    As our evolution slows

    Well that’s bullshit.

    But yes, adapting to new things is usually a generational thing. And tech. progress accelerated past that about two generations ago. This already creates issues with parents and teachers not being able to teach the children proper media competence (because basic IT knowledge never penetrated to them either). Which leads to the misinformation crysis.

      For evolution to happen, people need to die.

      Specifically, they need to die before they reproduce.

      Evolution has slowed because modern society makes it easy for most people to live long enough to reproduce.

        I don’t know that it would matter much as long as there is sexual selection rather than natural selection. For instance, if a random cross section of a population dies, then there’s no evolution because there’s no reason that the survivors lived to pass on genetics. Is that not correct?

          A one time random die off of the population is too small of a time scale, likely. While it is possible for mutations to occur that don’t confer survival advantage, those likely get mixed and blended out of the gene pool. Evolution requires traits that provide sustained advantages to emerge over long periods of time and for those without those traits to fail to reproduce.

        Humans still select for more gracility on average. And social selection is part of evolution too (and not only humans do it).

          the state of being gracefully slender.

          Im Learning a new word today but I still dont understand after looking up. Could you clarify context?

            Well, human skeletal gracility compared to other hominides. There was a study years ago, that human still sexually selects for even more gracility (on average), while already getting to the point, where the bones get too thin to properly support their other roles in metabolism.

            Ah, and about the “evolution slowing” part being bullshit; maybe 10 years ago already? Other studies that disproved the myth.

    This is exactly why colonizing Mars would be a nonstarter. We’re barely coping on our planet of origin. Although many of the problems listed are side effects of unmanaged capitalism rather than society as a whole.

    Majority of humans may not have the genetic adaptations necessary however there are some already who can already tolerate much higher temperatures while consuming much less water so there may be some humans that won’t be as adversely affected by the warming planet. It may depend on whether or not they are able to maintain food sources.
