- jameshart 4y agoLuckily they evolved feathers and manage just fine.
- ben_w 4y agoThey had feathers when they were dinosaurs, and they’re smaller now. I can’t usefully comment on most of the actual science in that paper, but I already had reasons to expect significant changes to the total mass of the atmosphere before reading it — the difference between today and the pre-oxygen apocalypse era (~2.4 Gy) implies at least a change of either 0.21 bar (if the oxygen came from the water) or 0.07 bar (if it all came from CO2). I have no idea what to also anticipate from geology, impacts, or other things life might do besides the GOE.
