Doctors are studying a unique village in the southern Indian state of Kerela that has over 500 twins in just 2,000 households, the local Hindi daily Danik Bhaskar said Thursday.
While twin births in the village has been observed for at least three generations, the number of twins born in village Kodinhi is increasing every year, said the report.
Dr. Krishan Sribhuj, who has been studying the village for the last two years, said while number of registered twins stood at 500,the actual number of twins exceeded 600.
The doctor has ruled out environmental causes or pollution as a factor, saying all twins are healthy and without any disorders.
He suspected that the phenomenon is related with the feeding habits of the villagers, who have 45 twins for every 1,000 people, six times higher than average.
In 2008 alone, 30 twins were born in the village.
