That is also what I am referring to. Energetic activity is required to live and to reproduce, those are the normal activities. An active creature may have evolved a state of dormancy for various reasons, but there was never an organism in a state of pure dormancy.
- jldugger 1y agoDo sponges sleep?
- throwawayffffas 1y agoPresumably. Some jellyfish sleep[1] But do fungi and Archea sleep? My guess based on what we read is yes and no.

- rkomorn 1y agoOf course fungi sleep. That's how we can catch them in order to eat them.
- jldugger 1y agoYea, but at some point this is probably gonna strain the colloquial definition of sleep. So I went for one of the oldest and perhaps simplest animals around, to examine the "creature" angle in extrema.
- jjk166 1y agoThey certainly aren't exclusively inactive, which is all that matters for this discussion.

- heavyset_go 1y agoSleep isn't pure dormancy, though. Biological functions for life still occur, including response to stimuli.

- jjk166 1y agoThe fact that even when sleeping an animal can't remain dormant and survive is pretty good evidence that dormancy was not the ancestral state.
