Why do people have fingerprints?
Fingerprints do not help primates grip, as previously thought, scientists have discovered. They actually reduce the friction needed to hold onto flat surfaces. Now Dr Roland Ennos and his team at The University of Manchester are trying to find out: why do we have them?
Dr Ennos, at the University’s Faculty of Life Sciences, said: “I have been thinking about this for years and, having played around with it for a bit, realised that skin is rubbery so the ridges in fingerprints might actually reduce grip.
