Regardless of the evolutionary history of nails, they now are used as a reverse pressure plate on the finger or toe which makes its tip more sensitive to touch. All these other ';answers'; are mostly folk tales.

Toe nails are a left over remnant from when we needed claws, birds wee is mixed in with their other stuff %26amp; I didn't think bee's had skellitons, but now I'm not so sure.
the reason we have nails is so that our fingers and toes don't crumple up at the tip when they come into contact with a solid object.





bees have their skeleton on the outside of their body, as do a lot of insects.





and, yes birds wee. it gets mixed with their poop!
to scratch ya calves with lol
In evolution, characteristics that are beneficial are retained, and those characteristics that are of no value will eventually fade away. (Those that are harmful will become extinct).


*If you believe in evolution, from the first mammals to us, toenails are the result of unneeded claw-like characteristics fading away. At the point they are at now, they cause no harm or benefit. So, evolution would not ';work'; any harder to make them go away completely. By the way, to me, this simple idea is the most convincing proof of evolution. Exactly the same as why guys have nipples. Probably at one time, males and females could provide milk to young. Eventually, that need faded, and male breasts faded. At this point, having male nipples doesn't help to survive, or harm. So, there is no ';need'; for evolution to get rid of them any further.





*Birds wee- I assume you mean urinate. Kind of- they release kind of a poop/pee mixture. That's why when they get your car, it's always so runny.


*Bees- They don't have bones. They have an exoskeleton like other insects.
toenails are to protect the toes from knocks


they are very useful as i found out last year when as a result of a fall in the bathroom i lost my big toenail and was very glad when it grew back





birds producea mucousy urine which they deposit with their faeces





bees have an exoskeleton so their limbs are mobile


you cant move without a skelteon if youre an adult artropod
they protect our toes.
