Coastal Adaptations

The discussion explores the genetic adaptations of coastal populations, particularly focusing on the haenyeo, a group of female divers from Jeju Island. These remarkable women, averaging around 70 years old, dive in frigid waters without wetsuits and continue to do so throughout pregnancy, showcasing extraordinary resilience and potential implications for cardiovascular health. The conversation challenges conventional views of human evolution, emphasizing the significant role of aquatic environments in shaping our species.
