Question: What was the name of the book darwin published?

Disambiguated questions and answers:
context: Darwin published his theory of evolution with compelling evidence in his 1859 book "On the Origin of Species". By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact. However, many favoured competing explanations which gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

context: Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations, and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. In 1871 he examined human evolution and sexual selection in "The Descent of Man, and Selection in Relation to Sex", followed by "The Expression of the Emotions in Man and Animals" (1872). His research on plants was published in a series of books, and in his final book, "The Formation of Vegetable Mould, through the Actions of Worms" (1881), he examined earthworms and their effect on soil.
