Fascinating read
Richard L. Doty is director of the University of Pennsylvania's Smell  and Taste Center. His awards include the US National Institutes of  Health's James A. Shannon award (1996), and the Association for  Chemoreception Sciences' Max Mozell award for outstanding achievement in  the chemical senses (2005). This essay is based on his book, The  Great Pheromone Myth (Johns Hopkins University Press)
Richard Doty states:
"All in all, it looks as if "pheromonology" has become a modern-day  phrenology, providing simple but false explanations for most chemically  mediated social behaviours and endocrine responses, satisfying only  those who seek simple answers to complex phenomena. Perhaps once the  idea that mammals have pheromones is dispelled, we can work towards an  appreciation of the real role chemicals play in their lives".
