Earth is over 4,500 million years old. Massive bombardment of the planet took place for the first 500–700 million years, and the largest impacts would have been capable of sterilizing the planet ...

Project overview Oxygenic photosynthesis is the main energy input into the biosphere. It has sustained our civilization through agriculture and fossil fuels, and it has sustained a thriving ...

MIT scientists estimate that oxygenic photosynthesis — the ability to turn light and water into energy, releasing oxygen— first evolved on Earth between 3.4 and 2.9 billion years ago.

A study finds that the manganese-containing mineral rhodochrosite can be abiotically photooxidized by ultraviolet light under anoxic conditions that could have been present in the Archean Eon; the ...

Oxygenic photosynthesis replaces oxygen in the air with the assistance of energy from sunlight. In the absence of oxygenic photosynthesis, atmospheric oxygen would eventually be depleted.

If oxygenic photosynthesis evolved early, it could mean it is a relatively simple process to evolve. The probability of complex life emerging in a distant exoplanet may then be quite high.
