Nestled in Kerala’s Malappuram district, Kodinhi—dubbed India’s “Twin Village”—boasts over 400 pairs of twins among its ~2,000 families, a twin birth rate of approximately 45 per 1,000 births compared to the global average of 6 per 1,000.

The phenomenon was first noticed when eight twin pairs appeared in a single school class—prompting locals to form the Twins and Kins Association (TAKA). Since then, the community has documented dozens of new twin births annually, with some sources reporting as many as 550 twin pairs.

Despite visits from researchers at institutions like CCMB and Kerala University, studies of DNA, water, air, and dietary patterns have yet to reveal any conclusive cause. Genetic markers or environmental triggers remain speculative. Even Ayurvedic or local beliefs ranging from mineral-enriched water to divine blessings have no empirical backing.

Some scientists argue the phenomenon may simply be a statistical anomaly: in a nation with millions of villages, outliers like Kodinhi may naturally emerge without any unique biological or environmental factors.

As curiosity grows—and tourism and twin-themed local events rise—Kodinhi remains a mystery that challenges medical understanding, offering a real-life case of human duplication defying easy explanation.
