Detailed explanation-1: -Research suggests that having a longer ring finger compared to index finger reflects greater exposure to male hormones during an individual’s time in their mother’s womb. There are differences between and within sexes in finger lengths associated with relatively more masculine versus feminine development.
Detailed explanation-2: -Men with shorter index fingers are more likely to pick fights. Women with the same hand shape are more likely to react with aggression after being provoked. Men who experience a higher surge of prenatal testosterone, and thus have longer ring fingers, tend to be risk takers.
Detailed explanation-3: -In addition to inherited physical traits such as eye color and height, you also have learned characteristics such as the language you speak or your personality. You aren’t born knowing how to ride a bicycle or tie your shoes. These skills must be taught.
