Not my post. I’m a third person who came along already knowing this fact, and when you posted a link, I was expecting it to be this Scishow video which explains why there’s no such thing as a fish (or, alternatively, there is such a thing as a fish, and people are included in that category) in much greater depth.
But yes, QI is great! I miss the days when whole episodes could easily be found on YouTube.
The TL;DW is: in cladistics (which is the preferred way of classifying animals these days), there’s no way to include all things that we would call “fish” without also including all mammals, reptiles, and birds. So either people are fish, or fish don’t exist.
…I’m gonna need an explanation on that first point
Here you go.
Huh. That wasn’t the video I was expecting it to be.
QI is a treasure haha. They do get things wrong sometimes, but I instantly thought of it seeing your post.
