Reply to comment by Delamoor in TIL Pluto hasn't completed an orbit around the sun since its discovery. Pluto's orbit takes about 248 years, and Pluto was discovered in 1930. by irbinator

>We aren't even entirely sure why it evolved here,

Baseless speculation but if sleep is a time for recuperation, could it just be that complex organisms need downtime to process energy, slow down for a while, etc.?

This is my assumption. I think we would have to have some sort of resting time. It's interesting to look at how certain organisms have adapted to the regions of the world where there is not night/day cycle for extended periods. Cannabis Sativa, for instance, requires longer nights of about 12 hours in order for the plant to begin flowering. However, Cannabis Ruderalis, which was originally discovered in siberia, automatically flowers after around 30 days because as you can imagine, there is no break in light in the region for many months.
