In a major update to the history of the Fertile Crescent, a study published in Nature Genetics has identified a distinct genetic pulse entering Eastern Anatolia approximately 12,000 years ago. By analyzing the remains found near Lake Van, researchers have mapped a 'ghost' population from the Caucasus that contributed significantly to the gene pool of the region's first sedentary hunter-gatherers.
This genomic study highlights that the transition to agriculture was not just a cultural shift but was driven by a complex intermingling of diverse lineages. The findings suggest that these Caucasus migrants brought specific genetic adaptations for high-altitude resilience, which may have allowed early communities to exploit the diverse microclimates of the Anatolian plateau more effectively during the warming Holocene.
