  • Evolution did not code us to avoid wood chips. There’s no “wood chip aversion” gene. It coded us to seek out potato chips.

    Again, I just think this is completely wrong. Evolution definitely does not only code us to go towards things we want, it also codes us to avoid harmful things. Evolution optimizes on all fronts at once.

    We risk mischaracterizing the nature of evolutionary forces by assigning to it a level of forethought it does not have.

    Evolution is a concept so obviously it doesn’t have forethought, but it doesn’t need that forethought to still evolve in a given direction. Natural selection drives evolution to whatever is preferable - if that includes an aversion to incest, then natural selection will select for that trait, given enough time.

    So the whole point I am making is that aversion towards incest is not rooted in primary drives but rather in the socio-primate drives.

    What evidence or arguments do you have for this? Aside from what you’ve presented already, as that has not been convincing. My explanation seems consistent and simpler and occams razor would prefer it.



  • It’s the same reason that we have laws against incest. Had laws against homosexuality.

    I don’t think this is right. We have laws against incest, because we were programmed by evolution to think incest is bad. The causal chain is:

    1. Incest lowers survival rates,
    2. Evolution causes humans to find incest disgusting to increase survival rates,
    3. Humans create laws to abolish incest because they find it disgusting.

    Homosexuality is not like that at all, if I understand correctly (which I may not, tbf). Homosexuality may in fact be a evolutionary trait that is selected for in a certain sense, or it may just be a side-effect of other evolutionary efforts. For instance, having a homosexual uncle could be beneficial to you, as he would spend less time taking care of his own kids (obviously won’t have any) and more time taking care of you. The uncle’s genes would have no incentive to do this and evolution would not pressure the uncle to become homosexual, but your common ancestor (your grandparents on one side) would benefit as your genes would be helped along by your uncle, and so evolution could have caused homosexuality to occur ever so often, to produce one of these “helpful uncles”.



  • While surely there is some genetic component at play there it appears to be primarily motivated by the primate social adaptation system.

    This seems like a strange argument, because “the primate social adaptation system” is also ultimately governed by evolution. Obviously a primate group with a social tendency towards incest would have worse survival rates than a primate group with a social aversion to incest, and that social fabric definitely is tied to evolution (unless you mean to imply that our social fabric did not arise from evolution, but I don’t think that’s what you’re saying.

    Also, I don’t see how this can have anything in particular to do with primates and their social constructs as incest is avoided by all animals, as far as I am aware. It is not a purely human or primate thing, incest is bad for all animals and so they have all evolved via evolution to avoid it. I’d say the Westermarck effect is just the result of that evolution - obviously humans can’t directly read genetic code, so the mind assumes that whoever you grew up with must be your close relatives, and that’s good enough of a signal in 99% of cases, so that’s what evolution went with.


  • You can’t really definitively prove a theory like that I think. I’m no biologist so I’m not an expert by any means, but we can’t go back in time to see why evolution did what it did. We can only guess from what we have right now.

    That said, such an “ew” response to incest surely is not just coincidence. It must have arose for a reason, just like all of our emotions evolved for a reason. For example, we also experience disgust when smelling or tasting rotten milk, because drinking rotten stuff is bad for survival too, so evolution made us have that response, because it would lower the chance of us drinking spoiled milk. There’s nothing “inherently disgusting” about incest or spoiled milk. We only find those things disgusting because they are bad, evolutionarily speaking.

    And btw this isn’t restricted to humans obviously, all animals avoid having offspring with their close family, so this is a very deep-rooted behavior.










  • For slet ikke at tale om hvor meget man bliver holdt i hånden.

    Åh det er så irriterende. Jeg tror det er et resultat af at mange store spil med store navne som Lego forsøger at tiltrække et publikum der slet ikke er vant til videospil. Jeg oplevede det også da jeg spillede Indiana Jones and the Great Circle. Det var tydeligt at tutorials osv. var sat efter laveste fællesnævner. Det er sikkert rart hvis du er hardcore Indiana Jones fan og aldrig har spillet videospil før og bare gerne vil prøve det spil pga. brandet, men for os andre kan det godt være lidt belastende.
