      Would you recommend anything to read about this regression to the mean idea?

      Regression towards the mean really.

      Height, for example. You have gene variants that would tend to make you have a certain height in a particular environment: but also, height is influenced by essentially random factors. Maybe development noise. maybe muons.

      Your kids get a random sample of your genes and a random sample of your wife's: on average, their genetic inheritance is the same as the average of pop and mom.

      But your kid's random noise is not linked to that of the parents: it is as if the dice are rolled again. I'm sure we could easily up with an exact D&D model for this.

      If you are very tall, you most likely have goof height genes _and_ some developmental luck. You kid will get a sample of your genes, but he doesn't inherit your developmental luck.

      One last key point: if you pick a bunch of extra-tall parents and stick their kids somewhere where they'll end up marrying each other, say on an island - regression does not continue. Dice have been re-rolled. You'll have a tall population. So natural selection is possible.

      Which means that fairly significant eugenics is trivial. This subject comes up indirectly in science fiction: often space colonization is imagined to occur with a picked group, healthier and smarter than average. The ensuing population would be different from us.

      Was thinking, how science fiction authors actually understood this? Not many that I can think of. Heinlein, certainly. Harry Turtledove understands it - but then, he did flunk out of Cal Tech, which is, I think, more of an honor than graduating from Harvard.

      Any series with a galaxy spanning human civilization that's lasted for millennia that doesn't have major biological differences between the human populations of different planets implicitly fails to understand this.

          Well, if they had super-easy transportation, say faster-than-light teleportation, you might get leveling gene flow. But that's what it would take. Or, deliberate forced genetic standardization.

          Would take something like FTL teleportation that also could be run by people of close to average ability and with low energy expenditure - otherwise it would be something that only the top of the top engaged in.

          Starship Troopers discussed some of this, but mostly differences were chalked up to some planets/moons having higher mutation rates.
