Finger nails and toenails are evolutionary remnants from the days when our ancestors needed claws for climbing and eating. Did you know that humans also have a residual tail? Also an evolutionary leftover, no longer needed, but still present

Nails are to protect the digit end and provide a support when using the digit, it's the same substance as hair which is to protect body areas prone to temperature or rubbing, such as the armpits.

I Think it is to do with our evolution, we lost our tails but still have the point where they should be, finger and toe nails are probably the remnants of claws that other animals and mammals still have!

They are a modified claw. Claws can be a hindrance performing some of the tasks primates do, so most of them have developed flat nails instead.

So it's easier to scratch someones eyes out, and get rid of that nasty little itch.
