Everyone is special; everyone is different. ‘You can change your world by changing your words… Remember, death and life are in the power of the tongue’. Joel Osteen. As we all know forensic scientists have used fingerprints in criminal investigations as a means of identification for centuries.
Fingerprint identification is one of the most important criminal investigation tools due to two features: their persistence and their uniqueness. A person’s fingerprints do not change over time. Because each person’s fingerprints are unique, and not even identical twins—who share the same DNA—have identical fingerprints, this also shows that fingerprints are not completely controlled by genetics
Many modes of identification systems have come into existence later as fingerprint, iris scan, skin color, signature verification, voice recognition, and face recognition. However, do you know that the tongue is unique to every person with respect to its shape, length width and thickness. Since it is an internal organ, it can be easily exposed for inspection and the exposed surface carries the required information. The surface and shape remain constant. The external surroundings protect the tongue, and so the external factors do not seem to have important impact.
It is also a reliable proof of life. Shapes of the tongue are elliptical; hammer; rectangular; square; acute triangle; obtuse triangle and round. (1) It seems that the quotes the tongue has NO bones, but it is strong enough to break a heart will turn into fact as the tongue can be a strong proof of identity. No two tongues are similar.
