with the eventual appearance of the lineages of almost all animals living today. This stunning and unique evolutionary flowering is termed the "Cambrian explosion," taking the name of the ...

This daily feast-and-famine cycle in oxygen availability created an intense physiological challenge for early animals, forcing them to develop adaptations to handle fluctuations in nutrients. For ...

The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today. Among them were the chordates, to which vertebrates (animals with backbones ...

In a quiet part of what is now South Australia, more than half a billion years ago, life was locked in battle. The ocean ...

Worminess wasn’t the only factor that brought oblivion to the Ediacarans and triggered the Cambrian explosion—there also were changes in ocean chemistry that allowed animals to acquire hard ...

Focused on Cambrian fossils, the study reanimates a species long trapped in the pages of forgotten paleontology.

The evolution of the eye is likely to have been a catalyst for the explosion, initiating an arms race between organisms that were increasingly aware of their surroundings. Now, with access to uniquely ...

The control system that may have emerged at the Cambrian explosion is known as HIF-1α (hypoxia-inducible factor 1). In modern animals, this system helps cells detect and adapt to changes in ...
