Fingerprints start forming during the fetal stage of development, specifically around the 10th week of pregnancy. By the 12th to 18th month after birth, most babies have developed clear and identifiable fingerprints.
While the initial development of fingerprints begins in the womb, they continue to refine and become more distinct during the first year or two of life.
Here's a timeline of fingerprint development:
- 10th week of pregnancy: Fingerprints begin to form.
- 12-18 months old: Fingerprints are typically fully developed and identifiable.
