Human immigrants meet dinosaurs.

There are countless extinct animals in Qian Qian, but human children seem to have a soft spot for dinosaurs. They are also extinct animals. Mammoths, saber-toothed tigers and dodos are not as popular as dinosaurs.

Now, according to paleontologists, not only the extinction of dinosaurs is a mystery, but also the obsession of human children with dinosaurs.

In primitive society, there were mammoths in human paintings.

As we all know, human children have some "natures". For example, they like to shake branches when they go to the Woods, and they want to climb up if possible. In other words, although we are out of the forest, we still like to be close to the forest and climb trees. These "natures" are manifested in children who have not been decorated by human culture.

So, children like dinosaurs, does it mean that human ancestors once lived with dinosaurs?

First: Statues of Icarus Blackstone and Acambalo.

If human ancestors once lived with dinosaurs, there must be relevant evidence that the image of dinosaurs would exist in ancient paintings and sculptures.

1944, a German immigrant named Wodema Zhu Slade claimed to have found prehistoric dinosaur sculptures in Acambaro, Mexico. These sculptures were made by prehistoric people. From 1944 to 1952, Wodema Zhu Slade collected more than 23,000 such sculptures, which were called "sculptures".

Dinosaur bones

The discovery of the statue of Akambalo excited scientists at that time. However, it turns out that this is a scam. Some people deliberately play jokes on scientists. Archaeologists suspected that these sculptures were fakes at that time, because they looked clean and undamaged, and didn't look like artifacts left over from prehistoric times. 1969, two scholars from the University of Pennsylvania dated these sculptures by thermoluminescence dating, and found that these sculptures were made around 1939.

If the production of the statue of Acambalo is just a joke of Mexican farmers, then the production of Icarus Blackstone is the industry of Peruvian farmers. In the 1960s, a Peruvian collected more than 10,000 pieces of Icarus Blackstone with dinosaur patterns on it. As soon as people came into contact with Icarus Blackstone, they thought it was a dinosaur pattern painted by primitive people. However, in 1973, Icarus came into being.

Second: Are dinosaurs really extinct?

If the statues of Icarus Blackstone and Acambalo are considered as fakes, scientists will be disappointed, so the research on dinosaurs in recent years may be gratifying. In a sense, dinosaurs are not really extinct, and their descendants still live around us.

Archaeopteryx is considered to be a species between dinosaurs and birds.

The extinction of dinosaurs is a masterpiece of asteroids hitting the earth. The impact of asteroids on the earth was a global event at that time, not only for dinosaurs, but also for mammals and birds. When an asteroid hits the earth, the large dinosaurs will be extinct because they can't find shelter, and those small dinosaurs will definitely find caves to escape this disaster. The largest dinosaur weighs 50 tons and is 80 meters long, while the smallest dinosaur is only as big as pigeons, chickens, ducks and geese. These small dinosaurs are similar in size to mammals and birds. Since mammals and birds can escape, so can small dinosaurs. So, people can't help asking, where did those little dinosaurs go?

In fact, the real reason for the extinction of dinosaurs is not that asteroids hit the earth. The impact of an asteroid on the earth is only the landmark event of the fifth extinction. Some scientists believe that the extinction of dinosaurs is gradual, not a one-off extinction in a short time. Mammals and birds can escape, but little dinosaurs can't escape for no reason. And with the discovery of more and more dinosaur fossils, people gradually believe that dinosaurs are warm-blooded animals, and some dinosaurs even have feathers. These new discoveries are called "dinosaur renaissance".

The real reason for the gradual extinction of dinosaurs is the change of global climate. After the earth entered the Cenozoic era (65 million years ago to 5.2 million years ago), the climate turned cold obviously. With hair and feathers, mammals and birds with constant temperature adapted to the Cenozoic climate and gradually prospered. So birds and mammals are almost all over the world. There are polar bears in the North Pole and penguins in the South Pole, and reptiles can't live in the north and south poles of the earth at all. They are mainly concentrated in.

From dinosaurs to birds

The change of global climate is often a long process. In this long process, the little dinosaur has the opportunity to adapt to the environment. At a certain point, the inheritance and variation of biology is only a small breakthrough. However, after millions of years of accumulation, these tiny features have changed enough, leading to the emergence of a new species. Today, life on earth is so colorful that penguins and crocodiles look so different. However, Ediacaran, which lived 590 million years ago, was a simple multicellular creature, and only a few hundred million years' accumulation could create a gap between penguins and crocodiles.

If dinosaurs were not completely extinct, where did they go?

Third: Who is the real dinosaur?

Dinosaurs belong to reptiles and dinosaurs in the biological world, while we humans belong to mammals and primates. The range of "order" in biology is very wide. Squirrels, rabbits, monkeys, chimpanzees and humans all belong to primates. Dinosaurs are dinosaurs, and what we call "dinosaurs" in our daily life is more extensive than real dinosaurs, that is, dinosaurs. We generally call pterosaurs, plesiosaurs, black dragon, ichthyosaurs and Panlong "dinosaurs", but they are not dinosaurs, not real dinosaurs. Our common pigeons, chickens, ducks, geese and penguins are all real dinosaurs. Why do you say that? Let's take pterosaurs as an example to analyze.

Humans catch fear birds, much like dinosaurs.

Pterosaur is not a dinosaur, but a pterosaur. Pterosaurs and dinosaurs belong to the bird-neck dragon. Many species under the bird's neck dragon look like dinosaurs in the dinosaur era. However, they are not all real dinosaurs and do not belong to dinosaurs.

There are two branches under dinosaurs, namely sauropods and ornithopods, some of which later developed into birds. Today's pigeons, chickens, ducks, geese and penguins are all their direct descendants, that is to say, pterosaurs that look like dinosaurs are not dinosaurs, but chickens are real dinosaurs. Why do birds that are direct descendants of dinosaurs look different from dinosaurs? Because there is a time interval of tens of millions of years, the character changes accumulated by these tens of millions of heredity and variation are considerable. Domestic chickens and pheasants parted ways for only 1 10,000 years, but now they look very different, while pterodactyls and dinosaurs lived in the same era, but there is not much difference.

The ancestor of birds, the restoration of feathered dinosaurs.

Birds are descendants of dinosaurs, and the fossils of intermediate species are archaeopteryx. After archaeopteryx fossils were discovered, more and more scientists firmly believed that dinosaurs were not all extinct, and some of them evolved into birds.

So dinosaurs have never left the earth and have been living around us. Chickens are descendants of dinosaurs. How many hundred million chickens are there in the world now? There are 20 billion chickens in total, and the global population is only over 7 billion, which means that the number of chickens is more than the global population. If birds are descendants of dinosaurs, then chickens are the most successful dinosaurs in evolution. They provide human beings with chicken, chicken wings and drumsticks, and the advantage is that they can prosper again on this planet with the help of human strength.

Finally, why do human children like dinosaurs?

Now, although there is no evidence that human ancestors have seen dinosaurs, scientists have found a lot of evidence that birds are descendants of dinosaurs. Humans like animals. First of all, this animal is not ugly and can be liked by human beings. As the saying goes, beauty is the key, so is eating bamboo. In human society, the treatment of giant pandas is completely different from that of bamboo rats. The reason why the giant panda is deeply loved by human beings is mainly because human beings think it is cute and beautiful, not just because the number of giant pandas is scarce. Due to the destruction of the earth's environment by human beings, there are too many animals on the earth that are rarer than giant pandas. Humans only like giant pandas, just as there are thousands of extinct animals in Qian Qian, and humans have a soft spot for dinosaurs. "Like" and "cute" can't be evaluated by scientific data at all. People will like it only if they like it, which is determined by people's subjective concept.

dinosaur

Dinosaurs are not rejected by human beings in appearance because their bodies are very similar to those of ostriches, chickens, ducks, geese and pigeons today. Living with chickens, ducks and geese for a long time, human beings naturally don't hate their ancestors, while crocodiles, lizards and snakes, which are also reptiles, don't have this kind of treatment. Humans are even very afraid of crocodiles and lizards and are very disgusted with snakes. Human children are generally. Therefore, although humans have never seen dinosaurs, they live with their descendants day and night.

Children's obsession with dinosaurs is also related to people's obsession with all kinds of strange giant monsters. Dinosaurs are similar in appearance to birds today, but larger than birds and belong to trolls. If they are just trolls, children will not be obsessed, because trolls represent terror. However, dinosaurs are extinct trolls, and these trolls can't be right. Besides, dinosaurs are extinct animals, and extinct animals can also cause children's obsession with science, which is one of the reasons why children like dinosaurs.

Because of children's obsession with dinosaurs, a large number of cartoon themes centered on dinosaurs have appeared, and dinosaur toys and sculptures can often be seen in children's amusement parks. Although dinosaurs were extinct, they lived in the world of human children.

Dinosaurs are extinct animals, and we will think that dinosaurs did not evolve successfully on the earth. However, human obsession with dinosaurs may eventually lead to the resurrection of dinosaurs. If human biotechnology is very developed, we can use the remaining DNA information on fossils to revive extinct creatures on earth. So, which one will be resurrected first? It must be a dinosaur. Just as people love an animal, it will not be extinct, but will prosper. If the extinct animal is deeply loved by human beings, it will theoretically revive and prosper again. In this way, dinosaurs were not creatures that failed in evolution, but perhaps only temporarily left the earth. Of course, if humans want to revive dinosaurs in the future, they must do some ecological analysis to revive extinct creatures. Is it suitable? Whether their resurrection is a good thing for the earth's ecology is also a very important issue to consider.
