This study presents the first physical evidence that Snowball Earth reached the heart of continents at the equator.' ...

The history of life on Earth extends far beyond the dinosaurs and ancient mammals that usually come to mind when we think of fossils. Believe it or not, scientists have actually found signs of ...

As Earth cools, a crust forms over it. Mounded bacterial formations called stromatolites appear in shallow waters of the early oceans, and small land blocks collide with one another to produce the ...

Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, ...

At 2.1 Gya there was ongoing substantial asteroidal delivery, including hemoglycin, to Earth where water was present as tidal pools or early oceans, conditions that support stromatolite formation.

Researchers hope the "exquisitely preserved" fossil will cast new light on an enduring mystery in paleontology.

A gigantic space rock that slammed into Earth more than three billion years ago grievously wounded the biosphere—and then helped it heal ...

There are only a few locations on Earth where the organisms that contributed to the development of complex life still exist. Lee Stocking Island is one of them. The organisms are stromatolites.

The wheel was likely invented around 6,000 years ago, but a new analysis of curious rocks from Israel suggests that ...

If liquid water and elevated crust existed so early in Earth’s history, was life present as well? There is carbon isotope evidence for life in the world’s oldest known volcanic-sedimentary ...

In a discovery that may further our understanding of the early evolution of life on Earth, a research team, including ...
