If the dinosaurs had not become extinct 6,500 years ago, would humans still exist?

If the dinosaurs had not become extinct, humans would not exist. If the dinosaurs were not extinct, then huge dinosaurs would rule the earth, the lives of human ancestors would be threatened, and their evolution would be hindered. At that time, not only humans, but also other mammals would not be able to have many achievements. With great evolution, mammals will eventually become extinct in this world.

As for the extinction of the dinosaurs 65 million years ago, many scientific research teams Zhu Yong currently believe that it was the asteroid impact theory. They believe that the impact of the asteroid caused many volcanic eruptions in the earth's mountains, leading to global climate warming. It has led to the extinction of many living things on the earth. But on the other hand, this disaster also brought about a turn for the better for other creatures. Before the extinction of the dinosaurs, the oxygen content on the earth was very high, and many animals developed towards huge sizes, which posed a threat to other smaller animals. Just like the ancestors of humans, they had to be on guard at all times. Dinosaur.

After the volcano erupted 65 million years ago, the oxygen content on the earth gradually decreased, the climate warmed, the earth was wrapped in a lot of organic matter, dinosaurs and other large animals gradually became extinct, and humans had more There are many opportunities for evolutionary development, so if the dinosaurs had not been extinct, humans would not have existed.

If dinosaurs had not become extinct, they would have replaced mammals like humans, and the overall structure and vegetation of life on Earth would have been different from what it is now. Some researchers once hypothesized that during the Mesozoic era, giant sauropods on the earth prevented the growth of forests and the formation of tropical rainforests. Likewise the presence of dinosaurs prevented the evolutionary development of mammals. Many people think that the extinction of the dinosaurs 65 million years ago was a disaster, but for researchers who know the truth, it is a great blessing, because that disaster made humans what they are today. Without the extinction of the dinosaurs, humans would not be the same. There will be no way to evolve, and humans will not be able to survive and develop.
