Identical twins originate from one particular egg that's been fertilized by one sperm. For unknown reasons, the fertilized egg splits into 2 or more embryos during the first stage of development. Some identical twins share the same placenta. However, they generally grow within separate amniotic sacs inside the uterus. In rare cases, identical twins share one amniotic sac (monoamniotic). People in the Elizabethan era didn't like to take baths. The common belief was that a bath can make you sick.
