Researchers found that cooperative fluid dynamics between single-celled organisms may have driven the evolution of ...

Tajika and his team used a numerical model to simulate key aspects of biological, geological and chemical changes during the late Archean eon (3.0–2.5 billion years ago) of Earth's geologic history.

But while lifeless during that time, the planet was already covered by vast oceans dotted with hydrothermal vent systems that ...

At 2.5 billion years old and weighing in at 2.5 tonnes, the banded iron formation is so heavy that Museum engineers had to reinforce the floor underneath it in Hintze Hall. 'The rock tells a ...

From about 4.5 to 2.5 billion years ago, the Sun was far fainter than today ... This problem of why the Earth was not heavily glaciated despite weak solar radiation has become known as the ...

Perhaps the most compelling reason to understand “deep-time” climate change is in how it relates to the origin and evolution of life on Earth ... 3.9 to 2.5 billion years ago (Bya) (Figure ...

About 4.5 billion years ago, gravity coaxed Earth to form from the gaseous, dusty disk that surrounded our young sun. Over time, Earth's interior—which is made mostly of silicate rocks and ...

Tajika and his team used a numerical model to simulate key aspects of biological, geological and chemical changes during the late Archean eon (3.0-2.5 billion years ago) of Earth's geologic history.

the 3.5 billion-year-old crater may help revise our understanding of some of the planet’s earliest eras, as well as the history of life on Earth. The Archean Eon (4–2.5 million years ago) is ...
