‘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, a 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.’
