Feedback: I like your addition to the main page on the Great Oxygenation. The suggestions you made on talk pages were also evolutionarily relevant and well-thought out. I suggest continuing to think about this idea of oxygenation and diversification. Its really cool. Which is a pre-req for the other? Or do both get in positive feedback?
