      Mutations are random. The survival of specific mutations in a species however are not. That’s why evolution isn’t random.

      It *is* random. Not every negative change vanishes, not every positive change is preserved, and neutral changes happen regularly and also may or may not stick around.

      The survival of specific mutations doesn’t stop being random just because the *chance* of that mutation surviving is partially reliant on whether or not it’s beneficial

      I don’t think you understand what the word random means. 😀

      “Random” doesn’t mean “coin flip” If one thing has a .9 probability of happing, it’s still random. If it has a .1 probability, it’s still random. Random doesn’t mean “equal chance of happening or not happening”.

      No, but it does mean that as time progresses, chances of a detrimental mutation remaining goes to 0, while the chance of a beneficial mutation remaining goes to 1.

      Not a bit of it. Plenty of detrimental mutations don't actually affect reproductive fitness, so they don't go anywhere. Plenty of beneficial mutations have an energy cost that doesn't translate into increased reproductive fitness, so they disappear again.

      Even the idea that there's an objective definition of "detrimental" and "beneficial" that stays consistent over time is obviously projecting our values onto the uncaring universe

      Evolution is only even *possible* because there's a certain baseline level of diversity in alleles made possible by ongoing random mutations that stick around for long periods of time

      People get the timescale twisted in their heads, like the existence of the allele has to happen well before the actual event causing selection happens If it didn't happen until then it would be too late, there'd be nothing to select

      This concept was mocked by anti-Darwinians as "hopeful monsters" because, again, they didn't grasp the timescale involved (a fish egg hatches a lizard that starts to drown but makes it to land just time?!?)

          But that's what most mutations are like Oh, some humans are melanin deficient, and that's bad because skin cancer, but it's also kind of good because vitamin D, so it's a wash People start living indoors most of the time and skin cancer is now rare? Hey awesome
