It'd be interesting to come up with some scenarios for evolution on such a planet whose star decreases in luminosity as it ages (as opposed to more conventional stars that brighten as they age)-- perhaps life might begin in the cloud layers of an initially Venus - like planet, moving to the surface as the atmosphere cools and the oceans rain out of the atmosphere, and finally moving to a more Europa - like state with the oceans frozen under an ice layer.

Such stars are rich in carbon, and it is believed that the fall in brightness is due to the star's emission of carbon, which then condenses to a dense cloud near the star, rather than to a change in luminosity of the star itself.
