>>I will take a look at those nonfiction lists just as soon as I get through my pile of unread nonfiction I already own, my 'saved for later' lists on various online bookstores, and the rec list I have saved as a word document, lol.<<
I know that feel.
>>There is actually a lot of scientific research that suggests humans could easily adapt to Mars's day length. Most people's internal circadian rhythm is actually around 24.5 hours, it is just periodically reset by the day's light/dark cycle. <<
Interesting.
I still like the Mars idea, though, and may throw it into today's fishbowl on "flipping expectations."
>>This reset is how (most) people recover from jet lag and adapt to new time zones, <<
I have no trouble adjusting to time changes, but it resets to the same orientation of preferring second-shift.
>> and one of the main reason N24 is more commonly recognized in blind people with zero light perception.<<
Yeah, if they can't pick up the light cues, it has the same effect as people living in caves.
>> Why sighted people develop N24 is still a medical mystery :)
Diversity. A species with more natural variation is better equipped to withstand any challenges than one with little variation. What can be a nasty disadvantage in modern times would've been an asset to hunter-gatherers. It's better to have someone awake at any time in case danger approaches the camp, and that person will be more awake if they're a natural night owl than if they just drew the short straw to stand watch. In a longhouse or other communal dwelling, that person is also available for night or predawn baby-tending.
