Do amoebas sleep?
Or do they just rest?
We tend to think every living being sleeps because we do, but that is not so self-evident on second sight. Apparently dolphins do not sleep, because they need to breathe. Reportedly they manage by resting part of their brain for a while, then switch.
Does consciousness require rest or does just thinking and other mental activity cause us to need sleep?
Consciousness in an amoeba, if we grant consciousness to them would not neccessarily require energy and thus require switching it off after some time.
There are rumors that politicians also do not sleep: they are in a continous state of dozing, which cannot be called sleep…
Other (sub)species that may not sleep: mothers and one-day-flies ( this maybe funny only for Germans )
