"It may be doubted whether there are many other animals which have played so important a part in the history of the world, as have these lowly organised creatures."

This was a quote by the father of the theory of evolution, Charles Darwin, when describing the earthworm in his book, On the Formation of Mould.

Following the discovery of worms that could help aid toxic land clean up, we decided to investigate these overlooked creatures further. We talked to experts in this field Professor Mark Hodson and Professor John Morgan on their current research and how the Earthworm has benefited humanity.
