Why Do We Have Lines On Our Palms?

The video explains the formation and function of palmar flexion creases, which develop around the 12th week of gestation. These creases help the skin of the palm to stretch and fold, aiding in various hand movements. Scientists have classified these creases into three main types: distal palmar, proximal palmar, and thanar creases. Besides their functional role, these creases can indicate certain congenital disorders. The video also discusses the cultural practice of palmistry, which lacks scientific support and is considered a pseudoscience. Different cultures interpret palm lines differently, and the video advises skepticism towards palmistry without empirical evidence.
