Wooden Ere Ibeji figures representing twins. Yorubas have the highest twinning rate in the world.
The Yoruba present the highest dizygotic twinning rate in the world (4.4% of all maternities) They manifest at 45–50 twin sets (or 90–100 twins) per 1,000 live births, possibly because of high consumption of a specific type of yam containing a natural phytoestrogen which may stimulate the ovaries to release an egg from each side. Twins are very important for the Yoruba and they usually tend to give special names to each twin. The first of the twins to be born is traditionally named Taiyewo or Tayewo, which means 'the first to taste the world', or the 'slave to the second twin', this is often shortened to Taiwo, Taiye or Taye. Kehinde is the name of the last born twin. Kehinde is sometimes also referred to as Kehindegbegbon which is short for; Omo kehin de gba egbonand means, 'the child that came behind gets the rights of the elder'
