Why did dinosaurs dominate for 160 million years without producing wisdom, while human beings did it for millions of years?

The earth was born 4.6 billion years ago, and then it was very lucky to be a planet of life. The earliest life on earth was born about 3.8 billion years ago. After continuous development and evolution, simple life has been changing to complex life, and gradually there is a life world rich in species.

In fact, the whole life evolution history of the earth is not smooth. The life history of billions of years has gone through five mass extinctions, four of which were caused by the violent ecological occurrence of the earth, and only the last one was caused by the impact of an asteroid. I believe many friends know that the dinosaur mass extinction event 65 million years ago, an asteroid, ended the era when dinosaurs dominated the earth for 160 million years.

After the extinction of dinosaurs, after a long time, human beings were born, and it took only millions of years for human beings to evolve into intelligent life. Some people may think that millions of years is not short, but in fact, in the history of life evolution, especially in the history of intelligent life, millions of years of time is incredible. You know, dinosaurs have dominated the earth for 160 million years without producing wisdom.

So someone asked this question: Why did dinosaurs dominate the earth for 160 million years without producing wisdom, while human beings did it only for millions of years? To solve this mystery, we need to start with natural selection, the survival of the fittest. Although it is difficult to trace the origin of life, we know that the birth of life is determined by nature.

What kind of life is born on the earth, and what kind of evolutionary direction is chosen is determined by nature, and the most basic law of nature is natural selection, survival of the fittest. Dinosaurs appeared in the Late Triassic 240 million years ago. They originated from the primitive species of ornithoceles, and the early species were very small. Dinosaurs’ dominance in the Jurassic and Cretaceous was synchronized with their large-scale development.

The road of dinosaur’s enlargement was also the result of natural selection, which was determined by the ecological environment and other aspects at that time. One of the important elements is that the oxygen content in the atmosphere at that time was much higher than that at present. I believe many friends know that there was a giant insect era in the life history of the earth, which was called the Carboniferous period, about 350 million years ago. The Carboniferous is also known as the giant insect age, which was dominated by insects, and a large number of giant arthropods were born. At that time, a kind of millipede called Jiexiong was up to 2.4 meters long. The wing span of dragonflies was 74 cm, and that of scorpions was 70 cm.

The Carboniferous period, 359-299 million years ago, lasted about 60 million years. During this period, the atmospheric oxygen content was very high, the climate was warm and humid, and there were large tropical rain forests and swamps. It is this special ecosystem that created the birth of the giant insect era. The age of dinosaurs actually emerged after the Carboniferous mass extinction.

The ecological climate of the Late Triassic is very similar to that of the Carboniferous, with high oxygen content, humid and warm climate and relatively high temperature. This special climate was specially created for the creation of large organisms. A large number of giant insects were born in Carboniferous, and large dinosaurs were created in the Late Triassic. This is the result of natural selection. Why didn’t the dinosaurs give birth to wisdom in their 160 million years of dominating the earth?

In fact, the main reason is that wisdom plays a very small role in the evolution of natural life. There are many ways of life evolution. No matter which way, the ultimate goal is to become a powerful creature and be able to stand at the top of the food chain. Which is easier to achieve this goal in terms of strong and tall physique and intelligent choice?

Maybe many people say that with super intelligence, we can become a powerful creature and the overlord at the top of the food chain. Is that true? Of course not. In fact, it’s easier for dinosaurs to stand at the top of the food chain when they choose to be physically strong. When dinosaurs rely on tall and strong physique to become the overlord of the earth and stand at the top of the food chain, do they still need wisdom? Of course not.

No matter what kind of life, the purpose after its birth is to survive, to be able to rely on a strong body to dominate, why choose to rely on wisdom? I believe many people have heard such a saying: any conspiracy in the face of powerful power is smoke. A zoologist once observed a vivid example of a silver backed gorilla being chased and killed by a leopard. Although the gorilla weighed three times as much as the leopard and was much smarter, he once stabbed the leopard with a stick, but he had to escape in the face of the leopard. This fully proves that intelligence is often useless in the process of animal predation and fighting.

Intelligence is not very useful for the survival of nature. For dinosaurs, their strong body is the most powerful strength. If modern humans don’t use modern weapons and fight with dinosaurs with their bare hands, I’m afraid hundreds of people are unlikely to defeat a strong dinosaur. It can be seen that in nature, physical strength is more useful, more practical and easier to survive than intelligence.

Since intelligence doesn’t play a very important role in the nature of biological evolution, why did our ancestors choose the evolution of wisdom, and it took only millions of years to complete the evolution of wisdom, and gradually developed into the developed human civilization? In fact, human ancestors chose to evolve to wisdom because of the cruel laws of nature.

Humans and living apes shared a common ancestor 20 million years ago, and separated from chimpanzees only 7 million years ago. More than four million years ago, Australopithecus took the first step from ape to human. At that time, apes were absolutely at the low end of the biological chain in nature. In addition to having flexible body methods to avoid in trees, their physical strength was relatively weak.

https://recordunknown.com/wp-content/uploads/2021/03/f0b26a5c-a9ac-47f0-ade1-9ffaf70af0e4_3.jpegAlt

At that time, there were too many animals in the animal kingdom that could threaten apes. It can be said that apes at that time could not be defeated except for small animals such as rabbits. On the contrary, they were often eaten by other large animals. At this time, due to the degradation of forests and the expansion of the tropical grassland, the ancestors of mankind had to develop to the grassland in order to survive.

However, when we arrived at the grassland, we found that the only advantage of apes in climbing trees was no longer available. There were no trees in the grassland to avoid the predation of other animals. In order to survive, our ancestors began to use their brains to think about how to avoid predators, how to catch bigger or faster prey, and how to find and develop new food resources. In this way, natural selection finally works in the direction of wisdom.

With the increasing use of brain by human ancestors, the development of brain is also accelerating and becoming more and more intelligent. The survival ability is also stronger and stronger, and gradually has a firm foothold in the grassland. When human beings have the initial wisdom and live together in groups, they will naturally have mutual communication. This is the beginning of civilization.

And humans are mammals. Mammals are the most perfect and cutting-edge works of animal evolution on earth. They have excellent thermostatic biological characteristics, high basal metabolic rate, can support more, and are easier to accelerate the development and evolution of the brain. Mammalian body structure and function are very perfect, especially the development of nervous system is very important for the evolution of intelligence. The human ancestors belong to the ape, which is the most intelligent mammal.

The second is about reproduction. Human ancestors belong to mammals. They breed in viviparous and lactating ways and care for their offspring for a long time. They live in groups and their close relatives live in the same community. In this way, the experience acquired by the predecessors can be passed on to the future generations, and it is also beneficial for the members of the group to pass on experience to each other. The reason why human beings are so smart now is largely due to education.

There is another factor that human beings can give birth to wisdom in just a few million years, and that is luck. Many people may say that the birth of human wisdom has something to do with luck? Among them, we should start with the chromosome variation of human ancestors. As a matter of fact, the evolution and evolution of human ancestors were at risk of extinction for many times, one of which occurred one million years ago, when the number of human beings dropped to only 40 individuals.

In addition to the changes in the natural ecological environment, there is also an important factor for the extinction of human ancestors, which is consanguineous marriage. It’s very dangerous to marry close relatives, especially for an intelligent species. Just when the human ancestors were facing the risk of extinction, the genetic level of human population had a decisive mutation. The original chromosome 12 and 13 fused into the present chromosome 2. This mutation spread in the population due to intimate marriage, and replaced the original genotype through genetic drift, so that humans have 23 pairs of chromosomes, while other apes still have 24 pairs of chromosomes to this day.

This mutation is of great significance to the evolution of human beings. Since then, human beings have completely parted ways with apes and made great strides towards the road of high intelligence. Without this mutation, our ancestors and prehistoric apes would not be able to completely reproduce and isolate, and several intermarriages with stupid apes would have wasted decades or even hundreds of years of evolution of our ancestors.

Thus, it can be seen that human beings have been able to complete the evolution of wisdom in only millions of years. In addition to the result of natural selection, there is also a little bit of luck. We should know that in the billions of years of life evolution history of the earth, there may be more than one kind of creatures evolving towards wisdom, but those lives are not so lucky, and finally died out on the road of wisdom evolution.

Although dinosaurs haven’t given birth to wisdom in 160 million years, they have been dominating for a long time. If it wasn’t for the fifth mass extinction event caused by the asteroid impact on the Earth 65 million years ago, it might have given dinosaurs another period of evolution, and the birth of wisdom is also possible. If so, it is difficult to say whether human beings can become the new overlord of the earth, even if wisdom was born later. You know, one mountain can’t accommodate two tigers, and one planet can’t accommodate two intelligent species. Maybe there will be a battle between human and dinosaurs.
