The Cambrian explosion was an extraordinary phenomenon in the evolution of life on the planet that led to the emergence of ...

Lather, rinse, repeat. And it all started – at least, for complex life as we think of it today – with the Cambrian explosion. It was during this period, around 530 million years ago, that basically ...

A new study of ancient fossil trails pushes the origins of complex life deeper into Earth’s history, before the Cambrian Period began.

Cambrian animals would have needed more oxygen than early sponges, concedes Canfield. “But you don't need an increase in oxygen across the Ediacaran/Cambrian boundary,” he says; ...

When the Cambrian fauna eventually arrived, Wood thinks it appeared in two pulses. The mollusks, for example, evolved just before the explosion, ...

The Cambrian Explosion was unique, Marshall said, because, though there have been mass extinctions — such as that of the dinosaurs — and recoveries since, there has never been another event as ...

A spiky worm with legs like noodles. A giant predator that looks like a cross between a walrus and a housefly. Many animals that evolved during the Cambrian period, 541 million to 485 million ...

Cambrian animals would have needed more oxygen than early sponges, concedes Canfield. “But you don't need an increase in oxygen across the Ediacaran/Cambrian boundary,” he says; ...

And critically, these innovations were all present well before the Cambrian, putting in place the raw ingredients for the explosion of forms that would eventually come about. Nature , 2019. DOI ...

The animals lived on the muddy seafloor at least 330 feet (100 meters) below the surface. "The seafloor near which the animals lived would have been teeming with bottom life," Van Roy said.

This Cambrian period critter is now considered a part of a specific group of arthropods called the mandibulates, who went on to become some of the most successful animals on our planet in and out ...
