Paper Finding: One path forward is to continue the modeling approach with biofluxes as free ranging parameters and detailed photochemistry models while considering planets more and more different from Earth, no matter how vast the parameter space of imagined scenarios might be.

Paper Context: There are two separate but related paths forward. One path forward is to continue the modeling approach with biofluxes as free ranging parameters and detailed photochemistry models while considering planets more and more different from Earth, no matter how vast the parameter space of imagined scenarios might be. This exhaustive modeling endeavor has inadvertently begun for O 2 , with the resurgent consideration of false positives and different possibilities in terms of atmospheric mantle, surface and atmospheric chemistry, and photochemistry scenarios.
