Fossils offer a glimpse into Earth's ancient life, revealing the origins and evolution of complex organisms. Discoveries like ...

Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found.

As Ediacaran organisms became more specialized, some species couldn’t keep up with their neighbors, the team reported on May 17 in the journal PLoS Biology.

Sorting out the way these 570- to 540-million-year-old, enigmatic creatures ate supports the argument that they behaved like more modern-looking animals and evolved into shapes that helped them feed.

The Ediacaran period ended around 540 million years ago, just before the Cambrian period, which saw a massive explosion in marine animal life.

During the Ediacaran — a period named for South Australia's fossil-rich Ediacara Hills — animals weren't the major players. "There are some animals there, but they're not dominating the system ...

DURING the Cambrian period, which began 541m years ago, animal life took a remarkable leap forward. The first creatures believed by most (though not all) palaeontologists to be multicellular ...

Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found.

University of Rochester researchers studied Earth’s magnetic field during the transformative Ediacaran Period, which spanned from about 635 to 541 million years ago. The research raises ...
