    “Survival of the fittest” is itself a naive view of evolution. “Mutual Aid: A Factor of Evolution”, by Peter Kropotkin, was a direct response to that shit over 100 years ago. It was a precursor to Kin Selection Theory developed in the 1960s. It gave the idea a firm mathematical foundation and is largely accepted by biologists today.

      The idea itself isn’t wrong, the fittest individuals (those who have the most offspring) are always those whose genetic material will be best represented in the next generations. Kin Selection Theory just includes the fact that even selfish and thus fitter individuals which are helped by altruistic ones usually carry some altruistic genes which they propagate.

        except that this fails to explain why animals like ants and bees have specifically ended up with most of the individuals being unable to procreate at all, clearly for them it’s more beneficial to enable your mom to have more siblings than it is to have their own offspring.

        even selfish and thus fitter individuals which are helped by altruistic ones usually carry some altruistic genes which they propagate.

        It’s more useful to model the genes as selfish, not the individuals. A queen bee/ant won’t survive long enough to produce fertile offspring if her infertile offspring, each a genetic dead end, doesn’t provide for the hive/colony. That genetic programming isn’t altruistic because it doesn’t help rival colonies/hives, only their own.

        So no, the individuals aren’t free riding on others’ altruism. It’s more that genetic coding for social groups is advantageous to the gene, even if localized applications of those rules might seem disadvantageous to the individual in certain instances.

        But then you introduce parasitic organisms, which prey on the more selfless and mutualist functions of complex species. And you end up with a cyclical rise and fall of survival strategies.

        Predator organisms proliferating in periods of organic wealth and collapsing when they’ve depleted the reserves.

        Meanwhile, prey organisms trade their mutualist reproductive impulses for traits that are defensive and alienating from their kin… until the predator collapse, at which point they can open up again.

        Optional survival varies with the historical movement, which is driven by the strategies that preceded that moment.

        Fitness isn’t a solved problem, it is a constantly moving target.
