    Does anyone know what is responsible for Oxygen creation in the early atmosphere? I thought Orgoman said it was heterotrophs?! I can't find an obvious answer googling.

    Thanks!

    It is autotrophs because autotrophic organisms converted light energy to usable energy and O2, like present day plants. O2 then allowed more complex organisms to develop.

    Yeah I think its photosynthesis by autotrophic organisms. After the atmosphere was converted from a reducing one to an oxidizing one, chemical evolution ended. Lol
