Polyphasic sleep seems to be the natural sleep-cycle of humanity, as proven through natural circadian rhythms.

Sleeping for 8+ hours at one time, on a regular basis, may just not be natural for a significant percentage of humanity.

In which part of the world do healthy adults regularly sleep for 8+ hours?

Isn't it the default in the western world? That's what we do in my family at least... I haven't really heard of people not sleeping just one 8 hour sleep every night.

Or maybe you're making a reference to the chronic lack of sleep that seems to be the rule in the US, but it doesn't seem to be necessarily case elsewhere. Average sleeping time is just a little above 8 hours in France and Belgium, my countries.
