There are important things you should know about the fingerprints. Probably you know that criminals burn fingerprints to avoid being identified. Or you have heard that every person has a unique pattern. However, in this post, we share useful facts about fingerprints that are not known by most people.
What you should know about fingerprints
Not all people have fingerprints
There are certain genetic conditions, which prevent the formation of identifying one’s fingerprints. These conditions include adermatoglyphia, Naegeli-Franceschetti-jadassohn syndrome, and DPR. Although lack of the prints is not perfect, it is not a huge disorder that is associated with such disorders.
Fingerprinting is not foolproof
It is quite comforting to believe that criminal investigators can find the bad guy in case he forgets putting on gloves before committing a crime. You should note that this particular method of identification is not foolproof. In fact, there are no minimum comparison points. Also, human beings are fallible. Studies show that there is a 0.1 percent false positive rate. This means that there are about 70,000 false IDs.
Interesting origin history
Have you ever wondered why human beings have these particular markings? It all starts with their development in the uterus. It is believed that fingerprints glow at a unique rate from the remaining part of the skin at the hands. Thus, it pulls at the dermis and these results in very strange patterns, which make the identities very distinct. Ideally, several layers of the skin get bent and then twisted together to result in a unique and strange marker.
Many animals have them
It is not only human beings that have this particular unique marker. Remember that human beings are in the group of gorillas, koalas, and chimpanzees. According to science, it may as a result of spending time on trees. The truth is that koala’s prints are quite similar to the human beings. In fact, even experts have a difficult time differentiating them from others.
Fingerprints can be erased
Some professions or conditions make people lose their markers. For instance, certain chemotherapy drugs such as capecitabine can cause erasure or reduction of the markings. Also, jobs such as repetitive bricklaying can wear fingerprints away.
Removing fingerprints is not an easy task as it may appear. In the last few decades, fingerprinting was quite common that criminals had to avoid being identified through them. Thus, they had to burn them off using an acid or even cutting them off.…
