Nice answer Tony. The article does not answer the question.
We have finger nails because we are mammals. All mammals developed claws or nails as a survival trait. They are used as weapons, or to help climb surfaces, etc. They also provide extra support when holding or grasping things.
For humans we do not use our nails as much as we are tool users and most of the things we could use our nails for, we have tools (cleaning teeth, digging, climbing). Sometimes my own nails come in handly to pick up things (small pins) or to open packages without using a knife....
