Twin fetuses learn how to be social in the womb

Twin fetuses learn how to be social in the womb: Researchers have been studying pregnancies involving twins. Psychologist Umberto Castiello explained that newborns appear to be already 'wired' to interact socially with other humans soon after birth, and previous research has demonstrated that within only a few hours after birth babies can imitate gestures of people around them and make other social interactions. Studying twins in the womb made it possible to see investigate the pre-wired hypothesis and see if socialization was already apparent while still in the womb.
