Microbial life on Earth still holds surprises. A recent study overturns our certainties about the emergence of oxygen ...

Nearly three-fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese ...

One thing geology teaches us about is the existence of another monumental event in the history of Earth, 2.4 billion years ...

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

So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

Bacteria used oxygen far earlier than expected, reshaping views on early life, evolution, and photosynthesis origins.

The recent paper's case for green oceans in the Archaean eon starts with an observation: waters around the Japanese volcanic ...

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 ...

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.

But a new study, published today in the journal Science, maps out the evolution of ... the development of oxygenic (oxygen-generating) photosynthesis in cyanobacteria and carbon deposition, ...

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

Nothing in biology makes sense except in the light of evolution ... of years, oxygen in the atmosphere slowly accumulated. Before this “Great Oxidation Event”, Earth contained almost no ...
