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]
Early in 1842, Darwin wrote about his ideas to Charles Lyell, who noted that his ally "denies seeing a beginning to each crop of species". [ 70 ] [ 113 ] Darwin's book The Structure and Distribution of Coral Reefs on his theory of atoll formation was published in May 1842 after more than three years of work, and he then wrote his first "pencil ...
Charles Darwin's second book of theory involved many questions of Darwin's time. It was Darwin's second book on evolutionary theory, following his 1859 work, On the Origin of Species, in which he explored the concept of natural selection and which had been met with a firestorm of controversy in reaction to Darwin's theory. A single line in this ...
Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Charles Darwin (1809–1882) used the metaphor of a "tree of life" to conceptualise his theory of evolution. In On the Origin of Species (1859) he presented an abstract diagram of a portion of a larger timetree for species of an unnamed large genus (see figure). On the horizontal base line hypothetical species within this genus are labelled A ...
Charles Darwin, author of On the Origin of Species, was a great fan of the sundew, a cousin of the venus flytrap, and is once said to have remarked: "At this present moment, I care more about ...
In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory, originally called descent with modification is known contemporarily as Darwinism or Darwinian theory.
Controversy exists as to whether Charles Darwin recognized a true geographical-based model of speciation in his publication On the Origin of Species. [5] In chapter 11, "Geographical Distribution", Darwin discusses geographic barriers to migration, stating for example that "barriers of any kind, or obstacles to free migration, are related in a close and important manner to the differences ...
