terrence suggested that certain chemicals produced in abundance in various hallucinogenic plants and fungi, such as dimethyltryptamine and psilocybin may act as pheromones produced by one species (the vegetal) waiting for absorption by various others (for example, early primates or hominids). In this way a kind of ecological pheromonal system may be at work among species and ecosystems that have coevolved closely for long stretches of time....i suggest you read "food of the gods" by terrence mckenna....its all about psilocybin and evolution and MANY other thing realted to that.. i love it...i own the book.. as well as mushroom wisdom by Martin W ball PH.D, that book i own aswell and its really good
