Anyone catch the PBS Documentary based on book "Botany of Desire" or the City Arts and Lectures (San Francisco) interview with Michael Pollen about the book of same name ?
Interesting concept that certain successful plants adapt to the selection pressures applied by humans-- that humans are one part of the natural environment of plants and human behavior can be "exploited" by plants to increase the chance that a given plant species will flourish or disperse worldwide. The central theme of the book is that certain plants have been very successful because they indulge particular human desires (for esthetic beauty, for security, for intoxication, for sweetness, etc.) and often human behaviors are driven by the propagation requirements of these certain plants.
