Learn more about a time period marked by an intense burst of evolution. 3 min read The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known.

Internal, genetic factors were also crucial. Recent research suggests that the period prior to the Cambrian explosion saw the gradual evolution of a "genetic tool kit" of genes that govern ...

Then, at the beginning of the Cambrian Period, life opened its eyes. In the 15 million years that followed the evolution of vision, most of the major animal groups we know today appeared. After ...

FROM 508 MILLION YEARS AGO TO TODAYPreserved in the Burgess Shale of British Columbia, the worm Canadia spinosa was part of an explosion in biodiversity during the Cambrian period that gave birth ...

Some of the best information about early animals comes from fossils dating back to the Cambrian period, which started around 541 million years ago. During this time, Earth experienced a burst of ...

Around 541 million years ago, at the start of the Cambrian period, hundreds of thousands of new species appeared within a span of about 20 million years — an event known as the Cambrian explosion.

Animals living about 500 million years ago spent time on mudflats that were periodically exposed to the air. The finding suggests that some of the earliest animals were able to survive outside of ...

visitors can follow fossil evidence tracing the evolution of life during the Cambrian period — the first geological period of the Paleozoic era — which lasted from 541 million to 485 million ...

the most severe biological crisis since the Cambrian period. The discovery, led by Prof. Liu Feng, from the Nanjing Institute of Geology and Paleontology (NIGPAS) of the Chinese Academy of ...

But during the Cambrian period, creatures with complex body structures emerged. Scientists who study such things call this the "Cambrian explosion" because it was a period of rapid evolution.

A fossil analysis suggests that the yunnanozoan, a wormlike fish that flourished around 520 million years ago, sported structures that were the precursors of the head and jaws of modern vertebrates. A ...
