Quiz 3: What is meant by the Cambrian explosion?
Ans. The Cambrian explosion was a period of rapid evolution that occurred around 540 million years ago, when most major animal groups first appeared in the fossil record. That was a time when a wide variety of complex life forms suddenly appeared, including arthropods with legs and compound eyes, worms with feathery gills, and predators with tooth-rimmed jaws. This explosion lasted for about 13 to 25 million years.
Researchers are still debating the exact cause of the Cambrian explosion. Markedly, some scientists believe that a small increase in oxygen levels in the atmosphere and ocean triggered the explosion. Others believe it was the result of a key evolutionary innovation, such as the development of vision. Before the Cambrian explosion, most organisms were simple, made up of individual cells or small multicellular organisms. The increase in variety of life stabilized during the Cambrian and into the following period,. Consequently, since then we have seen very few new animal classes.
