"Twin" Village

The village of Kodinki in India is home to more than 200 sets of twins, and the number is increasing.
The village's population is only 15,000 people.

"Based on scientific facts, we feel something in the environment is causing this. It could be something in the water," said a local doctor, M.K. Sribiju.

"All the world over the cause of twins is mainly because of drugs. Everywhere in the Western world, people are exposed to fertility drugs, their food habits, they consume more dairy products. Everywhere the age of marriage is increasing. There are late marriages predisposed to occurrence of twins," he said.

However in Kodinji, most marriages are between people aged 18 to 20 years old.

"All the factors leading to the occurrence of twinning world wide, we cannot see it here. There is something unknown that is causing this phenomenon," he said.

The locals also believe it has to do with the water. Kodinji is surrounded by water in the fields and during the monsoon season it becomes inaccessible from heavy rains.
