A print or mark left on a surface by a person's fingertip that can be used to identify people based on the unique pattern of spirals and lines on the fingertips. The reason our fingerprints are unique lies in a combination of genetics and environment. Here’s why: Genetics: Each person’s genetic makeup plays a role in determining their unique fingerprint patterns. However, despite decades of research, scientists still don’t fully understand how fingerprints are formed. Generally, every fingerprint is different, but there are similarities between the three middle fingers (pointer, middle, and ring fingers). Scientists call these similar patterns “pattern-blocks.” These patterns likely result from a combination of genetic factors inherited from our parents. Development in the Womb: Our fingerprints start forming while we are developing in our mother’s womb, around 10 weeks into pregnancy. By around 14 weeks, they finish forming. The ridges on our fingertips, called derm...
