What they meant is that we evolved in a way that made teenagers having shifted cycles, going to sleep later and waking up later. We're not living in tribes anymore, but evolution is slow and we still cary these biological traits. It therefore hurts teenagers to wake up as early as adults. The point here is not about leaving them more time to socialize in the evening.

Wouldn't accommodating them make evolution slower? Those that have traits making them able to wake up earlier should be "rewarded" if you want to bring change.

Well, I didn't come to this thread expecting a eugenics-based argument in favor of medically unsound school start times, but here we are.

I was trying to comment on the irony in adapting to our evolution instead of the other way around. I wasn't trying to advocate any solution. Clearly it didn't come out right based on the replies I got.

Do you realize you're talking about killing people? Evolution happens when the less fit die or otherwise fail to reproduce. If you want to evolve more nocturnal teenagers, the least unpleasant implication is that you want late sleepers to stay sleep-deprived so they'll die in accidents.

Our goal is not to control evolution, it is to let people exist within the biological constraints they have.

We evolved to be remarkably adaptable species. Our social and environmental conditions influence so much, that there is zero reason to assume that any particular behavior in prehistoric time is fixed and not just adaptation.

Moreover, half of those "past evilutionary people were like this or that" is guess made out of flimsy evidence at best. It is best we have maybe, but not accurate. (For that matter, majority of popular "past people were x" is wrong even for periods where we have a lot of documentation of).

My anecdotal evidence is that when I do sleep at night, eat less and have a regular sex, my body works very well in my 30s. Things change instantly once you lower some grips. Something in me is not just adaptation, but finely tuned core mechanisms. In fact, our current live is very different from what serves well to us. And this is even exploited to large extents – see ads, politics, social irrationality. If it were mere adaptation, then we could be rational and adaptive af.
