5. 05

   Types of Patterns: There are three main types of fingerprint patterns: loops, whorls, and arches. Loops are the most common, followed by whorls, with arches being the rarest.

6. 06

   Formation: Fingerprints form in the womb around the 10th week of pregnancy. The patterns are influenced by genetic and environmental factors.

Fingerprints in Forensics

Fingerprints play a crucial role in forensic science, helping solve crimes and identify individuals.

7. 07

   First Criminal Case: The first criminal case solved using fingerprints was in Argentina in 1892. A woman named Francisca Rojas was convicted of murdering her children based on fingerprint evidence.

8. 08

   AFIS: The Automated Fingerprint Identification System (AFIS) was introduced in the 1980s. It allows law enforcement to quickly compare fingerprints against a database.

9. 09

   Latent Prints: Latent fingerprints are invisible to the naked eye. They are made visible using powders, chemicals, or alternate light sources.

Fingerprints in Technology

Modern technology has harnessed the power of fingerprints for various applications.
