Purple earth hypothesis suggests that early photosynthesis wasn’t chlorophil based, but on a simpler molecule (retinal) which is purple colored. The Canfield ocean was supposed to have followed this time yielding a turquoise life, where the ocean was anoxic and sulfidic. That was then replaced during the great oxigenation event which lead to the current green earth.
If you look at stuff like the purple earth hypothises, the Canfield ocean, I’d definitely go with life finds a way.
I don’t know either of these terms. Can you give me a tldr?
