The parent comment only mentioned humans being diurnal, not other animals.

There's a number of strong evolutionary forces that explain nocturnality: niche differentiation, crypsis, a predation arms-race, water conservation, etc.

I'm not sure your point about humans vs other animals.

Are you suggesting sleep evolved for a different reason in humans than it did for our ancestors and the millions of other species that sleep?
