An abnormal number of twins was found on the Philippine island of Alabat. This was reported by The Mirror.
In total, 78 pairs of heterozygous and 22 pairs of monozygous twins live on Alabat. The youngest twins on the island are four-month-old Can and John, and the oldest are Eudosia and Antononia Meras, who are over 80 years old.
In 2015, 12 pairs of twins were born on the island.
Alabat is also home to a couple of Siamese twins - ten-year-old Joy and Joyce Magsino. Their grandmother also had a twin. The girls have fused heads at birth, and surgeons refuse to separate them, as it is very likely that they will not survive the operation.
Filipino doctors and scientists believe that the anomaly is explained not by genetic reasons, but by some features of the environment. Now they are carefully studying the island's drinking water.
At the moment, only one place is known in which more twins live than in Alabat. This is the village of Kodinhi in southwestern India, home to about 350 twins. Scientists also cannot explain such an anomaly.
