Researchers have identified the oldest known evidence of genetic adaptation to the Indian Monsoon cycles in 8,000-year-old remains excavated from the Malabar Coast. The study, appearing in Nature Communications, highlights specific pathogen-resistance genes that allowed early coastal populations to thrive in high-humidity, disease-prone environments.
The genomic data suggests that these early inhabitants had already developed a metabolic resilience to seasonal dietary shifts. This research provides a critical link in the anthropological history of the Indian Peninsula, showing that the ancestors of modern South Indian populations had established a stable genetic footprint long before the arrival of later migratory groups.
