Very interesting. This gives us a good idea of what kind of life we might find on a planet without an oxygen rich atmosphere such as ours.

- BurningFrog 7y agoLife on Earth developed without oxygen. The oxygen only appeared 2.4 billion years ago, as a side effect of photosynthesis and the event is sometimes called the "Oxygen Holocaust", since it caused almost all life on Earth to go extinct. https://en.wikipedia.org/wiki/Great_Oxidation_Event https://en.wikipedia.org/wiki/Great_Oxidation_Event
- mirimir 7y agoYeah, that's the really cool thing. Most of the survivors likely live in the deep biosphere, well protected from oxygen. But some also survive on the surface, wherever there are anaerobic environments. Such as in some swamps and sediments, canned food, and far-gone wounds.
