Very interesting! Especially considering the theories behind the starting point where life went from anaerobic to aerobic respiration.
I wonder if the models will have to be redrawn. What caused that methane layer to dissipate? What introduced that oxygen-heavy layer, if it wasn’t CO2 respiration from new upstart life?
Modified certainly!!

I don’t think so. They’re still saying this is consistent with the lower atmosphere being oxygen poor.
