This epic work by Dankmar Bosse presents, for the first time, a comprehensive picture of the evolution of the earth and its natural kingdoms, based primarily on geology and paleontology, and with reference to the results of Rudolf Steiner’s spiritual-scientific research.“The Evolution of the Cosmos and Humanity,” chapter 4 of Rudolf Steiner’s fundamental work in 1910, An Outline of Esoteric Science, is the single most extensive expression of his suprasensory research into evolution as a whole. Nonetheless, it is an “outline,” leaving much to be explored from numerous perspectives, including the various fields of natural science, from which Steiner’s approach grew. Finally, Dankmar Bosse offers with this publication a geoscience analog to Steiner's findings. Bosse illumines numerous questions concerning the natural sciences from a new orientation―for example the relationship between humanity and the evolution of the animal kingdom; the origin of the deeper crystalline rocks; and the formation of our present-day landscapes on Earth.The Mutual Evolution of Earth and Humanity offers a fascinating exposition of the development of Earth and humanity, illustrated abundantly with color photographs and diagrams. This pioneering book will be useful to teachers, students, scientists, and anyone interested in our human relationship to the world around us.
