@zatnosk "fish" is a category based on common attributes, not lineage
@zatnosk I mean I didn't invent biological categories but they're not arbitrary
@noiob but fish apparently is. Whales used to be considered fish - an old danish word for "whale" is "hvalfisk" = whale fish.
Sorry, I don't want to make it an argument. I know fish isn't a technical biological clade, but it's socially constructed which words get to be considered a clade, when a lot of the words are older than cladistics.
@zatnosk tbh I just like the fact that "fish" is a pretty loosely defined category (that definitely excludes mammals nowadays)
@noiob "dinosaur is a clade because it's a clade" is what I'm hearing.
