English: The Formation of Vegetable Mould through the Action of Worms (sometimes shortened to Worms) is an 1881 book by Charles Darwin on earthworms. It was his last scientific book, and was published shortly before his death (see Darwin from Insectivorous Plants to Worms). Exploring earthworm behavior and ecology, it continued the theme common throughout his work that gradual changes over long periods of time can lead to large and sometimes surprising consequences.
