Diving Adaptations

A fascinating exploration reveals that the Bajau people, known for their exceptional diving abilities, possess spleens that are significantly larger—about 50% more—than those of nearby populations. This suggests a genetic adaptation rather than just the result of diving practice. The discussion also touches on the intriguing role of thyroid hormone in red blood cell production and its potential connection to spleen function, leaving open questions about the interplay of genetics and environmental factors in these remarkable adaptations.
