> Carell’s team has shown how all nucleobases could form under one set of conditions: two separate ponds that cycle through the seasons, going from wet to dry, from hot to cold, and from acidic to basic, and with chemicals occasionally flowing from one pond to the other.

I've enjoyed Bruce Damer's explanation of related theory, "The Hot Spring Hypothesis for the Origin of Life". Search "goldilocks chemistry" for some helpful background and visualizations on this page - https://extendedevolutionarysynthesis.com/the-hot-spring-hyp...
