What is the most recent common ancestor of all organisms that require sleep?

If it is unknown, are there reasonable hypotheses about this organism's characteristics? Could it have extant descendants that don't require sleep? Is there a taxon that contains all sleep-requiring organisms? Does it also contain non-sleep-requiring ones? Does it contain one or more taxa, which contain both sleep-requiring and non-sleep-requiring organisms?

An alternative question. What is the most recent common ancestor of all organisms that can be awake?

There was a discussion not so long ago about sleep, and someone who seemed to know what he was talking about, argued that it's not obvious what evolved: the need for sleep or the ability to be awake.

Can we even meaningfully say that amoeba is awake? Or asleep?
