Re: A big misunderstanding
Thanks, that's a bit clearer. Still doesn't explain (to me) where the atmospheric O2 came from in the first place if it weren't for photosynthesis.
This article seems to suggest that the huge amounts of atmospheric oxygen which appeared back then were partly created out of volcanic CO2 by some geological process also involving volcanoes. Or did I misunderstand everything? *scratches head*
