A gripping investigation that opens fresh perspectives on biology and anthropology 'At the cutting edge of contemporary thought' GUARDIAN 'A thoroughly enjoyable read' SUNDAY TELEGRAPH While living among Peruvian Indians, anthropologist Jeremy Narby became intrigued by their claim that their phenomenal knowledge of plants and biochemistry was communicated to them directly while under the influence of hallucinogens. Despite his initial scepticism, Narby found himself engaged in an increasingly obsessive personal quest. The evidence he collected - on subjects as diverse as molecular biology, shamanism, neurology and ancient mythology - led inexorably to the conclusion that the Indians' claims were literally true: to a consciousness prepared with drugs, specific biochemical knowledge could indeed be directly transmitted through DNA itself. A gripping investigation that opens fresh perspectives on biology, anthropology and the limits of rationalism, The Cosmic Serpent is new science of the most exhilarating kind.
