Let us begin with the language Darwin uses when he first sketches his theory at the beginning of the fourth chapter of the Origin: Can it, then, be thought improbable, seeing that variations useful to man have undoubtedly occurred, that other variations useful in some way to each being in the great and complex battle of life, should sometimes occur in the course of thousands of generations? If such do occur, can we doubt remembering that many more individuals are born than can possibly survive that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind?

Charles Darwin English scientist. Generally regarded as the most prominent of the nineteenth-century evolutionary theorists, Charles Darwin is primarily known for his On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, the publication of which in ushered in a new era of naturalistic thinking that was to influence not only the field of biological science, but also the disciplines of art, literature, philosophy, and theology.
In the work Darwin identified genetic mutation and natural selection as the mechanisms that controlled the development of species. His theory introduced the concept of ever-present competitive struggle in nature, thereby decentering the commonly held Romantic view of nature as a benign, even benevolent force, and pushed the role of God to the margins of human existence on earth.
Although one of many contributors to the field of evolutionary biology, Darwin is commonly associated with the popular acceptance of evolutionary theory, and his Origin is believed to be the impetus for an intellectual revolution as philosophers, social scientists, and writers began to explore the far-reaching implications of his naturalistic theory, which posed a serious challenge to the orthodoxy of Victorian religion, science, and philosophy.
His grandfather was the noted physician, botanist, and poet, Erasmus Darwin, who had been a popularizer of evolutionary biology in the late eighteenth century.
The journey lasted five years, taking Darwin to the Andes, as well as to Tierra del Fuego at the southern tip of the continent, and to the Galapagos archipelago. By this time, and largely in response to geological and biological evidence he had accumulated in South America, Darwin was formulating his theory of natural selection, although it was not to appear in print untilwith the publication of On the Origin of Species.
The work stirred instant controversy and made Darwin one of the most recognizable figures in Victorian England. Over the years, in response to strident criticism, Darwin prepared five revised editions of the book, and meanwhile published several monographs on botany and zoology.
Inhis Descent of Man, and Selection in Relation to Sex, another work tied to his theory of evolutionary biology appeared. Descent likewise caused an uproar among critics, but Darwin, highly reserved for most of his life, responded in part by resuming his studies of plants and animals outside a purely evolutionary context.
His last book published during his lifetime, The Formation of Vegetable Mould, through the Action of Worms, with Observations on Their Habitsappeared in the year before his death at the age of seventy-three.
Major Works Darwin wrote several books on a range of scientific topics, including botany, zoology, and geology. Among his earliest works, the Journal of Researches is as much a travelogue as a book on science, and captures his responses to the beauty of the Brazilian rainforest and cultural observations of the natives at Tierra del Fuego.
In the Origin Darwin argued that environmental factors acting upon random genetic mutations produce changes in species by allowing those individuals better adapted for survival in a given environment to thrive and reproduce in greater numbers than other members of the same species.
This process he termed "descent with modification," which, he maintained, produced large-scale changes in species only over vast periods of time. The revolutionary implications of the theory were further elucidated in Descent, wherein Darwin applied the principles of evolution specifically to human beings and thereby explicitly contradicted widely-held religious explanations of human origins by observing that they shared a common origin with apes and monkeys, and ultimately with even the simplest forms of life.
Critical Reception By introducing the element of chance into his model of evolution, and thereby supplanting divine intervention as the primary force in the creation of life, Darwin had posed a direct challenge to the prevailing religious and moral constructs of his time and provoked a furious response from many quarters.
Darwin engaged these oppositions by refining his theory over time, until it gradually gained scientific and popular acceptance.For an introduction to an evolutionary psychological approach to studying animal cognition, see Sara Shettleworth’s Cognition, Evolution, and Behavior.

The process of rejection is commonly considered to have begun with Descartes and to have culminated in Darwins theory of evolution by natural selection.
