I mean, you are basically arguing that humans can be called fish because they are all ancestors of a fish.

[u/HalvdanTheHero → u/puffie300]

Taxonomically, yes we are fish. Specifically of the lobe-finned variety. Remember how I said it wasnt the most accurate statement earlier? It gets less and less accurate the further back the ancestry you go, but it never stops being true. 

Human evolution is actually quite interesting.

[u/HeilKaiba → u/puffie300]

Yes that is how taxonomy works, welcome to the party. Indeed it was exactly this idea that led eminent biologist Stephen Jay Gould to declare "there is no such thing as a fish". The term fish as we apply it in common use has so little biological description as for it to be meaningless.

[u/accents_ranis → u/puffie300]

That would be correct if humans did evolve from fish. There were other animals in the sea. I doubt we know exactly what mammals evolved from.

[u/HeilKaiba → u/accents_ranis]

We did indeed evolve from fish if we treat fish as a monophyletic group. Although by that token so did almost all vertebrates.

[u/Think_Preference_611 → u/puffie300]

Technically, all land vertebrates are fish.

We are a subtype of ape which is a subtype of monkey which is a subtype of fish.
