Evolution on earth is heavily influenced on dark/light cycles through its entire history. No evolutionary path that has received this influence can tell us anything about what would happen, on things that are highly correlated to it, for one that has never received this influence.

of course, but the reasons lions sleep far more than the day/night cycle requires are a factor that applies elsewhere, and thus might result in something similar.
