A comprehensive genomic study published in Cell Reports on April 2, 2026, has identified a previously unknown 'ghost' population that inhabited the islands of the South China Sea during the early Holocene. By analyzing ancient DNA from 8,000-year-old skeletal remains found in a submerged sea cave, researchers detected a genetic signature that does not match any known modern or ancient mainland population.
This paleogenomic research suggests that this group were highly specialized maritime explorers who possessed advanced seafaring capabilities long before the Austronesian expansion. The study also identifies genetic adaptations for deep-sea diving and high-salt diets, indicating a culture that was almost entirely dependent on marine resources. This discovery adds a new chapter to the anthropological history of Southeast Asia, revealing a complex web of lost maritime civilizations.
