Doctors are trying to unravel the mystery of an Indian village boasting 250 sets of twins born to just 2,000 families.
The phenomenon has seen almost six times as many twins born than the global average in the remote village of Kodinhi, in Kerala.
In 2008 alone 15 pairs of twins were born in the village out of 300 healthy deliveries and this year is expected to top that number.
In the last five years alone up to 60 pairs of twins have been born, with the rate of twins increasing year-on-year.
Local doctor and twin enthusiast Dr Krishnan Sribiju has been studying the medical marvel of Kodinhi for the past two years. Although 250 sets of twins have been officially registered in the village Dr Sribiju believes the real number to be far higher. "In my medical opinion there are around 300 to 350 twins within the village boundaries of Kodinhi," he said
According to villagers, the twin phenomenon only started occurring three generations ago. Dr Sribiju said: "To the best of my knowledge this medical marvel began somewhere between 60 to 70 years ago"
"Without access to detailed biochemical analysis equipment I cannot say for certain what the reason for the twinning is, but I feel that it is something to do with what the villagers eat and drink"
