On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) [3] is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology. It was published on 24 November 1859. [4]
Darwin then wrote an abstract, titled On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, which he published in 1859. [1] The first two chapters were published in 1868 as The Variation of Animals and Plants Under Domestication.
The article was the first announcement of the Darwin–Wallace theory of evolution by natural selection; and appeared in print on 20 August 1858. The presentation of the papers spurred Darwin to write a condensed "abstract" of his "big book", Natural Selection. This was published in November 1859 as On the Origin of Species.
Natural selection is a cornerstone of modern biology. The concept, published by Darwin and Alfred Russel Wallace in a joint presentation of papers in 1858, was elaborated in Darwin's influential 1859 book On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. He described natural ...
Natural selection: The survival and reproductive rate of a species depends on the adaptability of the species to their environment. This process is called natural selection . [ 15 ] Some species with certain traits in a population have higher survival and reproductive rate than others ( fitness ), and they pass on these genetic features to ...
The papers entitled respectively On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection, incorporated Wallace's pages; and extracts from Darwin's 1844 Essay and his 1857 letter to Gray. At the meeting the Secretary read the papers out, before going on to six other papers, and ...
To answer the question, Darwin had introduced in the Origin the theory of sexual selection, which outlined how different characteristics could be selected for if they conveyed a reproductive advantage to the individual. In this theory, male animals in particular showed heritable features acquired by sexual selection, such as "weapons" with ...
In On the Origin of Species (1859), Darwin interpreted biological evolution in terms of natural selection, but was perplexed by the clustering of organisms into species. [7] Chapter 6 of Darwin's book is entitled "Difficulties of the Theory". In discussing these "difficulties" he noted
