A Mechanico-Physiological Theory of Organic Evolution

''A Mechanico-Physiological Theory of Organic Evolution'' is a scientific work by Carl Nägeli, written in the late 19th century. The book presents a mechanistic and physiological perspective on biological evolution, introducing Nägeli's micellar theory, which suggests that organisms are composed of micelles that evolve through spontaneous generation and adaptation. It critiques Darwinian natural selection, proposing an intrinsic guiding force within organisms that leads to increased complexity. Nägeli's integration of biology, chemistry, and physics offers a unique view of organic evolution, though it remains less recognized compared to his contemporaries.
