Since the birth of life on the earth, species and organisms have been competing with each other, and the struggle between species and nature has been constantly interpreted. Those who can adapt to nature are chosen to survive, and those who cannot adapt are eliminated. Only by constantly evolving and adapting to its own living environment can organisms continue to survive.
Dinosaurs, as the representative of Mesozoic, once dominated the biological species of the earth for a long time. But according to geological research, there are quite a few kinds of dinosaurs, with different shapes and habits. The largest fragile double-chambered dragon may be more than 50 meters, while the smallest hummingbird may be less than 10 cm. As far as eating habits are concerned, there are docile herbivores and fierce carnivores, as well as omnivorous dinosaurs who are both vegetarian and vegetarian; In terms of living space or geographical distribution, some fly in the sky, some crawl on the ground and some swim in the water. In this way, dinosaurs were not so much the main species on the earth at that time, but rather the collective name of all species at that time.
Due to the long geological evolution process, the earth constantly absorbs meteorites, interstellar dust and other substances, which makes the earth expand in volume and increase in gravity. The survival pressure of dinosaur population is increasing, especially those large groups can't bear its huge size, so they have to make choices and gradually evolve in lifestyle and individual characteristics. Some parts in the sky evolved into crows and other groups, while some parts on the ground went too far into the water like crocodiles, and their bodies shrank like lizards, leaving the large undeformed groups out.
As a special life on earth, man has also experienced several evolutionary processes, but his choice is more flexible and thorough than that of dinosaurs. But in the end, there was polarization. Some of them evolved into humans, and some chose forests to become apes. Generally speaking, the jungle law of "natural selection for survival of the fittest" is the inevitable result of the evolution of all living things.
Dinosaurs are eggs, humans are viviparous, and human babies need a lot of time to raise.
As we all know, like snake BB, it will hunt when it is born; Mammals BB can be independent after one or two years; As far as human babies are concerned, it is the most useless, and nothing will cause trouble. If they are sensible, they must be raised for two or three years first, and then spend more than ten years learning knowledge and being independent.
It is the backward reproduction mode of human babies that accumulates and inherits the knowledge of predecessors from generation to generation, accelerates the knowledge reserve of future generations, and causes the change from quantitative to qualitative, thus moving towards civilization. For example, if the previous generation developed Pythagorean theorem, then the next generation can learn and apply it directly, and then develop a new theorem on Pythagorean theorem without repeated research.
Egg-laying animals have a problem: the last generation gives birth to the next generation, and they basically don't care, but birds still care, and they don't care whether they fly or not, and they can't talk about educating the next generation.
Even if the dinosaur suddenly had a whimsy, it even invented something. The next generation is born, and the next generation doesn't know, so the inheritance or accumulation of knowledge is broken. Even if the next generation is smarter than the dragon, the same whimsy and inventions will take the same amount of time and cannot be developed at all. For example, dinosaur dad developed Pythagorean theorem, but he couldn't tell dinosaur BB, because he couldn't find dinosaur BB, or he ate it when he saw it. Dinosaur BB will take the time to re-study Pythagorean theorem.
Everything has to start from scratch, not to mention 80 million years, and 800 million years will not form civilization.
The early earth contained a lot of oxygen, which was very suitable for large creatures like dinosaurs to thrive. With the change of climate, dinosaurs and their food could not adapt to the environment well, so they eventually became extinct. After millions of years of evolution, some branches of dinosaurs have had high IQs, such as raptors and odontosaurus, but the rapid changes in the environment have not given them opportunities.
Humans are different. First of all, human beings are herbivores, and there are many kinds of recipes and tools, which makes human beings not only have a good ability to adapt to the environment, but also have a certain ability to change the environment. Therefore, human ancestors can learn and develop step by step from trees to the ground, from caves to plains, from hunting to reproduction, and pass this knowledge on to the next generation through socialized activities.
The reason why human beings can evolve into higher life. The most fundamental thing is that people have the ability to work. Labor can not only actively transform the world to meet human needs, but also promote the development of human brain to advanced intelligence. The establishment of advanced civilization by human beings cannot be separated from a pair of working hands.
