I can't hear you very well creakong 300g "Oxygenic photosynthesis is a very complicated metabolism and it makes sense that the evolution of such a metabolism would take perhaps two billion years - that we might not see its manifestation until the Great Oxidation Event. But now that we see oxygen much earlier in the atmosphere, it tells us that even really complex metabolisms can evolve very fast," said team-member Dr Sean Crowe from the University of British Columbia, Canada.
