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

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

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

Bacteria and archaea contain only single-celled organisms. Previous chemical analysis of Prototaxites fossils indicated that ...

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 at the University of Queensland have contributed to the development of a precise timeline for bacterial evolution, indicating that some bacteria used oxygen long before they evolved the ...

Researchers have used machine learning, genomic data, fossils and the Earth’s geochemical history to create a timeline of ...
