Salt is an essential nutrient for the human body. But hundreds of millions of years before the first humans, salt minerals ...

Much of our understanding of Precambrian (0.542–4 Gyr ago) environments is limited to inferences gained from geological proxies. However, the inherent property of evolution in biological systems ...

The strange creatures that lived in the Garden of the Ediacaran more than 540 million years ago, before animals came on the scene, may have been much more dynamic than experts have thought. The Garden ...

A number of Vendian (latest Precambrian) body fossils have traditionally been considered arthropods or arthropodlike organisms. Several Cambrian "weird wonders" have also been linked with the ...
