Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights into the evolution of the distinct upright postures ...

Learn how oxygen’s early rise could have given complex life the energy boost it needed to evolve.

A new study explains how climbing down trees helped shape upright posture in early primates and changed the course of evolution.

Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key ...

During photosynthesis, trees convert the carbon dioxide to sugars and in doing so produce oxygen as a biproduct, which is vital for life on Earth. “Trees draw carbon dioxide out of the atmosphere and ...

This football-sized creature could grind its teeth like a hard-core plant-eater, back before that was really a thing — and it may be the earliest vertebrate herbivore ever found.

Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights ...

The evolution of human hands is one of the most important – and overlooked – stories of our origin. Now, new fossil evidence ...
