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?

The rigidity of it would be different without the nail. Try grabbing something with a sponge. It won’t work usually because the sponge flexes backwards, even with something supporting the middle.
