“Older plants send out volatiles to younger plants that contain within them information about chemical responses to predators. A bean plant, being fed upon by a spider mite, can analyze from its saliva just what type of spider mite is feeding on it. It then will craft a specific pheromone, releasing it from its leaf stomata as a volatile chemical into the air. That pheromone will call to the plant the >exact predator that feeds on that particular spider mite. Older plants store this information as a kind of cultural learning that is then passed on to younger generations. Old growth plants are repositories of the acquired learning of the species. Cultural learning and transmission is, in reality, common throughout the Gaian system. Chimpanzees teach their young to collect termites with a stick, and how to make the stick.

Which is harder than it sounds; the stick must be shaped exactly. Scientists who tried to do so failed… continuously.”
