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?)
