Why do people have finger and toe nails? |
[Edit] 
Toe and finger nails
They are 'tools' that we have adapted from our ancestors that had claws; a part of evolution and natural selection.
They also serve to protect our fingers, which are very dense with nerves. This helps keep our fingers more sensitive and dexterous which is important for all the amazing things that we can do with our hands.
