The sudden appearance of complex life forms in the fossil record is called the Cambrian Explosion. It refers to a relatively short period in Earth's history, around 540 million years ago, when there was a rapid diversification and emergence of diverse animal species. The Cambrian Explosion marks a significant milestone in the evolution of complex life on our planet.
The Cambrian Period is divided into three eras: the Early Cambrian, Middle Cambrian, and Late Cambrian. These eras refer to different stages or time intervals within the Cambrian Period, which lasted from about 541 to 485 million years ago. Each era is characterized by different geological and biological events, including the diversification of early animal life.

Cambrian period
Referred to as the "Cambrian explosion", most major animal groups first appeared in the fossil record beginning about 530 million years ago.
The Cambrian era saw the rapid evolution and diversification of many animal phyla, known as the Cambrian Explosion. This era, approximately 541 to 485 million years ago, was a pivotal time in the evolution of life on Earth, leading to the emergence of a wide variety of body plans and organisms.
Find some fully formed elephant fossils in Cambrian rock. Find ANY modern animal before it's evolutionary ancestors in the geologic column. Evolution would be unable to explain this.AnswerGOOD LUCK
Any time you see an animal. The Cambrian explosion was when the different kinds of animals developed - all the different animal phylums. So if you see an insect on a mammal you see the Cambrian explosion.

The sudden appearance of most of the major animal phyla within the fossils early in the Cambrian period. This caused a sudden diversification of life.
