Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely ...

The Great Oxidation Event (GOE) some 2.4 billion years ago established the oxygen-rich atmosphere that many living things ...

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.

Scientists assumed most forms of life before the Great Oxidation Event didn't metabolize oxygen—but recent research suggests ...

Discover the evolution of bacteria through machine learning, DNA comparisons, and the Great Oxidation Event 2.4 billion years ...

A conceptual rendering suggests how Earth's land elevations and oceans may have appeared during the assembly of Kenorland, left, and later, right, after the Great Oxygenation Event. A University ...

Bacteria may have adapted to oxygen well before Earth’s atmosphere was saturated with it, according to a new study. Researchers who traced microbial evolution over billions of years – using machine ...

This explosion of microorganisms is known as the Great Oxygenation Event (GOE) and took place around 2.5 billion years ago. The microorganisms’ ability to successfully multiply depended on a lack of ...

So what changed, and how did it happen? The scientific consensus is that about 2.5 billion years ago, the Great Oxygenation Event (GOE) took place, most likely due to a proliferation of ...

University of Queensland scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some ...
