To change the shape of someones face you hate and toe nails to scratch the floor when you are guilty of something
You need something to help when you scratch.
protection on nail beds as well as survival (of our ancestors more than us) they are used to scratch and fight , today mainly helps with opening things , scratching an itch and so on.
The fingernail is an important part of fingertip function. It provides support for the finger pad and improves sensation. The toenail functions in a similar manner in the foot.
If we didn't have finger nails it would be hard to open soda cans and we would all need back scratchers for when we had itches? Seriously I really don't know, I do know that my boyfriend ripped one of his fingernails off and it was very very painful for him.
to scratch with, and women mark their territory with them too. for example when me and my man are .......you know, i always leave scratch marks on his back neck and chest, it's like telling others hey he's taken, or gives them a chance to get their a** kicked one!
I bet nature gave them to us to use as weapons.





I'm a bit stumped though how toenails can be used as weapons.


Lord knows some folks have some funky looking toenails!!





*maybe funky looking toenails are to scare off preditors?
pluck them off and then tell me if they are needed or not
to get in the way i guess
The purpose of finger and toe nails is an evolutionary way of protecting the tips of our hands and toes as well as several other uses such as prying, griping,digging not to mention asthetics. We just wouldn't look good without them.
actually balance
This is either a great question or an idle musing. Try this: Wrap all ten of your fingernails with tape. Now, try to carry on with your regular day. You'll find that fingernails help us scrape and scratch all kinds of things.





Start with washing your hair. Fingernails help you scratch your scalp and get the shampoo all the way to the head-ends of your hairs. Now, get some bread out of a bag to make toast. Without the sharp edge of your nails, it's not so easy. You'll notice right away that you can't scratch an itch. Try opening a ketchup packet at the fast food restaurant with your thumbnail taped over. We use our nails all day to get a grip and start a rip.





Fingernails have a few properties that are worthy of a head scratch (ha!). First of all, they're on your fingertips, right where you can direct them to handle all sorts of tasks. Then, they're hard. They cut into softer materials like corn husks, pea pods, and bark. This helps us feed ourselves and shape our shelters. They're made of keratin, a protein you make from your food. Since we're always wearing them down, they're always growing. They are created from the soft tissue underneath, the root or ';quick'; of your nail.





Because fingernails scrape and cut into so many things in nature, germs can live underneath them. So, keep your nails clean, and don't bite them. It can make you sick and make your hands look worn. We all notice nails. That's probably why so many women and a few men paint and polish them. They're the way your hands make a first impression.





Our nails are the big-brained version of claws. You need 'em. So eat right. Keep them clean. And scratch on.
To protect you finger tips and toe tips when you hit them with a hammer...
it serves as a protection to your fingertip and toe tip, kinda like a shield. when you grip something or step on the floor there'a a massive pressure on your upper part of your toe or finger. thus if there's no nail you may find it very hard to grip and also u'll feel great pain on your tip.
