Now, there's a start! If we posit the early rising group as the
defacto situation (I'll address that below), we could say that late
risers do this to be slightly out of sync with the early group, avoid
the power structure of the group, and thus, yes, get more (as Brian
said, lmao). That kind of slight tendency in some genes could be self
supporting, and tend toward creating a sub group, the genes from late
group not mixing so much with the early group.
This then begs the question, why is the early group the default? It
seems to me that the early rising times better match the daylight
hours. So straight thinking, logical types would find that the most
useful time to be awake, I guess.
The early risers are the people that attend to the day to day business
of life, absolutely necessary, but hard to think deeply around because
deep thinking looks like idleness. So, the late group attracts the
deep and weird thinkers, who need mental time away from the early
group. It looks like that's where you start to get a weak separation
of genes into Early Riser+Straight Thinker vs Late Riser+Bendy
Thinker.
Not fully coherent, but that's shaping up as something. Anyone got
something more / different?
