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