Is the origin of life on Earth from dinosaurs to humans?

No.. It's a marine creature ... The ocean first covered the entire continent in the hope of that.

The formation of all species on the earth is staged, or the result of natural selection and natural evolution, and it also revolves around the rules of natural selection. In different eras, biological species will be born randomly and will be eliminated randomly, which is the inevitable law of survival of the fittest. At that time, dinosaurs, including human beings now, actually appeared in stages, and it was also a kind of natural selection and natural evolution given by the earth to organisms.

After the extinction of the dinosaurs, mammals began to develop, and then primates appeared, about 5 million to 6 million years ago, Australopithecus tried to come from the tree to the tree because of environmental changes, if the environment does not change, Australopithecus may have to delay the time to get off the tree, this delay does not matter, the subsequent things will have to change.

Human beings are special because they have intelligence, and they seem to be incompatible with other creatures on the earth, which is not the case, and human beings are just creatures on the earth, because of the increase in brain capacity, because they have learned to use tools, language, and cooperation, and gradually have high intelligence, which is not achieved overnight, it is gradual, it is logical, it is in line with the trend of life evolution, and there is no particularity.

Because there is a good change in the era of dinosaurs, and then there is a large space for dinosaurs to live in, and only through mutation can humans be slowly converted.

After the extinction of the dinosaurs, mammals began to develop, and later primates appeared. About 10,000 to 10,000 years ago, Australopithecus tried to move from one tree to another due to environmental changes. The ape can delay the time of getting off the tree, and the delay does not matter, the follow-up.

At that time, it was necessary to have such an experience before we could evolve human beings, and only then did we conform to the laws of evolution, and it was also very common-sense.

Dinosaurs lived on Earth for about 100 million years and were a representative and iconic species of the Mesozoic Era.

Dinosaurs only appeared in the middle of the Triassic period, about 100 million years ago. After the Jurassic and Cretaceous periods of the Mesozoic Era, it did not become extinct until 65 million years ago. Lived together on Earth for 165 million years.

The Mesozoic Era began in the Triassic period about 100 million years ago and ended at the end of the Cretaceous period 65 million years ago. But in the early Triassic period of the Mesozoic Era, there were only primitive reptiles, and dinosaurs had not yet appeared.

The Earth has been born for 4.6 billion years, and in these 4.6 billion years, the Earth has experienced five mass extinctions, the most recent of which was the extinction of the dinosaurs 65 million years ago. Then it took countless more years for the birth of humanity.

It took about 3 million years for human beings to evolve from primitive life to intelligent life, which is too short for the evolution of a life, and it has to be said that human beings have created a miracle of life.

Dinosaurs were the overlords of the earth 65 million years ago, it relied on a huge and robust physique to stand at the top of the food chain, and dinosaurs lived on the earth for hundreds of millions of years, such a long time, did not dinosaurs evolve into intelligent life, did not develop into civilization? I'm afraid no one can do this question.

Dinosaurs lived on the earth for about 100 million years.

Dinosaurs refer to the nearest common ancestor of Triceratops, modern birds, and Diplodocus and all of their descendants. To facilitate research, dinosaurs can be divided into avian and non-avian dinosaurs. Among them, non-avian dinosaurs lived only in the Mesozoic era (Triassic, Jurassic and Cretaceous) and were all extinct 65 million years ago.

The muscular limbs, long tails, and massive bodies are some of the non-avian dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains). During the long age of dinosaurs, there were various kinds of dinosaurs.

The dinosaur species of each era are different and have a strong imprint of the times. The Triassic was an early stage in the evolution of dinosaurs, with the emergence of major clades of dinosaurs including sauropods, theropods, and ornithischians, with the most famous representatives including Plateosaurus, which belonged to the protosauropods.

Habits

The plants that grass-round digging dinosaurs could eat were limited by their height, so some small herbivorous dinosaurs would stand on their hind legs in order to eat the leaves of plants in high places. Carnivorous dinosaurs fed on herbivorous dinosaurs and other animals. The different foraging patterns of various dinosaurs are also reflected in their teeth.

Sharp teeth and claws were preyed upon by carnivorous dinosaurs. Tyrannosaurus dinosaurs often went it alone because they sought out lone herbivorous dinosaurs. Some dinosaurs would move in groups, locking on to their prey and swarming and slicing open the prey's abdomen with the second finger of their claws.

Herbivorous dinosaurs generally had some special "Orange Blade" to deal with the attacks of carnivorous dinosaurs, which were sometimes tough leather armor, bone clubs, or bone spikes, and sometimes powerful tails. Such as mallet dragon and so on. Large herbivorous dinosaurs would act in groups, and when threatened, they would collectively hold their ground and fight back.
