A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

- The entire showerthought must be in the title

- 3.1) NEW RULE as of 5 Nov 2024, trying it out
- 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).

- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

The wikipedia article Polydactyly in stem-tetrapods has some explanations on how we ended up with 5 fingers and toes.
The gist of it is that tetrapods (four-limbed vertebrate animals) evolved from a fish similar to a lobe-finned fish that had 5 sets of bones in each of its fins that evolved into fingers and toes. Some tetrapods have subsequently lost digits but the basal state was five.
There's a book, Your Inner Fish by Neil Shubin that's full of this kind of stuff. Highly recommend.
I love it. So many things in the world don’t really have an “explanation,” they have a “story.”
The reason they are as they are is just because of prior conditions.
Amazing book. I recommend reading it if you're interested in evolution.
