• What is Darwin’s point about domestic breeding (for example, the breeding of pigeons and dogs)?

Breeding was a popular and familiar exercise among the farmers in the 19th century. The farmers who wanted to change the shape of the pick of the pigeon or the color of the sheep will selectively choose the sheep or the pigeon with the certain characteristics to breed. Therefore, the farmer will only breed the sheep (with white wool) and the pigeon (with a long and narrow beak) for certain duration. As a result of selective breeding, the whole flock of sheep or pigeons will have the desired characteristics. This is because the offspring will inherits some of the traits of their ...

Charles Robert Darwin was an English geologist and naturalist who lived between 1809 and 1882. He was born in a city called Shrewsbury, England in Shropshire County. Darwin was the fifth child in their family that had six children. His father, Robert Darwin, was a wealthy society doctor and also worked as a financier while their mother was known as Susannah Darwin. His grandfathers, Erasmus Darwin, from his father’s side and Josiah Wedgwood from his mother’s side were both prominent abolitionists (EGS 1). The two families were mainly Unitarian, although the Wedgwood’s family slowly started adopting Anglicanism. Darwin’s ...

Darwin established the argument on the origin of species through an analogy inspired by artificial selection or breeding and natural selection. Darwin provides that the nature’s power of selection explains the human selective practices which mount up variation in a certain direction and by so doing lead to the generation and sustenance of new and distinctive races. As such, natural selection functioning through the continuous selective action which Darwin referred to as the ‘struggle for existence’ is responsible for producing and maintaining new and distinctive species (Darwin 210). According to Darwin, nature provides successive variations while man adds increases ...

In an age of scientific advancement, it is easy to take for granted a number of widely-held facts and theories that have been largely substantiated by scientific inquiry. One of these fundamental theories is the theory of evolution-- much of science and medicine is built upon the foundation of evolutionary theory. Without an understanding of evolutionary theory, modern medicine would not have advanced to the point that it has; humanity's ability to produce vaccines and do work on genetic diseases and stem cells would be severely curtailed, if not impaired entirely. Indeed, without Darwin's introduction of evolutionary theory, humanity's understanding ...

Evolution involves the changes to the properties of an organism that go beyond the life span of a single individual and it generally occurs as a result of either natural selection, mutation, genetic drift, or by the process of gene flow or migration. The evolution theory is regarded as one of the immense intellectual revolution in the history of the human beings and it has considerably changed the world’s view of the process of evolution. Charles Darwin is credited to have played a significant role in the development of the natural selection theory that supports evolution. As a result, the natural selection theory ...
