The Bajau sea nomads are people from the Malay Archipelago (Philippines, Malaysia, and Indonesia).
Aquatic life is literally in their DNA. According to a study from the journal Cell:
They are renowned for their extraordinary abilities, diving to depths of over 70 m with nothing more than a set of weights and a pair of wooden goggles (Schagatay, 2014) and spending 60% of their daily working time underwater (Schagatay et al., 2011).
They’ve evolved to harbor extreme breath holding capabilities with up to 13 minutes underwater. For over thousands of years, the Bajau people have developed expanded spleens due to their dependency on diving underwater for food.
No one knows what originally compelled the Bajau to dive other than their need to survive and feed entire families.
Without experimentation, evolution does not exist. It is through struggle and adaptation we evolve.
