The following is a summary of the Origin taking each chapter in turn. (The boundary between the two parts of the book is not always as clear as implied here, as chapter nine is closely related to ten.) Chapter fourteen is a recapitulation and conclusion. These last four chapters deal with geology, geography, taxonomy, morphology and embryology. These chapters lay down what requires the explanation provided in the first four chapters. The second part of the Origin,chapters ten to thirteen, attempts to cover what exactly natural selection is competent to explain about the history and diversity of life. Chapters five to nine deal with a range of issues and difficulties which impinge on this competence. Of these chapters the first three establish its existence and the fourth makes the case for its ability to explain common ancestry. The first part, chapters one to nine, establishes natural selection as a true cause.

The book is called Origin of species because it answered the question, what is the origin or source of new species? Where did they come from? He argued that they were not specially created from nothing but descended from earlier species. His second argument was that the process he called 'natural selection' was responsible for how species change and become adapted. In other words, he wanted to convince his readers that evolution is a fact. His first was that the different species of living things on Earth evolved by natural means from earlier ancestors. In it, he offered two separate but intertwined arguments. Darwin's Origin of species, first edition (1859) An introduction by Gordon Chancellor and John van WyheĬharles Darwin's Origin of species of 1859 is one of the most important books ever published.
