"This is a subject of but small importance; and I know not whether it will interest any readers, but it has interested me."-C. D. Quick... what was Darwin's most popular book? If you answered The Origin of Species, you were wrong. It was his last book, published the year before he died, The Formation of Vegetable Mould Through the Action of Worms With Observation of Their Habits (illustrations [first presented 1 Nov. 1837, as noted in the record of the Royal Geological Society]). Darwin noted when he was beginning his career that worms churned up soil, causing heavier objects to sink slowly in the soil. He noted that all soil had passed through the alimentary duct of worms. It started off a fashion of cultivating worms by gardeners that continues to the present day. -We recently learned that we owe an element of our unique cerebral cortex, or pallium to our marine worm ancestors. (In amphibians, the cerebrum includes archipallium, paleopallium and some of the basal nuclei. Reptiles first developed a neopallium, which continued to develop in the brains of more recent species to become the neocortex of mammals." [&, ultimately, you and you and we]) [more inside]

Earthworms are social animals after all, and now they're communicating. Time to run for the hills!

Charlie Darwin joins the fray. Yes, The formation of vegetable mould, through the action of worms, with observations on their habits is there.
