Sure, but I was responding to someone who was defining wasp (the common word) based on clade (using scientific words).
I’m fine with common parlance words for things. What I had issue with was arbitrarily restricting the definition of wasp to a specific clade, which would exclude ants and bees, and also a whole host of at the very least wasp-adjacent animals which would now be stuck with no real way to describe them.
(Also, yes, fish is a rubbish scientific word. We’re far closer cousins of salmon than sharks are. By any reasonable definition of fish, at least biologically, we are fish. You could redefine “fish” in the same way we define “tree”, i.e. based on structure and not on ancestry, but by that definition whales should still be fish. The word “fish” shouldn’t be allowed within 50 metres of cladistics.)






You do realise water can fall from the sky, right? 100°C might not be too useful for outside temperatures, but knowing if there might be ice on the road or not seems like a useful thing to know.
Also, as a maths teacher, having frequent negative temperatures makes working with negative numbers a lot more intuitive for students. The fact that Americans apparently use 1 for the ground floor means I’d lose out on both of my simple real-world examples of negative numbers.
