Recently smashed my finger and lost the nail and it got me wondering what is the biological / mechanical / etc function / reason for fingernails? Sure it would be harder to grip little things, but is there a structural reason why our digits need these things?
EDIT: Follow up question. What is different about the skin underneath your nail that makes it so painful when initially exposed to air?

I feel like that cringey feeling you get when you bend a nail or get something stuck under the nail must be evolutionary, it feels so awful because that’s nature telling us to stop doing that thing immediately because you need to keep your nails.
Not based on science just feeling 🙂
