The social effects of evolutionary thought have been considerable. As the scientific explanation of life's diversity has developed, it has often displaced alternative, sometimes very widely held, explanations. Because the theory of evolution includes an explanation of humanity's origins, it has had a profound impact on human societies. Some have vigorously denied acceptance of the scientific explanation due to its perceived religious implications (e.g. its implied rejection of the special creation of humans presumably described in the Bible). This has led to a vigorous conflict between creation and evolution in public education, primarily in the United States.
The theory of evolution by natural selection has also been adopted as a foundation for various ethical and social systems, such as social Darwinism, an idea that preceded the publication of The Origin of Species, popular in the 19th century, which holds that "the survival of the fittest" (a phrase coined in 1851 by Herbert Spencer, [1] 8 years before Darwin published his theory of evolution) explains and justifies differences in wealth and success among societies and people. A similar interpretation was one created by Darwin's cousin, Francis Galton, known as eugenics, which claimed that human civilization was subverting natural selection by allowing the less bright and less healthy to survive and out-breed the smarter and more healthy.
Later advocates of this theory suggested radical and often coercive social measures in an attempt to "correct" this imbalance. Thomas Huxley spent much time demonstrating through a series of thought experiments that it would not only be immoral, but impossible. [2] Stephen Jay Gould and others have argued that social Darwinism is based on misconceptions of evolutionary theory, and many ethicists regard it as a case of the is-ought problem. After the atrocities of the Holocaust became linked with eugenics, it greatly fell out of favor with public and scientific opinion, though it was never universally accepted by either, and at no point in Nazi literature is Charles Darwin or the scientific theory of evolution mentioned. [3] [ better source needed ]
In his book The End of Faith , Sam Harris argues that Nazism was largely a continuation of Christian anti-Semitism. Jim Walker compiled a list of 129 quotes from Mein Kampf in which Hitler described himself as a Christian, or mentioned God, Jesus or a biblical passage. [4] Some[ who? ] argue that six million of the people killed during the Holocaust were killed because of their religion (Judaism) not their race, "strength," or any reason with an obvious link to the mechanism of Darwinian evolution. Hitler often used Christian beliefs like, "Jews killed Jesus," to justify his anti-Semitism. [5]
The notion that humans share ancestors with other animals has also affected how some people view the relationship between humans and other species. Many proponents of animal rights hold that if animals and humans are of the same nature, then rights cannot be distinct to humans.
Charles Darwin, in fact, considered "sympathy" to be one of the most important moral virtues — and that it was, indeed, a product of natural selection and a trait beneficial to social animals (including humans). Darwin further argued that the most "sympathetic" societies would consequently be the most "successful." He also stated that our sympathy should be extended to "all sentient beings":
As man advances in civilization, and small tribes are united into larger communities, the simplest reason would tell each individual that he ought to extend his social instincts and sympathies to all the members of the same nation, though personally unknown to him. This point being once reached, there is only an artificial barrier to prevent his sympathies extending to the men of all nations and races. If, indeed, such men are separated from him by great differences in appearance or habits, experience unfortunately shows us how long it is, before we look at them as our fellow-creatures. ... This virtue, one of the noblest with which man is endowed, seems to arise incidentally from our sympathies becoming more tender and more widely diffused, until they are extended to all sentient beings. As soon as this virtue is honored and practiced by some few men, it spreads through instruction and example to the young, and eventually becomes incorporated in public opinion.
— Charles Darwin; The Descent of Man, 1871
Before Darwin's argument and presentation of the evidence for evolution, Western religions generally discounted or condemned any claims that diversity of life is the result of an evolutionary process, as did most scientists in the English scientific establishment. However, evolution was accepted by some religious groups such as the Unitarian church and the liberal Anglican theologians who went on to publish Essays and Reviews , as well as by many scientists in France and Scotland and some in England, notably Robert Edmund Grant. Literal or authoritative interpretations of Scripture hold that a supreme being directly created humans and other animals as separate Created kinds , which to some means species. This view is commonly referred to as creationism. From the 1920s to the present in the US, there has been a strong religious backlash to the teaching of evolution theory, particularly by conservative evangelicals. They have expressed concerns about the effects of the teaching of evolution on society and their faith (see Creation–evolution controversy).
In response to the wide scientific acceptance of the theory of evolution, many religions have formally or informally synthesized the scientific and religious viewpoints. Several important 20th century scientists (Fisher, Dobzhansky) whose work confirmed Darwin's theory, were also Christians who saw no incompatibility between their experimental and theoretical confirmations of evolution and their faith. Some religions have adopted a theistic evolution viewpoint, where God provides a divine spark that ignited the process of evolution and (or) where God has guided evolution in one way or another.
The Roman Catholic Church, beginning in 1950 with Pope Pius XII's encyclical Humani Generis, took up a neutral position with regard to evolution. "The Church does not forbid that...research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter." [6]
In an October 22, 1996, address to the Pontifical Academy of Science, Pope John Paul II updated the Church's position, recognizing that Evolution is "more than a hypothesis" - "In his encyclical Humani Generis, my predecessor Pius XII has already affirmed that there is no conflict between evolution and the doctrine of the faith regarding man and his vocation... Today, more than a half-century after the appearance of that encyclical, some new findings lead us toward the recognition of evolution as more than an hypothesis. In fact it is remarkable that this theory has had progressively greater influence on the spirit of researchers, following a series of discoveries in different scholarly disciplines." [7]
In 1861 Karl Marx wrote to his friend Ferdinand Lassalle, "Darwin’s work is most important and suits my purpose in that it provides a basis in natural science for the historical class struggle. ... Despite all shortcomings, it is here that, for the first time, 'teleology' in natural science is not only dealt a mortal blow but its rational meaning is empirically explained." [19]
Most later Marxists agreed with this view, but some – particularly those in the early Soviet Union – believed that evolutionary theory conflicted with their economic and social ideals. As a result, they came to support Lamarckism instead – the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring. This led to the practice of Lysenkoism, which caused agricultural problems.
In his book, Mutual Aid: A Factor of Evolution , anarcho-communist Peter Kropotkin argued that co-operation and mutual aid are as important in the evolution of the species as competition and mutual strife, if not more so.
On the contemporary moderate left, some authors such as Peter Singer (in his book, A Darwinian Left ) support Darwinism but reach different political and economic lessons than more conservative observers. Richard Dawkins' book, The Selfish Gene , has a chapter, "Nice guys finish first," that attempts to explain the role of altruism and cooperation in evolution and how social animals not only cannot survive without such traits, but how evolution will create them. Dawkins explains that when an animal sacrifices itself or uses its resources for the survival of other members of the same species, its genes, present in the other animals, survive. For example, if a mother dies to save three of its pups, one and a half copies (on average) of its genes will survive, because there is a 50% chance of a particular gene being present in its offspring. Dawkins also made a documentary of the same name. [20] According to the documentary, Dawkins added that chapter as a way of overcoming modern day misinterpretations of the concept of survival of the fittest. Left-wing transhumanists see technology as a means to overcome inequalities that stem from biology. New left feminist Shulamith Firestone saw technological control over reproduction as essential for gender equality.[ citation needed ] More recently the Laboria Cuboniks collective has articulated an antinaturalist politics that seeks to overcome essentialist categories through technological empowerment.

"Social Darwinism" is a derogatory term associated with the 19th century Malthusian theory developed by Whig philosopher Herbert Spencer. It is associated with evolutionary theory but now widely regarded as unwarranted. Social Darwinism was later expanded by others into ideas about "survival of the fittest" in commerce and human societies as a whole, and led to claims that social inequality, sexism, racism and imperialism were justified. [22] However, these ideas contradict Darwin's own views, and contemporary scientists and philosophers consider these ideas to be neither mandated by evolutionary theory nor supported by data. [23] [24] [25]
Social Darwinism is further linked with nationalism and imperialism. [26] During the age of New Imperialism, the concepts of evolution justified the exploitation of "lesser breeds without the law" by "superior races." [26] To elitists, strong nations were composed of white people who were successful at expanding their empires, and as such, these strong nations would survive in the struggle for dominance. [26] With this attitude, Europeans, except for Christian missionaries, seldom adopted the customs and languages of local people under their empires. [26] Christian missionaries, on the other hand, were the very first individuals to meet new peoples and develop writing systems for local inhabitants' languages that lacked one. [26] Being critics of Social Darwinism, they ardently opposed slavery and provided an education and religious instruction to the new peoples they interacted with since they felt that this was their duty as Christians. [26]
Creationism is the religious belief that nature, and aspects such as the universe, Earth, life, and humans, originated with supernatural acts of divine creation. In its broadest sense, creationism includes a continuum of religious views, which vary in their acceptance or rejection of scientific explanations such as evolution that describe the origin and development of natural phenomena.
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. Also called Darwinian theory, it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance after Darwin published On the Origin of Species in 1859, including concepts which predated Darwin's theories. English biologist Thomas Henry Huxley coined the term Darwinism in April 1860.
Richard Dawkins is a British evolutionary biologist, zoologist, science communicator and author. He is an emeritus fellow of New College, Oxford, and was Professor for Public Understanding of Science in the University of Oxford from 1995 to 2008. His book The Selfish Gene (1976) popularised the gene-centred view of evolution and coined the word meme. Dawkins has won several academic and writing awards.
Social Darwinism is the study and implementation of various pseudoscientific theories and societal practices that purport to apply biological concepts of natural selection and survival of the fittest to sociology, economics and politics. Social Darwinists believe that the strong should see their wealth and power increase, while the weak should see their wealth and power decrease. Social Darwinist definitions of the strong and the weak vary, and differ on the precise mechanisms that reward strength and punish weakness. Many such views stress competition between individuals in laissez-faire capitalism, while others, emphasizing struggle between national or racial groups, support eugenics, racism, imperialism and/or fascism.
Theistic evolution, alternatively called evolutionary creationism, is a view that God acts and creates through laws of nature. Here, God is taken as the primary cause while natural causes are secondary, positing that the concept of God and religious beliefs are compatible with the findings of modern science, including evolution. Theistic evolution is not in itself a scientific theory, but includes a range of views about how science relates to religious beliefs and the extent to which God intervenes. It rejects the strict creationist doctrines of special creation, but can include beliefs such as creation of the human soul. Modern theistic evolution accepts the general scientific consensus on the age of the Earth, the age of the universe, the Big Bang, the origin of the Solar System, the origin of life, and evolution.
Recurring cultural, political, and theological rejection of evolution by religious groups exists regarding the origins of the Earth, of humanity, and of other life. In accordance with creationism, species were once widely believed to be fixed products of divine creation, but since the mid-19th century, evolution by natural selection has been established by the scientific community as an empirical scientific fact.
The history of creationism relates to the history of thought based on the premise that the natural universe had a beginning, and came into being supernaturally. The term creationism in its broad sense covers a wide range of views and interpretations, and was not in common use before the late 19th century. Throughout recorded history, many people have viewed the universe as a created entity. Many ancient historical accounts from around the world refer to or imply a creation of the earth and universe. Although specific historical understandings of creationism have used varying degrees of empirical, spiritual and/or philosophical investigations, they are all based on the view that the universe was created. The Genesis creation narrative has provided a basic framework for Jewish and Christian epistemological understandings of how the universe came into being – through the divine intervention of the god, Yahweh. Historically, literal interpretations of this narrative were more dominant than allegorical ones.
The status of creation and evolution in public education has been the subject of substantial debate and conflict in legal, political, and religious circles. Globally, there are a wide variety of views on the topic. Most western countries have legislation that mandates only evolutionary biology is to be taught in the appropriate scientific syllabuses.
Michael Escott Ruse was a British-born Canadian philosopher of science who specialised in the philosophy of biology and worked on the relationship between science and religion, the creation–evolution controversy, and the demarcation problem within science. Ruse began his career teaching at The University of Guelph and spent many years at Florida State University.
The Catholic Church holds no official position on the theory of creation or evolution, leaving the specifics of either theistic evolution or literal creationism to the individual within certain parameters established by the Church. According to the Catechism of the Catholic Church, any believer may accept either literal or special creation within the period of an actual six-day, twenty-four-hour period, or they may accept the belief that the earth evolved over time under the guidance of God. Catholicism holds that God initiated and continued the process of his creation, that Adam and Eve were real people, and that all humans, whether specially created or evolved, have and have always had specially created souls for each individual.
Jewish views on evolution includes a continuum of views about the theory of evolution, experimental evolution, the origin of life, the age of the universe, and theistic evolution. Today, many Jewish people accept the theory of evolution and do not see it as incompatible with traditional Judaism, reflecting the emphasis of prominent rabbis such as the Vilna Gaon and Maimonides on the ethical rather than factual significance of scripture.
Islamic views on evolution are diverse, ranging from theistic evolution to Old Earth creationism. Some Muslims around the world believe "humans and other living things have evolved over time", yet some others believe they have "always existed in present form". Some Muslims believe that the processes of life on Earth started from one single point of species with a mixture of water and a viscous clay-like substance. Muslim thinkers have proposed and accepted elements of the theory of evolution, some holding the belief of the supremacy of God in the process. Some scholars suggested that both narratives of creation and of evolution, as understood by modern science, may be believed by modern Muslims as addressing two different kinds of truth, the revealed and the empirical. Others argue that faith and science can be integrated and complement each other.
Polygenism is a theory of human origins which posits the view that the human races are of different origins (polygenesis). This view is opposite to the idea of monogenism, which posits a single origin of humanity. Modern scientific views find little merit in any polygenic model due to an increased understanding of speciation in a human context, with the monogenic "Out of Africa" hypothesis and its variants being the most widely accepted models for human origins. Polygenism has historically been heavily used in service of white supremacist ideas and practices, denying a common origin between European and non-European peoples. It can be distinguished between Biblical polygenism, describing a Pre-Adamite or Co-Adamite origin of certain races in the context of the Genesis narrative of Adam and Eve, and scientific polygenism, attempting to find a taxonomic basis for ideas of racial science.
A Civic Biology: Presented in Problems was a biology textbook written by George William Hunter, published in 1914. It is the book which the state of Tennessee required high school teachers to use in 1925 and is best known for its section about evolution that was ruled by a local court to be in violation of the state Butler Act. It was for teaching from this textbook that John T. Scopes was brought to trial in Dayton, Tennessee in the Scopes "Monkey" Trial. The views espoused in the book about evolution, race, and eugenics were common to American Progressives.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution initially met opposition from scientists with different theories, but eventually came to receive near-universal acceptance in the scientific community. The observation of evolutionary processes occurring has been uncontroversial among mainstream biologists since the 1940s.
From Darwin to Hitler: Evolutionary Ethics, Eugenics, and Racism in Germany is a 2004 book by Richard Weikart, a historian at California State University, Stanislaus, and a senior fellow for the Center for Science and Culture of the creationist Discovery Institute. The work is controversial. Graeme Gooday, John M. Lynch, Kenneth G. Wilson, and Constance K. Barsky wrote that "numerous reviews have accused Weikart of selectively viewing his rich primary material, ignoring political, social, psychological, and economic factors" that helped shape Nazi eugenics and racism.
Why Darwin Matters: The Case Against Intelligent Design is a 2006 book by Michael Shermer, an author, publisher, and historian of science. Shermer examines the theory of evolution and the arguments presented against it. He demonstrates that the theory is very robust and is based on a convergence of evidence from a number of different branches of science. The attacks against it are, for the most part, very simplistic and easily demolished. He discusses how evolution and other branches of science can coexist with religious beliefs. He describes how he and Darwin both started out as creationists and how their thinking changed over time. He examines current attitudes towards evolution and science in general. He finds that in many cases the problem people have is not with the facts about evolution but with their ideas of what it implies.
The Genius of Charles Darwin is a three-part television documentary, written and presented by evolutionary biologist Richard Dawkins.
Non-overlapping magisteria (NOMA) is the view, advocated by paleontologist Stephen Jay Gould, that science and religion each represent different areas of inquiry, fact vs. values, so there is a difference between the "nets" over which they have "a legitimate magisterium, or domain of teaching authority", and the two domains do not overlap. He suggests, with examples, that "NOMA enjoys strong and fully explicit support, even from the primary cultural stereotypes of hard-line traditionalism" and that it is "a sound position of general consensus, established by long struggle among people of goodwill in both magisteria." Some have criticized the idea or suggested limitations to it, and there continues to be disagreement over where the boundaries between the two magisteria should be.
Although biological evolution has been vocally opposed by some religious groups, many other groups accept the scientific position, sometimes with additions to allow for theological considerations. The positions of such groups are described by terms including "theistic evolution", "theistic evolutionism" or "evolutionary creation". Of all the religious groups included on the chart, Buddhists are the most accepting of evolution. Theistic evolutionists believe that there is a God, that God is the creator of the material universe and all life within, and that biological evolution is a natural process within that creation. Evolution, according to this view, is simply a tool that God employed to develop human life. According to the American Scientific Affiliation, a Christian organization of scientists:
A theory of theistic evolution (TE) — also called evolutionary creation — proposes that God's method of creation was to cleverly design a universe in which everything would naturally evolve. Usually the "evolution" in "theistic evolution" means Total Evolution — astronomical evolution and geological evolution plus chemical evolution and biological evolution — but it can refer only to biological evolution.
The most extreme ideological expression of nationalism and imperialism was Social Darwinism. In the popular mind, the concepts of evolution justified the exploitation by the 'superior races' of 'lesser breeds without the law.' This language of race and conflict, of superior and inferior people, had wide currency in the Western nations. Social Darwinists vigorously advocated empires, saying that strong nations—by definition, those that were successful at expanding industry and empire—would survive and others would not. To these elitists, all white peoples were more fit than nonwhites to prevail in the struggle for dominance. Even among Europeans, some nations were deemed more fit than others for the competition. Usually, Social Darwinists thought their own nation the best, an attitude that sparked their competitive enthusiasm. ...In the nineteenth century, in contrast to the seventeenth and eighteenth centuries, Europeans, except for missionaries, rarely adopted the customs or learned the languages of local people. They had little sense that other cultures and other peoples deserved respect. Many Westerners believed that it was their Christian duty to set an example and to educate others. Missionaries were the first to meet and learn about many peoples and the first to develop writing for those without a written language. Christian missionaries were ardently opposed to slavery....
