Earth's first bacteria used oxygen about one billion years earlier than we thought
Bacteria used oxygen far earlier than expected, reshaping views on early life, evolution, and photosynthesis origins.
Molecular clock analysis shows bacteria used oxygen long before widespread photosynthesis
Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely ...
Earth’s oceans weren’t always blue, scientists say
But while lifeless during that time, the planet was already covered by vast oceans dotted with hydrothermal vent systems that ...

Oxygen metabolism in bacteria arose before Earth’s Great Oxidation Event
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 ...
Ancient Bacteria Were Breathing Long Before Oxygen Became Abundant
Scientists assumed most forms of life before the Great Oxidation Event didn't metabolize oxygen—but recent research suggests ...
