Diving Discovery Bajau Tribe in Indonesia Uncover New Genetic Adaptation to Underwater Life

Residents of Indonesia have long marveled at the astonishing abilities of the Bajau tribe, who have mastered the art of diving unlike any other humans. This ancient tribe, living off the coasts of Indonesia for over a millennium, has adapted genetically to excel in an amphibious way of life, largely spent in the sea. Researchers have recently unveiled the remarkable genetic mutation, known as the ‘sea nomad gene,’ that enables the Bajau people to dive extensively and thrive underwater.

According to studies conducted at Cambridge University, the Bajau tribe’s exceptional lung capacities, swimming prowess, and ability to free dive up to 230 feet are not solely due to skills learned over generations. The key factor behind their underwater endurance lies in their enlarged spleens, a genetic advantage that heightens their diving abilities. This unique adaptation triggers the human dive response, enhancing oxygen levels in the bloodstream by up to nine percent when submerged in water.

Dr. Melissa Ilardo emphasized the significance of the Bajau tribe’s thyroid hormone levels in relation to their spleen size, drawing parallels to deep-diving seals that possess abnormally large spleens. The Bajau people’s lifestyle revolves around the sea, with some individuals claiming to stay underwater for as long as 13 minutes. However, their traditional ways are now facing threats, including challenges in gaining citizenship and depleting food sources due to commercial fishing activities.

Despite the obstacles they face, the Bajau tribe continues to embody a unique connection to the sea, showcasing an unparalleled resilience and genetic adaptation that sets them apart from any other human population. Their extraordinary abilities in diving and underwater survival serve as a testament to the power of genetic evolution over centuries, offering a glimpse into the intricate relationship between humans and the natural world. Through their ongoing struggles and triumphs, the Bajau people exemplify the enduring spirit of adaptation and survival in the face of environmental changes and societal challenges.
