The Cambrian Explosion was a dramatic burst of evolutionary changes in life on Earth. During the Cambrian Period, which began about 540 million years, trilobites were the dominant species.

The Cambrian Explosion: A Burst of Life The Cambrian Explosion, which occurred around 541 million years ago, marked a significant period in Earth’s history.

Walcott’s discovery was further evidence of the so-called Cambrian Explosion — the apparently abrupt appearance of complex animals in the fossil record within the Cambrian Period, from about ...

The early Cambrian period brought a rapid expansion of new life-forms as animals adapted to new habitats, food sources, predators and prey.

The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. The Cambrian Explosion saw an incredible diversity of life emerge, including many major ...

melted and oxygen reached a critical threshold that allowed more complex multicellular life to flourish. In the Cambrian period, animal life as we know it exploded into its myriad forms.

The earlier Cambrian period witnessed the origins of animals but by the end of the Ordovician period, Earth was home to more varied and diverse ecosystems.

A groundbreaking study suggests that the famous Cambrian explosion—the dramatic burst of diverse animal life—might have actually started millions of years earlier than we thought. By analyzing ancient ...

Most experts believe complex life on Earth can be traced back roughly 635-to-800 million years ago to the Cambrian Period—but some researchers say they now possess evidence that dramatically ...
