Title: Charles Darwins work on the humble Earthworn,we can blame them for aching limbs!

Darwin’s work on worms during his latter years also reflected his interest in processes that, acting slowly and gradually over time, have a huge impact. The habits of earthworms do just this. As Darwin wrote ‘worms have played a more important part in the history of the world than most persons would at first suppose’.

Darwin measured how much material they would ingest (eat), and how much they egested (pooped). He estimated how many worms there were on average in a given amount of soil, showing that all the soil in Britain ‘has passed many times through and will again pass many times through, the intestinal canals of worms’.

The rate at which worms process the soil can explain how ancient ruins are buried: Darwin calculated that worms push up eight tonnes of earth through the casts at the entrances of their burrows. He even carried out experiments to show this could happen within a human lifetime, he laid a stone in his garden, which was not to be disturbed, and measured the rate at which the earth was raised around it.Darwin showed for the first time that worms increase the fertility of soils by aerating and mixing rotting material, this allows better root growth and water retention. By doing so he revolutionised compost heaps everywhere!
