A community on the island of Alabat in the Philippines is known for having an abundant number of twins, with one in three households having twins in the family.

Located in the centre of the Philippine island chain, a community on the island has more than 100 pairs of twins of varying categories, from identical to fraternal, and even a pair of conjoined twin girls linked at the forehead.

Currently doctors and scientists are baffled by the phenomenon occurring on an island, although other communities with abnormally high twin birth rates have been observed elsewhere.

For example, the small village of Kodinhi in Kerala, southern India had reported the presence of around 300-350 twins within the same village.

Reportedly present theories have ruled out a genetic component to the high twin birth rate on Alabat, suggesting there may be an environmental cause at work, with some inquiring whether the drinking water should be examined.

A sleepy coastal island stretched over 57 square ft. by the Quezon Mainland in the Philippines has recently grabbed the headlines for housing the most number of twins, where twins of different age groups can be found in every third house in the island.

The scientists and doctors are now baffled after discovering the most number of twins in a single island and looking ways to unravel the mystery that would prove to be a breakthrough in the field of medical science.

To date, only a single village in India was known to have housed the most number of twins. The small village of Kodinhi in Kerala in southern India had reported the presence of around 300-350 twins within the boundaries of the same village.

Local doctors have ruled out the genetic reason as to why the twinning keeps taking place, they believe that the environment has more to do with it than the genetic factors. Although some suggested that the drinking water should be studied to get a specific view of the matter, the doctors are still waiting for an indication.
