Rather than info, it looks like a DIY. Goes like this for me: depends on who; babies sleep anytime, so do old folks so I'd guess it depends on lifestyle/function in the community. In a semi-nomadic group it would make sense that there is a watch all the time (predators, eh?), so some adults would be sleeping or waking all the time, depending. Lynnet's idea fits the life of settled farmers/neolithic.
