The Formation of Vegetable Mould Through the Action of Worms

"...I was led to keep in my study during many months worms in pots filled with earth, I became interested in them, and wished to learn how far they acted consciously..."

- Charles Darwin, The Formation of Vegetable Mould Through the Action of Worms (1881)

The Formation of Vegetable Mould Through the Action of Worms, with Observations on their Habits (1881) includes original illustrations and highlights the extensive research and study of Darwin's landmark discoveries on soil formation, later termed soil bioturbation, as well as his fascination with earthworm behavior. In his last scientific book, published shortly before his death, Darwin documents with zest the earthworm's sexual passions and social interactions, as well as their significant contributions to the earth's ecosystem.

This in-depth research is a must-read for lovers of ecology and biology.
