      It’s 1st grade biology!

      Yes, it is. Advertising the fact that you only know biology up to a 1st grade level is not the flex you think it is.

      Taxonomy isn’t biology, though. It’s a man-made classification system. And at the species level it’s much closer to binary definitions than spectrums. So maybe not the best analogy to make.

          But taxonomy aims (even though it sometimes fails) to classify organisms into rigid categories, which is exactly the thing you want to avoid with gender, right?

            Just like how we understand that species at a real level are actually a spectrum, we do the same thing with our (self-identified) genders. We feel a certain way about ourselves and find the closest available definition to provide to others. It may not be a 100% exact match to you and you will likely have nuance, but so do species.

            It actually is helpful, too because it lets others know how you’d like to be treated in a word.

            You seem to see taxonomy as separate of biology and by devaluing taxonomy as man made, you heavily imply that biology isn’t

      It’s likely easier for people to learn to love trans people than understand there are no fish… If that tells you anything.

    Just gonna swing by and drop this little grenade:

    If you believe “race doesn’t exist”, then this post also applies to you. If you can refer to different genders while also understanding that at the individual level definitions are fluid and blurry, then you can refer to different races while also understanding that at the individual level definitions are fluid and blurry.

    Fish absolutely exist cladistically, OP just didn’t want to admit they’re a land dwelling fish. You believe the implications of cladistics or you don’t, cowards.

    I’d also argue it’s relatively easy to separate fish-fish from land fish from land fish that became sea fish again to bully the fish fish.

        Seems so. Wikipedia tells there are seven classes of vertebrates:

        • Agnatha (jawless fishes, paraphyletic)
        • Chondrichthyes (cartilaginous fishes)
        • Osteichthyes (bony fishes, paraphyletic)
        • Amphibia (amphibians)
        • Reptilia (reptiles, paraphyletic)
        • Aves (birds)
        • Mammalia (mammals)

        So yes, fishes is the same thing as vertebrates.

        Probably because if you were a vertebrate living in the sea, you needed some sort of gills and fins and such. And those are what makes people assume something is a “fish”.

      This is like bemoaning the fact that doctors don’t treat “the humors” anymore. We gained knowledge that invalidated what we thought we knew, so we’ve updated our understanding. Unless you’re a taxonomical marine biologist, it’s really very unimportant anyway, I wouldn’t worry about it.

      No no, it’s that humans are technically in the fish group of evolution, even though it happened a LONG time ago. That’s what they mean by “cladistically”, there is no “clade” of fish. Look up “humans are hagfish by Clint’s Reptiles”. He explains it wonderfully

        It’s not even that we lack a way to define fish, it’s more that we lack a definition that isn’t arbitrary. One can define them as something like “vertebrates, except for all these ones that we don’t want to include”, but then there’s not really a clear reason to exclude all the amphibians and reptiles and mammals and such, other than that they don’t traditionally get called fish. Some of them even live in water, and a handful of fish can leave the water to a limited extent, so it isn’t even that.

        When it’s a grouping that we lack the definition for, then the group doesn’t really exist, even if it’s members do and we all gave a good idea of what are, for instance, fish. Basically the group ‘fish’ contains all the things you think are fish, which is problematic as someone else may have a different idea of which things belong in the group, and while that’s fine when talking coloquially, you can’t really use it when trying to discuss things in a rigerous fashion.

        We don’t lack a definition, we actually just have so many narrower definitions that we don’t need one for “fish” anymore. The old, broad definitions become archaic and often inaccurate as we gain more knowledge.

      Yeah I disagree with the idea that there is no such thing as a fish.

      It’s like saying that there are no striped animals because both zebras and snakes can have stripes.

      Sure, there is no common ancestor for hundreds of millions of years but that doesn’t mean that they aren’t a thing. ¯\_(ツ)_/¯

    I try to tell folks all the time that biology is not as simplistic as they think. It’s basically an endeavor of humans trying to make simplistic categories out of a naturally complicated clusterfuck. Some things defy labels, not everything fits into a nice, easy little box. Life is complicated. Get over it.

    Regarding “fish” Old classification relied on “phenotype” characteristics. And yes lamprey, a shark or a cod has little in common genetically. But they still share some common traits that distinguishes them considerably from whales, sea lions and seals. I still think the term “fish” is useful, and modern classifications rely more on genetics so I would say that the argument is semi void.

      They didn’t say that fish wasn’t a useful concept, they said that the more you delve into the facts, the less certain you can be that it has a definite meaning that can be pinned down scientifically.

      People think the science agrees with them that the world can be divided into fish and not fish, but that’s absolutely not what the science is saying, and their understanding is superficial.

      Similarly, the terms male and female are generally quite useful, but the people who think that there’s some kind of scientific and absolute binary distinction between them are just incorrect, and their understanding is superficial.

      Take “Spider” for example, that is a fairly well definied term for all animals in the order “Araneae”. But that doesn’t really work for the term “Fish”. There a many dozens of completely different orders with thousands of species that are refered to as “Fish”. It’s a bit like saying “thing that swims in the water”.

      When organizing the big family tree of everything that’s alive, you use clades, which means a group that all of the individuals in it have the same common ancestor. E.g. All vertebrates, wether mammals, reptiles, etc, have the same vertebrate ancestor. Mammals also share the same tetrapod ancestor, so they’re all tetrapods.

      Fish doesn’t work like that, because we don’t count all the its ancestors as fish (tetrapods have a common bony fish ancestor, for example, but you wouldn’t call a parrot a fish). But you know what a fish is. We call this a paraphyletic group.
