Contrasting Theories on the Extinction of Dinosaurs

That is why I killed the dinosaurs. Without scientific background education it is difficult for the public to understand these problems and they rely on knowledge of scientists in this field. Despite much research on this subject, no one has given a certain answer. We read countless articles and have our own opinion on mass extinction. One theory is that changes in the solar system can lead to massive destruction.

The theory of dinosaur extinction develops mainly on the extinction of dinosaurs. According to a theory, at the end of the dinosaur era, the environmental change associated with the progressive withdrawal of the shallow ocean of the continent brought the dinosaur out of extinction. Supporters of the theory suggest that the number and type of dinosaurs will gradually decrease after millions of years.

Most scientists agree with many theories about the end of dinosaurs. The most popular theory is that asteroids end dinosaur domination. Another theory is that massive climate change in the prehistoric atmosphere caused all dinosaurs to die. - ...... Many animals think they will die because they do not have food and so much to survive. In the last paragraph I said that not all animals are dead.

The extinction of the dinosaur has become an endless argument. Scientists have discussed the causes and theories of the way dinosaurs go out for many years. Some of the reasons the dinosaurs were extinct are that they died with the impact of meteorites, small mammals ate eggs, and the floods around the world destroyed them. They can not cope with their environment, they may have slid the disc. For the problem at least 55 theories were proposed and abandoned. Whenever a scientist comes up with a theory, he must be able to prove or explain how it happened. The theories applicable to large animals generally do not apply to small animals or marine organisms. Scientists agree that everything that happens to the dinosaur will inevitably affect the whole world. If the birth rate does not catch up with the mortality rate, we will be extinct. Paleontologists divide extinction into two categories: background extinction and massive expansion
