Fingerprints

In class on Tuesday, we discussed the importance of fingerprints. Since Wilson has the towns fingerprints on file, but doesn’t always refer back to them, it seems as if fingerprints weren’t as important as they are today.
As we discussed in class, every person has a different set of fingerprints. Their absolutely unique to its owner. So I did some research and found that two centuries ago, the fingerprint was not so important, because it was only discovered in the late 19th century that all fingerprints are different from one another. In 1880, an English scientist named Henry Faulds stated that the fingerprints of people did not change throughout their lives, and that suspects could be convicted by the fingerprints they left on surfaces, such as glass. In 1884, for the first time, a murder was solved by means of identifying fingerprints. Since then, fingerprints have become an important method of identification. Before the 19th century, however, people most likely had never thought that the wavy shapes on their fingertips had any meaning or considered them of importance.

    I used to be a biology major and we studied fingerprints in my Genetics class. One interesting theory that we learned as a reasoning for fingerprints is that they are leftover from when we evolved from being tree climbers. It is theorized that they used to be “grips” for keeping a firm hold onto the trees. Not only do primates have fingerprints as well, but so do koalas.

    we have unique internal ear designs as well. from a side view, you can be identified by your ear. It’s the next step in biometrics actually…
