The History of Creation, Vol. 2 (of 2) / Or the Development of the Earth and its Inhabitants by the Action of Natural Causes

The text offers a popular exposition of evolutionary theory, sketching a monophyletic hypothesis for humanity and situating life within successive geological periods. It examines the fossil record and stratigraphy, explains preservation biases, gaps, and the limits of paleontological evidence, and argues for reading pedigrees from comparative anatomy and embryology. It surveys the origin and diversification of protists, plants, and animals, tracing likely descent from single-celled ancestors through major groups to vertebrates and mammals, and addresses classification, phylogenetic trees, life-cycle alternations, and the combined roles of paleontology, development, and morphology in reconstructing organic history.
