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 also called the?
age of invertebrates
Why did the Cambrian explosion may not have been an explosion?
The Cambrian Explosion wasn't a literal explosion. Instead, it was a span of time when organisms evolved into an immense number of new forms, and biodiversity increased greatly, reaching its modern level. The Cambrian Explosion occurred between 530 and 450 million years ago.

What does the term Cambrian Explosion mean?
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.

The group of animalia (animals) did not fully form until the Cambrian period. There is evidence of simple life (single-celled) and small multi-celled life forms from before the Cambrian explosion.
