Darwin Descendant's Voice Plants' First Choice

A study by the Royal Horticultural Society shows that plants grow more when talked to by women than by men—and grow best when talked to by a descendant of Charles Darwin.

Each plant “listened” to a different recording through the headphones of an MP3 player attached to its pot at root level.

The plants were kept in the same greenhouse and measured before, during and after the experiment. Control plants were not exposed to the sound of a human voice.

The plant that grew the most had been listening to Sarah Darwin, great-great-granddaughter of Charles, reading his revolutionary work. Her plant grew 1.6cm (almost two thirds of an inch) higher than the most successful of the two control plants. [Link]
