Richard Dawkins in the context of Science book

In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two end populations in the series which are too distantly related to interbreed, though there is a potential gene flow between linked neighbouring populations. Such non-breeding, though genetically connected, end populations may co-exist in the same region (sympatry) thus closing a ring. The German term Rassenkreis, meaning "circle of races", is also used.

Ring species represent speciation and have been cited as evidence of evolution. They illustrate what happens over time as populations genetically diverge, specifically because they represent, in living populations, what normally happens over time between long-deceased ancestor populations and living populations, in which the intermediates have become extinct. The evolutionary biologist Richard Dawkins remarks that ring species "are only showing us in the spatial dimension something that must always happen in the time dimension".

In genetics, the phenotype (from Ancient Greek φαίνω (phaínō) 'to appear, show' and τύπος (túpos) 'mark, type') is the set of observable characteristics or traits of an organism. The term covers all traits of an organism other than its genome, however transitory: the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological properties whether reversible or irreversible, and all its behavior, from a peacock's display to the phone number you half remember. An organism's phenotype results from two basic factors: the expression of an organism's unique profile of genes (its genotype) and the influence of environmental factors experienced by that same organism which influence the variable expression of said genes, and thereby shape the resulting profile of defining traits. Since the developmental process is a complex interplay of gene-environment, gene-gene interactions, there is a high degree of phenotypic variation in a given population that extends beyond mere genotypic variation.

A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and again in his 1982 book The Extended Phenotype suggested that one can regard bird nests and other built structures such as caddisfly larva cases and beaver dams as "extended phenotypes".

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was a British and American author and journalist. He authored 18 books on faith, religion, culture, politics, and literature.

Hitchens was born and educated in Britain, graduating in 1970 from the University of Oxford with a degree in philosophy, politics, and economics. In the early 1980s, he emigrated to the United States and wrote for The Nation and Vanity Fair. Known as one of the "Four Horsemen" of New Atheism (along with Richard Dawkins, Sam Harris, and Daniel Dennett), he gained prominence as a columnist and speaker. His epistemological razor, which states that "what can be asserted without evidence can also be dismissed without evidence", is still of mark in philosophy and law. Hitchens's political views evolved greatly throughout his life. Originally describing himself as a democratic socialist, he was a member of various socialist organisations in his early life, including the Trotskyist International Socialists.

The Extended Phenotype is a 1982 book by the evolutionary biologist Richard Dawkins, in which the author introduced a biological concept of the same name. The book's main idea is that phenotype should not be limited to biological processes such as protein biosynthesis or tissue growth, but extended to include all effects that a gene has on its environment, inside or outside the body of the individual organism.

Dawkins considers The Extended Phenotype to be a sequel to The Selfish Gene (1976) aimed at professional biologists, and as his principal contribution to evolutionary theory.

Sir Ronald Aylmer Fisher FRS (17 February 1890 – 29 July 1962) was a British polymath who was active as a mathematician, statistician, biologist, geneticist, and academic. He has been described as "a genius who almost single-handedly created the foundations for modern statistical science" and "the single most important figure in 20th century statistics". In genetics, Fisher was the one to most comprehensively combine the ideas of Gregor Mendel and Charles Darwin, as his work used mathematics to combine Mendelian genetics and natural selection; this contributed to the revival of Darwinism in the early 20th-century revision of the theory of evolution known as the modern synthesis. For his contributions to biology, Richard Dawkins declared Fisher to be the greatest of Darwin's successors. He is also considered one of the founding fathers of Neo-Darwinism. According to statistician Jeffrey T. Leek, Fisher is the most influential scientist of all time on the basis of the number of citations of his contributions.

From 1919, he worked at the Rothamsted Experimental Station for 14 years; there, he analyzed its immense body of data from crop experiments since the 1840s, and developed the analysis of variance (ANOVA). He established his reputation there in the following years as a biostatistician. Fisher also made fundamental contributions to multivariate statistics.

William Donald Hamilton FRS (1 August 1936 – 7 March 2000) was a British evolutionary biologist, recognised as one of the most significant evolutionary theorists of the 20th century. Hamilton became known for his theoretical work expounding a rigorous genetic basis for the existence of altruism, an insight that was a key part of the development of the gene-centered view of evolution. He is considered one of the forerunners of sociobiology. Hamilton published important work on sex ratios and the evolution of sex. From 1984 to his death in 2000, he was a Royal Society Research Professor at Oxford University.

Richard Dawkins has written that Hamilton was "the greatest Darwinian of my lifetime".

Group selection is a proposed mechanism of evolution in which natural selection acts at the level of the group, instead of at the level of the individual or gene.

Early authors such as V. C. Wynne-Edwards and Konrad Lorenz argued that the behaviour of animals could affect their survival and reproduction as groups, speaking for instance of actions for the good of the species. In the 1930s, Ronald Fisher and J. B. S. Haldane proposed the concept of kin selection, a form of biological altruism from the gene-centered view of evolution, arguing that animals should sacrifice for their relatives, and thereby implying that they should not sacrifice for non-relatives. From the mid-1960s, evolutionary biologists such as John Maynard Smith, W. D. Hamilton, George C. Williams, and Richard Dawkins argued that natural selection acts primarily at the level of the gene. They argued on the basis of mathematical models that individuals would not altruistically sacrifice fitness for the sake of a group unless it would ultimately increase the likelihood of an individual passing on their genes. A consensus emerged that group selection did not occur, including in special situations such as the haplodiploid social insects like honeybees (in the Hymenoptera), where kin selection explains the behaviour of non-reproductives equally well, since the only way for them to reproduce their genes is via kin.

New Atheism is a 21st-century movement promoted by some atheist academics, writers, scientists, and philosophers opposed to superstition, religion, and irrationalism. New Atheists advocate the antitheist view that the various forms of theism should be examined, countered by rational arguments and criticised, especially when they exert strong influence on the broader society, such as in government, education, and politics.

Major figures of New Atheism include Richard Dawkins, Daniel Dennett, Christopher Hitchens, and Sam Harris, collectively referred to as the "Four Horsemen" of the movement. Proponents of the New Atheist movement have experienced some controversy and criticisms from academics and other atheists.

Samuel Benjamin Harris (born April 9, 1967) is an American neuroscientist, philosopher, author, and podcast host. His work touches on a range of topics, including rationality, religion, ethics, free will, determinism, neuroscience, meditation, psychedelics, philosophy of mind, politics, terrorism, and artificial intelligence. Harris came to prominence for his criticism of religion, and he is known as one of the "Four Horsemen" of New Atheism, along with Richard Dawkins, Christopher Hitchens, and Daniel Dennett.

Harris's first book, The End of Faith (2004), won the PEN/Martha Albrand Award for First Nonfiction and remained on The New York Times Best Seller list for 33 weeks. He has since written six additional books: Letter to a Christian Nation (2006); The Moral Landscape: How Science Can Determine Human Values (2010); the essay Lying (2011); the short book Free Will (2012); Waking Up: A Guide to Spirituality Without Religion (2014); and (with British writer Maajid Nawaz) Islam and the Future of Tolerance: A Dialogue (2015). His work has been translated into over 20 languages.

An Internet meme, or meme (/miːm/, MEEM), is a cultural item (such as an idea, behavior, or style) that spreads across the Internet, primarily through social media platforms. Internet memes manifest in a variety of formats, including images, videos, GIFs, and other viral content. Key characteristics of memes include their tendency to be parodied, their use of intertextuality, their viral dissemination, and their continual evolution. The term meme was originally introduced by Richard Dawkins in his 1976 book The Selfish Gene to describe the concept of cultural transmission.

The term Internet meme was coined by Mike Godwin in 1993 in reference to the way memes proliferated through early online communities, including message boards, Usenet groups, and email. The emergence of social media platforms such as YouTube, Twitter, Facebook, and Instagram further diversified memes and accelerated their spread. Newer meme genres include "dank" and surrealist memes, as well as short-form videos popularized by platforms like Vine and TikTok. Newer internet memes are often defined as brain rot.

Memetics is a theory of the evolution of culture based on Darwinian principles with the meme as the unit of culture. The term "meme" was coined by biologist Richard Dawkins in his 1976 book The Selfish Gene, to illustrate the principle that he later called "Universal Darwinism". All evolutionary processes depend on information being copied, varied, and selected, a process also known as variation with selective retention. The conveyor of the information being copied is known as the replicator, with the gene functioning as the replicator in biological evolution. Dawkins proposed that the same process drives cultural evolution, and he called this second replicator the "meme," citing examples such as musical tunes, catchphrases, fashions, and technologies. Like genes, memes are selfish replicators and have causal efficacy; in other words, their properties influence their chances of being copied and passed on. Some succeed because they are valuable or useful to their human hosts while others are more like viruses.

Just as genes can work together to form co-adapted gene complexes, so form groups of memes acting together co-adapted meme complexes or memeplexes. Memeplexes include (among many other things) languages, traditions, scientific theories, financial institutions, and religions. Dawkins famously referred to religions as "viruses of the mind".

The Simonyi Professorship for the Public Understanding of Science is a chair at the University of Oxford. The chair was established in 1995 for the ethologist Richard Dawkins by an endowment from Charles Simonyi. The aim of the Professorship is 'to communicate science to the public without, in doing so, losing those elements of scholarship which constitute the essence of true understanding'. It is a position that had been endowed by Charles Simonyi with the express intention that the holder "be expected to make important contributions to the public understanding of some scientific field", and that its first holder should be Richard Dawkins.

The Selfish Gene is a 1976 book by ethologist Richard Dawkins that promotes the gene-centered view of evolution, as opposed to views focused on the organism and the group. The book builds upon the thesis of George C. Williams's Adaptation and Natural Selection (1966); it also popularized ideas developed during the 1960s by W. D. Hamilton and others. From the gene-centred view, it follows that the more two individuals are genetically related, the more sense (at the level of the genes) it makes for them to behave cooperatively with each other.

A lineage is expected to evolve to maximise its inclusive fitness—the number of copies of its genes passed on globally (rather than by a particular individual). As a result, populations will tend towards an evolutionarily stable strategy. The book also introduces the term meme for a unit of human cultural evolution analogous to the gene, suggesting that such "selfish" replication may also model human culture, in a different sense. Memetics has become the subject of many studies since the publication of the book. In raising awareness of Hamilton's ideas, as well as making its own valuable contributions to the field, the book has also stimulated research on human inclusive fitness.

The Blind Watchmaker: Why the Evidence of Evolution Reveals a Universe without Design is a 1986 book by Richard Dawkins, in which he presents an explanation of, and argument for, the theory of evolution by means of natural selection. He also presents arguments to refute certain criticisms made of his first book, The Selfish Gene. (Both books espouse the gene-centered view of evolution.) It was illustrated by Liz Pyle. It won the Los Angeles Times Book Prize for Current interest. A computer program of the same name was released and it was the basis for a BBC documentary. An audiobook was released, read by Dawkins and Lalla Ward.
