This book, published in 1881, was the result of many years of experimentation and observation by Darwin in the open-air laboratory of his garden at Down House in Kent. As he wrote in his introduction, the subject of soil disturbance by worms 'may appear an insignificant one, but we shall see that it possesses some interest'. He goes on to demonstrate the immensity - in size and over time - of the accumulated tiny movements of soil by earthworms, and their vital role in aerating the soil and breaking down vegetable material to keep the topsoil, the growing medium for all plant life and thus…mehr

Produktbeschreibung
This book, published in 1881, was the result of many years of experimentation and observation by Darwin in the open-air laboratory of his garden at Down House in Kent. As he wrote in his introduction, the subject of soil disturbance by worms 'may appear an insignificant one, but we shall see that it possesses some interest'. He goes on to demonstrate the immensity - in size and over time - of the accumulated tiny movements of soil by earthworms, and their vital role in aerating the soil and breaking down vegetable material to keep the topsoil, the growing medium for all plant life and thus vital to human existence, fertile and healthy. At a time when there is huge interest in growing food organically and without using artificial fertilisers, Darwin's insights are as important, and his descriptions of his experiments as fascinating, as they were in the late nineteenth century.
Autorenporträt
Charles Robert Darwin, (12 February 1809 - 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge (Christ's College) encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author. Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations, and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.
