The bacteria-first theory, also known as the reductive hypothesis, picked up support in 2003 when French researchers discovered a giant virus in the sludge of a water tower in Bradford, England.

Phosphine, a simple molecule consisting of three hydrogen atoms and one phosphorus atom, is thought to be created by anaerobic bacteria on Earth. Thus, it can be detected emanating from sewers and ...

Experiments performed on the International Space Station have suggested that bacteria from Earth could be used to extract useful minerals on the moon or Mars.

Although these nanotubes were first observed only in 2011, biologists now think that bacteria have been making these structures all along unnoticed. Photographs: Left: Sci. Adv. 10, eadj1539 (2024 ...

For anaerobic bacteria, there are sets of reactions they do perform, including turning other compounds into things like phosphine. They turn carbon dioxide into methane — CO₂ to CH₄.

Scientists estimate that the earliest biological entities began to appear on Earth more than 4 billion years ago. "There was a sort of primordial soup from which certain organic molecules were ...
