It does though. Base 10 is entirely due to humans having 10 fingers.
Base 12 is not organically common, it's incredibly rare even with the modern counting systems we've discovered...
The frequency of emergences (based on language families that use them) are: 4 ~1 time, 5 ~4 times, 6 ~3 times, 8 ~2 times, 10 ?? times, 12 ~3 times, 15 ~1 time, 20 ~9 times, 20+5 ~2 times, 23 ~1 time, 24 ~1 time, 27 ~1-2 times, 32 ~1 time, 60 ~2 times
If we had 8 fingers, or 3 fingers, or 15 fingers, we would still be using base 10. It's just that the value of "10" would be different each time
Took me a bit but indeed. I love this fact now
It's the classic 'there are 10 types of people...' joke, but for a number system other than binary
Yes but (1) that isn't the only base system humans use and (2) aliens could use a base system entirely divorced from their body parts. So number of fingers doesn't have to dictate which base system is used.
