A celestial body that was tidally locked and had environmental constants (light / dark / hot / cold / etc) would be such an interesting situation.
Granted the place in question could support life, I’d imagine that forms would become hyper-specialized to their unchanging environment. No daily or seasonal shifts like night or winter (or day or summer) to waste adaptive capacity on.
Anyways I’m gonna go make some money then touch grass. Enjoy the day frens.
