‘Worms have played a more important part in the history of the world than most persons would at first suppose.” Charles Darwin
Have you ever felt the texture of the best friend of a gardener? I DARE YOU!
To uncover how they play this role Darwin threw himself at his worm studies with as much childlike enthusiasm as he could muster; he was, until the day he died, eager to learn and full of ideas to help him do so. He set about a series of experiments to test the senses of worms; he had his children play instruments to them, his wife (who was trained by Chopin) played the piano to an audience of worms, light was shone on them, and they were vibrated, blown on and tickled. His conclusions:
‘Worms do not possess any sense of hearing. They took not the least notice of the shrill notes from a metal whistle, which was repeatedly sounded near them: nor did they of the deepest and loudest tones of a bassoon. They were indifferent to shouts, if care was taken that breath did not strike them. When placed on a table close to the keys of a piano, which was played as loudly as possible, they remained perfectly quiet’
