Ants started farming fungi 66 million years ago. If the 66 million-year mark sounds familiar, it is because that was when an unsuspecting massive asteroid raced toward Earth and crashed into modern-day Mexico. This happened for a few million years in the wild. But later, ants domesticated fungi varieties and brought them back to their nests. This continues to this day, where leaf-cutter ants carry leaves to their nest to feed the fungi. When a daughter queen is ready to leave the nest, she also takes a bit of fungus in her mouth to continue farming in her new colony.by AmeyS@97 on TwosAnts started farming fungi 66 million years ago.
