If Insects are considered crustaceans and birds are reptiles, would humans (or all tetrapods rather) be fish.
When looking at an evolution chart for fish, I had to go pretty far down to get down to tetrapods. And they're pretty close to lungfish and coelacanths. In the chart it says Tetrapoda (not considered fish), but wouldn't they be? I always hear people say insects are actually crustaceans, and birds are reptiles, so would the same not apply to all tetrapods being considered fish. Would birds be reptiles AND fish!?!?
