- Comment on Isn't it weird that we have exactly five fingers and five toes on each hand and foot. 1 year ago:
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 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.

- Comment on Sign language is just radio communication but on another frequency 1 year ago:
Yeah probably true. I only thought to look it up because I knew active and passive sonar was a thing.
