FBI has found that no two individuals have:
any common minutiae
more than 8 common minutiae
common minutiae except identical twins

at least 8 or more matching minutiae
at least 12 or more matching minutiae
at least 50 or more matching minutiae
at least 20 or more matching minutiae

What is the advantage to humans for having fingerprint ridges?
Ridges make skin thicker and more difficult for insects and parasites to penetrate.
Ridges make it easier to grip objects and pick them up.
Ridges allow nerves to be closer to the outside environment for us to better feel things.
Ridges provide no advantage and are complete random.
