EtymologyEdit

Borrowed from French oxygène (originally in the form principe oxygène, a variant of principe oxigine ‘acidifying principle’, suggested by Lavoisier), from Ancient Greek ὀξύς (oxús, sharp) + γένος (génos, birth), referring to oxygen's supposed role in the formation of acids.

    • 2013 September-October, Katie L. Burke, “In the News”, in American Scientist:
      Oxygen levels on Earth skyrocketed 2.4 billion years ago, when cyanobacteria evolved photosynthesis: the ability to convert water and carbon dioxide into carbohydrates and waste oxygen using solar energy. The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light.
