YVAN RIOUX was a keen naturalist as a boy, taught by Christian Brothers and Franciscans. He studied biology at Montreal University, but it left him cold as it didn't touch anything that was alive. Working for ten years as a biodynamic farmer in Quebec, however, he encountered living ecosystems. Later, in Montreal, he taught on the relationship between human physiology and nature. In 1992 he moved to England with his two boys and joined a family of two girls and their mother, Gabriel Millar, who became his muse. Retiring ten years ago, he decided to write about his knowledge gained from 25 years' of teaching experience, culminating in the publication of The Mystery of Emerging Form.
