Fingerprints are an odd phenomenon, made stranger by their utter uniqueness. According to Live Science, which of these is a possible reason that we have fingerprints?

It's not 100% clear to scientists why we have fingerprints, but two prevailing theories are that they help us feel things better or that they improve grip. Either way they've evolved as humans have relied more and more on their hands to use tools. It's not clear why each one is completely unique, but it comes in "handy" when identifying criminals.
