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.
Fish do not exist because of pedantic technicalities? Reality isn’t real

Wow. This video was great. Thank you!!
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)_/¯
Just because we lack a definition, doesn’t mean something doesn’t exist.

Scientists said the oceans would run out of fish by 2048. In fact, fish stopped existing today. Sick burn.
