Crime Scene Investigation: Pizza
If we choose to investigate this pizza to figure out which person is responsible for this sensory theft of our taste buds, we have a fingerprint on it. Fingerprints are impressions left by the ridges of human skin.
Because every finger has a unique pattern, fingerprints have become one of the most reliable ways to identify people. The use of fingerprints to solve crimes began in Argentina in the 1890s, and in 1910 it became a common practice in the United States.
