This is the first edition of Charles Darwin's On the Origin of Species, published on November 24, 1859 in London by John Murray. It is a seminal work in scientific literature and a landmark work in evolutionary biology. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. The starting chapters introduce the theory of natural selection, explaining why certain species thrive, while others decrease in number, how the members of nature are in competition with each other and why organisms tend to vary and change with time. Much of this work is based on experiments and observations seen within domestic animals and plants. The later chapters defend the theory of natural selection against apparent inconsistencies, why geological records are incomplete, why we find species so widespread and how sterility can be inherited when the organisation is unable to reproduce and more. The book is approachable for any audience.
Charles Darwin’s On the Origin of Species is one of the most important and yet least read scientific works in the history of science. The Annotated Origin is a facsimile of the first edition of 1859, and is accompanied by James T. Costa’s marginal annotations, drawing on his extensive experience with Darwin’s ideas in the field, lab, and classroom.
Darwin addresses some of the flaws in his theory of natural selection. He tackles two major questions: First, if species have gradually descended from other species, why do clearly defined, separate species exist, instead of numerous intermediate forms of species? Second, can natural selection really produce highly complex organs, such as the eye, from species lacking anything remotely similar to such complex organs?To answer the first question, Darwin argues that natural selection requires that intermediate varieties become extinct. Since natural selection urges species to become perfectly adapted to their environments, certain environments favor some characteristics and other environments favor others, allowing species to diverge based on their separate environments. The favored characteristics in these respective environments would become more advantageous than any intermediate characteristics, causing the intermediate species to become extinct. Darwin addresses the question of whether an intermediate species would exist in an intermediate geological area between the two different environments. He argues that intermediate environments are so geographically small that intermediate species in those areas would not be able to reproduce sufficiently to perpetuate themselves and survive and would eventually become extinct. Therefore, we only see small numbers of intermediate species in these intermediate geographical zones.Darwin is not as confident about the answer to his second question as he is about the answer to his first. He admits that it is difficult to explain how new structures, such as the wings of a bat, are created when a species descends from one that lacks such structures. He does give examples from other species, in which modifications develop from existing structures instead of sprouting anew, such as the species of flying squirrels with broad tails that allow them to parachute through the air, a tail modified from existing tails in other squirrel species. He also explains that scientists are unable to see a clear line of organ modification because of gaps in the development of these structures (for example, squirrel tails that are not yet fully adapted for flying). These gaps come about when the intermediate species have become extinct. Examples of explainable models, such as the flying squirrel's tail, can help an observer imagine the development of more complex organs, such as the wings of the bat or the eye. Over time, gradual developments of structures and nerves become more complex with modifications, until finally the most perfect eye organ develops. Darwin compares the eye to a telescope: Over time and through its development, the telescope has become more and more advanced, replacing older versions. While the mechanism of change for the telescope is technological advancement, for the eye it is natural selection.

On the Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Its full title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. For the sixth edition of 1872, the short title was changed to The Origin of Species. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. The Origin of Species attracted widespread interest upon its publication. As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. Within two decades there was widespread scientific agreement that evolution, with a branching pattern of common descent, had occurred. In the 1930s and 1940s, Darwin's concept of natural selection became central to modern evolutionary theory, and it has now become the unifying concept of the life sciences.
