Several times in the past 541 years, many, or even most, of the species on Earth became extinct in a geologically short time.

What is species?

A species is both a unit of biodiversity and an organism's basic taxonomic classification in biology. They belong to a group of related creatures that can breed with one another and have similar traits.

The Paleozoic Era, is a significant period of geologic time that lasted from approximately 252 million years ago until 541 million years ago when the end-Permian extinction, the biggest extinction event in Earth's history, occurred. It was marked by an extraordinary diversification of marine life during the Cambrian explosion.

Therefore, 541 years ago, many, or even most, of the species on Earth became extinct in a geologically short time.
