Dinosaurs are almost fabulous creatures for modern humans. They cannot be seen with their own eyes, their traces have long been covered with a large layer of soil, but still they still remind us of their existence. Through the traces that they left behind. How did the dinosaurs come about? Let's talk about it.
How dinosaurs were born
We will not describe in detail all the steps of evolution. This is a very long and voluminous topic. Many scientists claim, based on these studies, that these creatures appeared about a hundred - two hundred and twenty-five years ago. Presumably, dinosaurs are descended from reptiles, like all mammals (and not only) on earth. That is, out of the water.
At first they were small, about the size of a large turkey, but soon began to play the role of natural selection. Individuals that had the opportunity to move on four legs survived. So it was easier to be important for large animals. Therefore, they began to grow in size.Of course, it has been for many millennia. And it came to the fact that some dinosaurs became the size of a high-rise building, approximately twenty-four meters in height and weighing more than thirty tons. These animals could get food from the treetops, but at the same time it became difficult for them to move and they began to live in the marshes and not move for long distances.
Also, on a par with herbivorous species, there were also carnivorous species. These animals did not reach such enormous sizes as herbivorous representatives of dinosaurs, but were very mobile. But the first and second touched climate change on Earth. And their comfort zone is shaken and they, dinosaurs, began to die out. So where did dinosaurs come from? There is no exact answer, there are only speculations of scientists and archaeologists. But their origin is considered the Mesozoic era.
