I'm not sure, but the Yoruba people have the highest twin rate in the world, possibly because they eat a yam that contains a natural phytoestrogen.

I have a twin in real life and when people see us together, I get real sick of them asking if we are twins! How interesting! A developing fetus is called a singleton if they are alone but a multiple if there is more than one developing! Those embryos sure like multiplying! I wonder if twins are more rarer than triplets? I don't actually know, though the twin rate rose 76% between 1980 and 2009, ending up at 33.3 for every 1,000 births. Wow, do you know what caused the spike in the rate? Is it a genetic thing?
The Yoruba peoples have the highest rate of twinning in the world, 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.
