How did dinosaurs die?
It's hard to say. In the past, scientists had two conjectures. The first is the impact theory (meteorite impact), the second is the volcano theory (the method of collective volcano on the whole earth), and finally the meteorite theory.

Every morning when I watch running in the botanical garden, I think of dinosaurs running around the Mesozoic earth. Such a prosperous species has actually become extinct. I think there are at least ten reasons for this extinction.

Reason 1: Comets hit the earth, causing dust on the earth's surface, blocking sunlight and causing a large number of plants to die. Dinosaurs couldn't find food and starved to death in large numbers until they became extinct. Almost all formal books say so. Although it has not been confirmed, people still talk about it.

The second reason: the current medical beauty technology can be younger. What boys mean is that many beautiful girls are made of plastic surgery and rouge. (Of course, girls can also ask boys: "Why are there fewer and fewer frogs now?" )

Reason 3: Do you know how dinosaurs died out? Because they will not be backed up! -The advertising words of a backup software make people feel that if they don't back up their own words, they will die miserably.

Reason 4: The dinosaur got up in the morning, opened his eyes and suddenly found that his wife was actually a dinosaur. They were frightened and vomited blood and died. Many dinosaurs were scared to death. -the fashionable language of new human beings on the Internet. I wonder if their lovers will be scared by the "dinosaurs" next to them in the future.

Reason 5: Due to the indiscriminate killing of human beings, the living environment of dinosaurs became worse and worse, and there was less and less food, so they had to prey on each other. When the last dinosaur bit his mandible, the dinosaur family died. ——%#? ? Fallacy! Try biting your nose.

Reason 6: Vegetarian dinosaurs ate a lot of plants, which made them often fart. The massive emission of carbon dioxide caused the greenhouse effect, environmental deterioration and the extinction of dinosaurs. -a well-known magazine said that some people put forward the view that it seems that human beings should also pay attention to the problem of fart.

Reason 7: Because the ice age was too slippery, the friction force was almost zero. According to Newton's first law, dinosaurs would keep moving until they hit the wall and died. -Flexible use of knowledge learned in class, application of Newton's first law to solve world problems, Mr. Newton can die laughing.

Reason 8: Dinosaurs belong to haploid animals. In order to obtain larger individuals for intraspecific struggle and interspecific competition, male dinosaurs treated the female dinosaurs who were about to give birth with colchicine. As a result, the female dinosaur took too much colchicine and died. Male individuals cannot produce new individuals and become extinct. -Only by applying what you have learned can you truly reflect the value of learning, but these male dinosaurs obviously didn't learn biology well in their sophomore year.

Reason 9: There is a credibility crisis in dinosaur society. In order to prove their innocence to others, dinosaurs looked for ways to get it. A tutor explained the chemical principle when explaining the sentence "I am not afraid of being smashed into pieces, but I want to remain innocent in the world": "I (CaCO3) generate calcium oxide, so I am innocent!" Inspired by this, dinosaurs built smelters and rushed into them to seek innocence. -The result ... The result was not "innocent", was it?

Reason 10: Dinosaurs had no active interest in life, no stable food and stable residence. The unemployment rate in dinosaur society remains high, personal safety is not guaranteed, there is no freedom of speech, public health is extremely poor, social order is chaotic (dinosaurs eat dinosaurs), young people have no education, and the elderly have no support. This group has no sense of innovation, does not know how to seek development, and is doomed to perish. -Darwin will vomit blood! This man used philosophical knowledge to explain the reasons for the extinction of dinosaurs, believing that no one has ever come before!
