Andean Villagers' Genes Show Millennia of Arsenic Exposure
Original: genetics
New research indicates that villagers in the Andes drank arsenic-laced water for thousands of years, and their DNA appears to reflect adaptations to this chronic exposure. The findings offer a striking example of how long-term environmental pressures can leave measurable traces in the human genome.
Why now: Fresh coverage of a genetics study highlighting human adaptation to arsenic is drawing attention.
