    That’s fair. Honestly, all of taxonomy is just lines we draw, and all of evolution is really a fuzzy gradient. We can’t even figure out where the line for ‘human’ begins, because that’s also a meaningless term, really.

    So the fact that we’re fish is as meaningful (or meaningless) as the fact that we’re human.

    (And thanks for the link! That’s a cool, uh, ‘fish’.)

    Sure, but isn’t the point that what we’d call ‘fish’ back when everything lived in the oceans, like pre-Devonian, the ancestors of all modern life?

    We can’t out-evolve our clade, so all land animals are fish? And also we’re all amphibians, and everything directly leading to us? Insects, plants, and fungi are separate, but we’re technically fish?

    Or am i misunderstanding that?

    (e: if there are no ‘fish tetrapods’, where did tetrapods come from?)

    It’s sneaking up on creationist levels of ‘science’, like where they argue recreations of Australopithecus are just ‘imagination’ and present their own version of Lucy as as a quadriped, completely ignoring the overwhelming evidence from her skeleton that she could not have walked that way (and also ignoring that we have hundreds of other specimens of her species).

    It really seems that lots of people’s conception of these fields is based on very outdated concepts, either unaware or ignoring all the evidence and advancements of the past 50 years or so.

    Also, as you move throughout your life, those attachments can cause stress in places that build up, and your bones will show all of that. For instance, even though all humans have the same soft tissue connection points, we can tell by a skeleton whether a person had a life of hard labour vs relative luxury, whether they were an archer with stronger and more stressed arm muscles, etc.

    If tail vertebrae, for instance, have spent their life supporting and moving a heavy amount of soft tissue, those connection points will look much different than a similar tail of skin and bone with far less weight to bear.

    So now, we have a pretty good idea not only where soft tissues attached, but their relative size, strength, and use.
