    There are anaerobic bacteria that don’t need oxygen to survive. That was the norm before The Great Oxidation Event when cyanobacteria started releasing oxygen into the atmosphere during photosynthesis. Prior to that there was very little oxygen in the atmosphere, and anaerobic bacteria ruled the world.

    After the GOE the high concentration of oxygen killed off most of the anaerobic bacteria, and what was left were organisms that made a blood truce with oxygen. Aerobic organisms gained incredible power from utilizing oxygen for metabolism, but eventually die from the accumulated damage the oxygen does to them.











  • Communities tend to attract like minded individuals. It’s not that everyone is exactly the same, but those that are very different or have very different opinions don’t generally stay for long. That said, even within those like minded individuals there’s a wide spectrum of opinions.

    For me there are a handful of topics I know I’ll get down voted for sharing, because it goes against the majority. And that’s fine, it doesn’t stop me from sharing my opinion, and I don’t really mind the downvotes. I think in general though as long as you’re able to share your opinion with nuance and self awareness, and it’s not something mean or hateful people will hear you out.
