Of course it's dinosaurs, I watched cartoons about dinosaurs when I was a child, and I really liked Tyrannosaurus rex at that time, dinosaurs have always been a mysterious existence in my heart, it represents the scene of the chaotic period of this world, and it is the first creatures on earth.
-
Dinosaurs, I think the dinosaur impressed me very much, first of all, its appearance made me feel that this animal is very large, and then its survival, which makes me think that it is a very amazing animal.
-
It should be a dinosaur, because another form of dinosaur makes me feel very impressed, that is, I feel particularly terrifying, and then I feel particularly burly, I make my special image profound.
-
It must be dinosaurs, dinosaurs used to be the overlords of this world, they enjoyed a unique advantage, the ability to be the masters of this world, and we know very little about them, and they are mysterious enough, so I am particularly impressed by them.
-
Dinosaurs impressed me the most, because when it comes to extinct species, the first thing that comes to everyone's mind is basically dinosaurs, everyone knows that before human beings, the species on the earth were dinosaurs, and now many museums have dinosaur fossils.
-
The Irish deer, the largest deer that once lived on the planet (extinct about 7,700 years ago), the Irish deer has a huge size, and it was also noticed because of its large size at the time, probably because of its strange appearance, so it is still very impressive.
-
Among the extinct animals, the most impressive is of course the dinosaurs, since I was in elementary school, I listened to the teacher, and all the people around me will say that the dinosaurs are extinct, and I don't see a lot of dinosaur-type cartoons.
-
Tyrannosaurus rex is one of the largest terrestrial carnivores, with a foot long, foot tall and an estimated body weight of 7 tons.
-
In fact, in the era when humans did not live, dinosaurs were the masters of this world, and they were very huge and ferocious, but I think their existence also promoted the development of the times.

The carved tooth beast, the big turtle among the beasts.
-
Carboniferous giant horses, ground sloths, sharp-toothed shield fish (Dun's fish), megalodon, hacking birds, brutal lions, short-faced bears, titan pythons, emperor crocodiles, dragons, and many more.
Most of the above lists are ancient extinct creatures with large bodies and brutal temperaments, and if you only say "terrible", I recommend almost all the creatures of the Carboniferous period, thank you.
-
Thankfully, a terrible creature that has been extinct.

When we watch the news, we often hear about species extinctions, but we rarely see new species being born. There are two main reasons for this situation, one is that it takes a long process for the emergence of new species, and the lifespan of human beings is very small for a species; The second is people's cognition, when we discover a new species, it is impossible to determine when it first appeared, and relevant research is needed. That's why, we can see the news of new species on the Internet, but we can't hear about the birth of new species.
1. Human life expectancy is very short, normal people's life expectancy is about seventy or eighty years old, and people with long life spans can live to more than 100 years old. This time is a long process for human beings. Especially compared to common animals, such as domestic animals, even if people do not slaughter them, they can only live for twenty or thirty years at most.
Flies and mosquitoes may only live for half a month or a few months.
It seems to have a long lifespan, but compared to the birth of a species, it is not an order of magnitude at all. When we talk about a species, it is at least hundreds of thousands or millions of years ago, and people have only been civilized for thousands of years. Unless there is a coincidence, it is difficult for humans to witness the natural birth of a new species.
2. The discovery of new species and the birth of new species Human cognition of the earth is very small, and many places where human beings are not able to fully explore, in this case, with the continuous progress of science and technology, we can occasionally discover new species. However, the discovery of a new species does not mean the birth of a new species. In order to know how long a species has been present, it is necessary to conduct various investigations of the environment and species.
In fact, technology has advanced to a point where we can discover new species, which is already a breakthrough. In order to study them, continuous progress and development are needed. In this case, it is difficult to determine the time of origin of the species.
In other words, even if people witness the birth of new species, they can't be sure.
3. Environmental Trends The current environmental trend is to protect nature, and some endangered animals will be specially protected. With the intervention of manpower, the living environment of animals has become better, and it is difficult to give birth to new species at this time.
The other is the impact of the environment, we look at some scientific research, every time a new species is born, it must be a catastrophe on the earth. When one species becomes extinct, another species emerges. With the current strength of human beings, the earth will not experience a huge catastrophe in the short term, which means that it is difficult to usher in the birth of new species.
If there is a catastrophe that destroys the world, humanity may not be able to survive.
-
That's because it takes a long time for new species to be born, and if people find out, they don't feel like they're new species born.
-
Because it takes a long time for a new species to be born, and the time of human civilization is not very long, it is difficult to see.
-
I have heard of species extinction, but I have never heard of the birth of new species, this is because animals and plants are gradually dying out at an incredible rate, and in general, human beings have encroached on their homes, and environmental pollution is caused, so we must pay attention to protecting the environment now.
-
Because we humans are very serious about the jurisdiction of animals, and each region will have a special person to watch over the animals, the chance of a new species being born is very small.
-
Because the birth of new species in the ecological chain is generally difficult to find, and many people do not study it, there is no such statement.
-
Because it takes a long process and a stable ecological environment for the birth of new species, but now these requirements are not available, so I have never heard of the birth of new species.
-
In our lives, we often hear about species extinction, but we rarely hear about the birth of new species, which has a certain reason, and it also has a certain scientific basis, so let's introduce it to you.
First of all, we must know that in ancient times, we can often hear about the extinction of a certain species, such as dinosaurs, etc., the extinction of dinosaurs was in our ancient times, and we have not heard of the birth of new species until now, we must know that it is often very difficult to be born after the extinction of a species, because this kind of species has completely disappeared, and it is impossible to be born again, to know that a new species is evolved from the original species, to put it simply, when the species of the object wheel is extinct, There may be one or two that are still alive, so that a new species can be born from this small number of original species, and if the original species becomes extinct, it is impossible to create new species. The second is to know that in life, because of the living environment or diet, or some other reasons, there is isolation between populations, so the habits and personalities of different species living in different regions are different, and at the same time, they all start, and their different evolution will lead to the elimination of some species, while other species are survived.
You must know that chimpanzees are a relatively common animal in our lives, but there are many species of chimpanzees, if a certain species of chimpanzee is extinct, it is more difficult to regenerate, and the tiger is well known in our life, it is the king of the forest, but there are many species of tigers facing extinction, and it is more difficult to be born.
It can be seen from this that there is a certain scientific basis, and there are also certain objective facts, so we must protect some of our rare animals in life, if once extinct, we will no longer see their beautiful appearance and some of the benefits they bring us.
-
This situation is due to the fact that biological evolution has reached a high level, so species extinction is a common thing, and the birth of a new Zhaoshen species is a very difficult thing to meet Wang Chai with.
-
Because it is impossible for new species to emerge in the current situation, and the development of the earth is always changing, the emergence of new species will be relatively rare.
-
Because the conditions for the birth of new species are very harsh, no new species will be born for many years, and these species will not be easily discovered.
-
From a biological point of view, the birth of a new species is the formation of a population, then the formation of a category, and finally the formation of a species, which takes a long time in the middle, and cannot be observed by one or two generations.
But this does not prevent us from verifying the correctness of the theory. Just look at the dog, the dog was domesticated by the wolf, and now countless populations have been formed, the Chow Chow Demu Erha, each of which can be inherited traits, and can also reproduce, it can be said that it has transitioned from the population to the category, and then the development of different dog breeds will produce reproductive isolation, which can be completely defined as a new species (by the way, reproductive isolation is not the standard for defining species, there is no reproductive isolation between the lion and tiger but belongs to two species).
There are more new species in plants, but they are not so famous and unknown to the general public. New species are born, but the time period since we have recorded them is too short, and there are always new mutations, such as many new bacteria, viruses, symbionts, and large populations are not enough to appear obvious new species due to time relations, and it takes a long time for the new species to stabilize.
In order to adapt to the environment, subspecies constantly appear. After all, human beings have a very short understanding of the world, so quantitative changes have not yet caused qualitative changes. In fact, there are really a lot of new species born, many of which are actually no different from the old species, but as long as there is reproductive isolation, it is called a new species, and now it is known that there are many, many new species cultivated by artificially, and then because of the current ecology, nature has also evolved a lot of new species, but the extinction of old species is easy for us to detect, and the emergence of natural new species has to wait for us to discover, so there are relatively few mentions, but definitely a lot.
It is certainly easier to hear about the extinction of a species than it is to hear about the birth of a species, because it is also the extinction of the species that people are concerned about rather than the birth of the species, especially in today's situation of environmental degradation due to human activities!
Finally, not to mention the tens of millions of species on Earth today, can you name a thousand species? A thousand won't work, what about a hundred? It's also hard to estimate! So, here's the problem, not many people really care about the birth of a new species!
-
Because the current natural environment is not suitable for the development of new species, and the places suitable for animals to live are getting smaller and smaller, few new species are born.
-
It's because it's rare for some new species to be born, and it's often not called a new species birth, and in general, if some species are born, then there is also a mutation, so there is no such thing in general, and there will only be some species that you also feel expressed.
-
This is because the number of this new species is relatively small, and this new species has been protected by professionals when it was first discovered, and it will not affect their normal life.
-
Mainly because even after a new species is born, we don't know it, because we don't have this concept, but most of us know about the extinction of these existing species.
-
Because it takes a long time for new species to be born, we can't see it, and we are constantly discovering new species.

Da Vinci password In the first level, I found a combination lock, but I didn't know which four English letters it was, thinking it was a profound password, and I needed to find clues in that small room, so I started to search every corner. It's hard to find! Later, it really didn't work, WeChat asked the owner, he, unexpectedly, dared, to tell me, password, that is, game !!
After falling in love, my partner would confess to me once a day, and make a promise to me, telling me that I was the person he had been waiting for all his life, and that the two of us would definitely get married in the future, and every time I heard such words, I would be overjoyed when I heard such a promise, and I felt that I was the happiest person in the world.
Falling in love is a very good thing, after all, just like Zhang Yu's lyrics wrote, it must be a special fate to become a family along the way, but there will definitely be contradictions and even quarrels when falling in love, so at this time people will be confused in love, how does your object make you sad? In fact, the main thing is not to understand, especially when doing thingsA lot of times it's just thinking about yourself, not thinking about reality, and a lot of times reasoning is a long time to talk about, which really feels like a waste of time, let's analyze it in detail. >>>More
