print run was oversubscribed by booksellers at Murray's Autumn sale the day before. Darwin presents a theory of natural selection that is in most aspects identical to the theories now accepted by scientists. He carefully argues out this theory by presenting accumulated scientific evidence from his voyage on the Beagle in the 1830s, and from his continuing studies up to the date of publication. His studies continued with the book being revised accordingly; the most extensive revisions were the 6th and final edition. Darwin's theory of evolution by natural selection, with its tree-like model of branching common descent, has become the unifying theory of the life sciences. The theory explains the diversity of living organisms and their adaptation to the environment. It makes sense of the geologic record, biogeography, parallels in embryonic development, biological homologies, vestigiality, cladistics, phylogenetics and other fields, with unrivalled explanatory power; it has also become essential to applied sciences such as medicine and agriculture. In the preface, Fisher considers some general points, including that there must be an understanding of natural selection distinct from that of evolution, and that the then-recent advances in the field of genetics (see history of genetics) now allowed this. In the first chapter, Fisher considers the nature of inheritance, rejecting blending inheritance in favour of particulate inheritance. The second chapter introduces Fisher's fundamental theorem of natural selection. The third considers the evolution of dominance, which Fisher believed was strongly influenced by modifiers. The last five chapters (8-12) include Fisher's more idiosyncratic views on eugenics. One of the founding works of population genetics. Wilson introduced the term sociobiology as an attempt to explain the evolutionary mechanics behind social behaviors such as altruism, aggression, and nurturance. Wilson's book sparked one of the great scientific controversies in biology of the 20th century. Critically revisits Haeckel's idea that ontogeny recapitulates phylogeny. Gould presents heterochrony as a concept that allows us to describe the majority of developmental processes in evolution. This book played a significant role at the time by bringing the evolutionary biology community back to examine developmental biology, ignored for many years. A synthesis of many of the ideas of Evolutionary Psychology. This field posits that there are insights into the way that the mind works if you view our cognitive capabilities as the adaptive result of evolution. Synthesizes the work of many Evolutionary Psychologists and provides a comprehensive starting point for inquiries into
