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

Scientists at Goethe University uncover how the oldest enzyme in cellular respiration functions – opening the door to ...

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

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

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.

Nevertheless, studies of ancient bacteria that still occur today in ecosystems without oxygen, e.g. in hot springs at the bottom of the ocean, suggest that a special form of respiration could have ...

This method created a more lucid chronology of the evolution of bacteria throughout Earth's history. With analysis of ancient bacterial genomes, the model predicted earlier oxygen use. Life's deep ...
