More than 500 million years ago, it was the Paleozoic period called the Cambrian in the history of geology. As the first period of the Paleozoic era, this period is not only of great significance to geological research, but also the most crazy and gorgeous in the history of paleontology. Mysterious era. Before the Cambrian period, the species on the earth were relatively monotonous. During the Cambrian period, in a relatively short few million years in geology, the global species suddenly evolved wildly. Countless invertebrates, arthropods, Molluscs, brachiopods and annelids all appeared on this planet without warning, which greatly enriched the diversity of species on the earth. This bright few million years is called the Cambrian Explosion of Life. After hundreds of millions of years of evolution, the earth with colorful life forms today. The cause of the explosion of life in the Cambrian Period is a huge mystery and the biggest paradox of Darwin’s theory of evolution. If, after human civilization conquers the entire planet Today, the Cambrian is coming again, and species around the world are evolving wildly again. What kind of baptism will this planet encounter? What fate will the human beings who have fallen from the top of the food chain face?
