Life on Earth began to flourish about 3 billion years ago, possibly when primitive forms developed efficient ways to harness energy from the Sun’s light.

Researchers in Britain and Australia have discovered evidence that parts of the open ocean may have experienced a catastrophic global freeze some 700 million years ago, which nearly wiped out life on Earth.

How do we begin to understand what early life was like on Earth about 700 million years ago as our planet shifted from an oxygen-free and probably ice-covered realm to the oxygen-rich world that we know today?

Paleontologists from the University of Extremadura have discovered a new species, Cloudina carinata, the fossil of which has preserved its tridimensional shape.

A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet.
