In an unprecedented series of global field experiments launched ten years ago at the Max Planck Institute for Biology Tübingen, an international research team has tracked real-time evolution in the plant Arabidopsis thaliana. Across 30 locations worldwide — from the Alps to the Negev Desert — researchers sowed the plants, monitored their development, and analyzed genetic changes over several years. Their findings reveal that many populations managed to adapt to local climates within just a few years, while others went extinct, demonstrating how genetic diversity is essential to population survival.
