If you take the tree of life showing the evolutionary branch, you won’t be able to pick off a branch that includes all of the things you would think of as “fish” but excludes all of the things you think of as “not fish”.
The reason for that is that all land animals with a four limb body plan, including reptiles, mammals, and birds dinosaurs evolved from a family of fish called tetrapods. But there are still tetrapods in the ocean that you would think of as “fish”, and I don’t mean whales.

The state of office desks has been continuously getting worse my entire career.
The very first place I interviewed had small private offices with a door for everyone. They weren’t any bigger than a decent sized cubicle but were real separate rooms and most of them had exterior windows. I didn’t get that job though.
My first desk at my first engineering job was in a cubicle with real six foot tall walls, a window with a nice view, big L desk, shelves, filing cabinets, etc.
Then I got the same setup, but in a fabric cube. Honestly, not really a downgrade. I had that setup three times, and the only difference was how good the view was.
Then the same but no windows.
Then a smaller cube with a simple 6 foot desk and a single cabinet.
Then a line of 6 foot wide desks with privacy screens on three sides.
Then privacy screen on left and right only.
Then no screens.
Then four foot desks.
My current office is four foot desks that are hotdesked for most people. But we are also completely remote if you want, so I use my nice desk that I built at home 90% of the time.
