    It is theorized that we have fingernails because they are our evolved claws.  Most mammals have claws, but primates developed broad fingers so that they could climb and grasp.  They are leftover traits of evolutionary past.  Also, fingernails are a sign of health and can show if someone is malnourished.

    Fingernails serve many purposes from protecting the multitude of nerve endings in the tips of our fingers, to aiding in our ability to pick up a variety of objects.
