If an exoplanet had a light side and a dark side (like Earth's moon, slowly spinning in orbit to keep one face towards earth), might life evolve around the penumbra?

Assume it's too hot on the sun-facing side to support life and too cold on the permanent-night side. Can MeFi's planetary scientists suggest ways in which liquid water and life might evolve in the longitudinal band of twilight that crosses the equator and both poles?
