"The Formation of Vegetable Mould Through the Action of Worms" by Charles Darwin is a scientific book published in 1881. Darwin's final scientific work explores how earthworms transform soil through their daily activities. He demonstrates that these humble creatures, working gradually over long periods, create profound changes to the earth's surface. Through decades of observation and experiments—from his own garden to ancient ruins at Stonehenge—Darwin reveals how millions of worms per acre continuously reshape the ground beneath our feet, making the invisible visible.
