Pistachios and other nuts. To eat the nice part inside, one has to pry open the outer shell which was hard to do without nails. Nailless persons went hungry and sometimes starved to death.
Stingers too. Some of the nailless persons thought, ok, at least maybe i can climb that tree and steal some honey from the hive. They didn’t know what bees were, because nailless persons never survived to tell other nailless persons about stingers, which they couldn’t pull out because they didn’t have nails.
At this point you may ask, “why toenails then?”. Well sometimes a person has his hands full, and needs to scratch their leg. Without toenails its hard to do, and one has to rub their leg even harder with the nailless leg, which can cause one to lose their balance, fall and die a horrible death. So yeah, toenails.
Now you might wonder, ok that was then, before tools and home delivery. Why do we need nails now? Well aside from still needing to scratch an itch it’s to scratch nails on a chalk board to get annoying persons to shut up.
i get what youre saying and its mostly correct, but there was no humans or human like creatures without nails. most major features already evolved when we were early early mammals. like the very earlier mammals had claws that slowly formed to fingernails. and i dont think it would be common for any one to not be able to get into a nut or get a stinger out. those are good examples of uses for nails, but not how they actually formed through natural selection.
its more accurate to say that the sharpness of claws stopped being useful and stop being selected, and overtime devolved into nails. since it would no longer mean death to have smaller claws.
similar to humans not having body hair, its not a be naked or die kinda thing. just a trait that stopped being geneticslly maintained due to unnescscary
They're to provide something to clean under, to make sure that you're being thorough while washing yourself.
That way you can just look down at your hands and feet (people used to wear sandals so their toenails were visible) and know whether or not you're taking proper care of yourself.
Because if your fingernails are dirty, then you absolutely have dirty hands, and might end up getting food poisoning from eating something with those hands, or picking at a scab and getting an infection, or...

Here I was thinking to provide the anxiety something to chew on.

This is a joke subreddit.
omg my bad lol. i just saw explainlikeimfive in my head
I also didn't realize at first, lol. Though the bee part made me scroll back up to see which subreddit I was in.
I didn't realize what sub it was, either. I'm not subbed here, but Reddit likes to surprise me with random subs like that.

Say, Calvin, let me look at your hands.
When you can scratch someone else's itch, they want to boink you.
They want to make scientific progress?
No nails, can't peel oranges properly
Very little now, they are vestiges of the claws that were useful for the arboreal apes we are the descendants of.
When she gets them done right, I'm enticed to help procreate.
Without them, how would babies scratch their mothers and themselves!
Probably claws morphing to fit around tips of the fingers/toes.
Evolution can’t just get rid of something, it has to evolve it out.
So us having fingernails is likely the remnant of an older mammal that had claws that eventually evolved fingers and toes.
Pretty sure claws are made of keratin (like cat claws), and so are our fingernails.
Evolution couldn’t just throw away the claws, so we have fingernails and toenails instead as a natural part of the evolutionary process.
And the nails stayed around because they were/are useful to have for humans.
They're called nails because they hold the skin onto your body like it's nailed down
To scratch itches! :)
For the scraping of windows like little Danny Glick.
