, people can eat bananas that feel similar to the taste, and they have become one of the favorite fruits of many people. However, because it is impossible to reproduce by seeds, bananas have been propagated with similar cloning properties, and the homogeneity of genes eventually leads to a question: will this banana be completely wiped out?

Because bananas in the whole world have always been a gene, so once the banana encounters a natural enemy, all banana trees will not be able to resist this natural enemy, and a bad one is the end of total destruction, and this is not alarmist, it has happened once in the banana world.

The banana that human beings eat is actually called the banana, and before it there was a larger, sweeter and more fragrant banana variety Da Mike is the banana that people eat, which is said to be more delicious than the current banana, and its fragrance is as good as the banana flavor now.

But who made Big Mac also have only one gene, and after a Big Mac was destroyed by a fungus, humans couldn't defeat that fungus. Bananas all over the world were eventually destroyed by fungi, and even the fungi in the land where Big Mac was originally grown could not be grown for decades.

After Big Mac was exterminated, fortunately, there was a spare variety of Chinese banana at that time, although it was not as big as Big Mack, and it was not sweet enough or fragrant enough, but it was better than no banana in comparison, so Hua Jiao replaced Big Mac and planted all the places that could be planted.

But the incident of Big Mac has sounded the alarm bell for people, because banana cultivation uses vegetative reproduction, which belongs to cloning again and again, which is to embark on a road of no return, because they are all the same genes, and no one can run away once they get sick.

Although the development of science and technology has allowed people to win again and again in the battle against bacteria, fungi and viruses, it does not mean that they can always win the war against bacteria and fungi, and many times human beings have lost many times.

In fact, while human science is constantly advancing, bacteria, viruses, fungi and other organisms are also evolving, such as the emergence of superbugs, and the emergence of malaria in Africa, and even viruses are mutating.

In the battle between Big Mac and the fungus, humans also participated in the war, but in the end they did not save Big Mack, this is a case of failure, which is basically a warning from nature to humans.

The same banana will one day face the same situation as Mike, a fungus and other organisms that it can't resist will make the banana completely extinct, because it has no genetic diversity, if one banana is infected, then the whole world will be infected, and the only way now is to guard against it.

Well! After Ling Xiao knew about it, he felt one thing: it really needs to be paid attention to the genetic diversity of various plants and animals, so the pair of animals in Noah's Ark can't guarantee that the animals will be able to reproduce, right? Because the gene is too single, it is very likely to be eliminated.

Also, don't do all the asexual reproduction, let's do some sexual reproduction! In this way, the variability of genes is guaranteed, because a gene will ensure that the species can reproduce.

It may seem that the genes are not perfect, but when something goes wrong, it will not wipe out all the species, and genetic diversity will allow some organisms to escape when disaster strikes.

Just like rice, many rice will have lodging phenomenon after the wind and rain, which will eventually lead to a large-scale yield reduction, some rice will not work, and some will survive, pass on the lodging resistance gene, and become a lodging resistant variety, which is also the benefit of genetic diversity, there is always an advantage to show.

In addition to the Big Mac banana extinction incident, there was also a time when a certain country had grown a variety of potatoes for many years, and finally the potatoes were cut out, resulting in many people who thought of potatoes as a staple food starved to death.

In fact, there is also a problem with potatoes, in many cases, potatoes are not planted using sexually propagated seeds, in fact, how do people grow potatoes?

Generally, the tuber of the potato should be cut into several pieces, and the sprouts on the small tubers should be planted, so that new potato plants can come out, so that the reproduction of potatoes and bananas is very similar, and there will be an outbreak of illness, and the potatoes will be completely finished, and it will also cause people to starve to death.

After thinking about the evolution of bananas, Ling Xiao was a little puzzled when she saw a tree similar to bananas, because she didn't know if she could eat it? Wild bananas that have not been cultivated in the mortal world are not good at all, because the fruit is full of seeds.

Even if you wait until the fruit is ripe, you won't like it very much, and if you bite into it, you will find that there is very little meat, almost half of it is seeds, and basically you don't want to eat wild bananas.

In fact, the delicious fruit is the result of the evolution of plants for the reproduction of the race, and many animals that eat the fruit will eat again and again because the flesh is delicious, sweet, and nutritious, and it is possible to eat the seeds in the process.

It's just that the seeds have the protection of the husk and will not be digested, those animals can't digest the seeds at all, and then they will pull them out, and the seeds can still germinate, and how far the animals go, then how far the seeds can go, then the pulp strategy that the plant has evolved is successful.

And this mutually beneficial behavior is conducive to the reproduction of plants, and the plants will grow enough and delicious enough fruits to attract animals, so that enough seeds can be taken away from the mother plant, which greatly ensures that the plant population will grow more.

The same animals will also like to eat better and more nutritious fruits, because eating them will make the animals in the population stronger, and they will have the ability to fight against other populations and natural predators.

In this case, it is a win-win situation, the delicious and nutritious fruit ensures that those animals are more competitive, the animal population will have more kindred, and there will be a larger territory, so the seeds of the plants will follow to further places.

In this case, it is a win-win situation, then this plant will naturally make its flesh delicious and become the right direction of its own evolution, because it attracts more diners, and the increase of diners means that more seeds go to distant places, and the population will grow in large numbers.

Plants with unpalatable fruits will gradually become less attractive, and they may not be able to attract more diners, resulting in seeds growing in the vicinity at most, reducing competitiveness, and gradually being eliminated.

This is the survival of the fittest after the animals and plants have chosen their own evolutionary direction, the correct evolutionary direction allows them to reproduce, and the animals and plants that cannot adapt to the wrong direction will become extinct, this is natural selection, the survival of the fittest.

As a plant organism, in the direction of evolution, in order to reproduce, nature hopes to have more seeds, can go to more places to live, maybe they do not adapt to the new environment, will die halfway, and even some seeds can not wait for the opportunity to germinate and die, but as long as a few successes.

In this case, Ling Xiao will feel that the plant that looks like a banana is not the banana in his imagination, and believes that wild bananas will not forcibly make seedless bananas like humans, how can seedless bananas multiply everywhere? Seedless bananas completely sacrifice the chances of the banana plant race to reproduce itself.

After arriving at the place, she went down and found that there were some small animals infesting that place, Ling Xiao took a look, and felt that these plants should be edible, but if she picked them in large quantities, would they not survive?

She couldn't let other animals have enough food because of her own whimsical thoughts, and after thinking about it for a while, she decided: even if it is delicious, she can't pick too much, or don't grab food for the small animals.

She picked one of the highest places to try, and after eating a bite, she found that it was not too delicious, not that the flesh was not delicious, but because there were too many seeds, if you didn't pay attention, you might break your teeth, so what else was delicious?

Sure enough, it was not a delicious seedless banana, Ling Xiao didn't want to eat it anymore, of course, she didn't think about researching seedless bananas, obviously normal bananas have seeds, and they can reproduce on their own, instead of needing human intervention.

Maybe every day there will be a genetic mutation and the real banana will appear, because anything is possible, so there is no need to castrate the banana for your own liking, or just let it grow like this.

Ling Xiao didn't pick the banana, and he wasn't disappointed, although he couldn't eat it, but the wild banana was also very good, looking at the banana in his hand, he wanted to laugh a little, because this banana was very similar to a wild fruit.

To put it mildly, the current banana looks, if the flesh is a little more transparent, like a fleshy bug, no matter how you look at it, it looks a bit like the wild August melon, in fact, I remember that the August melon is also called wild banana in some places.

Ling Xiao left here and continued to move forward. I found a lot of good things along the way, and I was especially surprised to pick up a lot of things that are very good for mortals, such as gemstones, and they are pure natural gemstones.

At first, she hadn't woken up, thinking it was that kind of colored glass, but when she remembered that it wasn't glass at all, she picked it up and looked at the light, those unpolished gems didn't have any light, but they were very transparent, so it was better to wait and polish them later.

She wondered how to polish the gemstones, and then she thought that she was a monk now, and polishing this would be a piece of cake. When I was looking for other places, I paid attention and found more gemstones, all of which were colorful and good materials.

Later, she played with nothing and found that the gems found in the demon world were clearer, Ling Xiao took a look and felt that the hardness of the gems in this place was not low, hey! It's really good, and it can be used as an exchange thing for money in the future.

At that time, she practiced for a while, just planning to relax, feeling a little idle, remembering the headdress she had seen, and remembering that someone specially imitated the queen's phoenix crown, she had some itchy hands, so she specially made a phoenix crown of real money, and after making it, it looked really magnificent.

Wow! It's definitely very valuable, but it's also very heavy to try it, wearing these things can be said to be dozens of pounds on the head, as well as special dresses, and special accessories on the body, I feel that the weight is not light, I just need someone to help me to walk, this ancient lady is not good.

Later, in her free time, she made other beautiful accessories, and she also knew that it was best to make these things without leaving too many personal traces, so as to prevent some people from directly recognizing that they were not products of this planet.

In addition to those gems, when she was about to reach the mountain, Ling Xiao encountered a river, remembered that there might be fish in the river, so she was ready to go fishing, the river water was very clear, she squatted down to test the water temperature and found that it was very cold.

You must know that the temperature around us is not low at this time, but the river water is obviously much lower, and it should be so low after the snow on the mountain melts, but I am afraid that there are not many fish, because the water temperature is too low.

Ling Xiao saw that there were more pebbles in the river, so she picked them up, but when she got them in her hand, she felt that this pebble was not an ordinary stone, but a so-called jade material.

She began to collect a lot of stones, and then violently rubbed the stones, and found a lot of good white jade, or that kind of mutton fat jade, which made her feel very happy, so she continued to search, and while looking for it, she removed the stone on the outer skin of the jade and reduced the weight.
