Technical Tuesday Fingerprints
Have you ever wondered why humans have
fingerprints? Why isn’t finger skin as smooth as other parts of the body? There
must be a reason. Right?
Well, it is debated. Some experts
believe fingerprints give us a better grip – like tire treads. But some studies
showed that those little ridges actually make it more difficult to hold
onto smooth surfaces (due to reduced skin contact). Some say fingerprints help
with water wicking: allowing water to
flow off our fingertips more effectively. Still others say fingerprints allow
the skin to stretch more easily, thus preventing abrasions like blisters. And
all ballet dancers have an intimate knowledge of blisters!
Here is one thing the experts do know about fingerprints: No two
people have the same fingerprints – even identical twins! Now there’s something
to think about…
