Dawkins argues that altruism doesn’t exist in nature, so it must be an idea that was invented at some point, and then spread in human culture. Some examples of memes include the idea of God, a catchy tune or jingle, a memorable image, or-importantly-the idea of altruism. Since each brain has a limited capacity for memory, memes essentially compete to be remembered, in a new form of evolution: cultural evolution. According to Dawkins, a meme is a replicator. The scientist will likely also talk about the idea with their peers, and maybe mention it in their papers, meaning more people will learn about the idea and store a “copy” of the idea in their brains. If the scientist likes the idea, they’ll talk about it in their lectures, and their students will learn about the idea as well. For example, a scientist might learn about an idea from a paper. Dawkins uses the term 'selfish gene' as a way of expressing the gene-centred view of evolution (as opposed to the views focused on the organism and. Williams's Adaptation and Natural Selection (1966). Richard Dawkins coins the word “meme” by adapting it from the Greek word mimeme, which means “imitate.” He thinks memes jump from brain to brain, by being copied into different people’s minds. The Selfish Gene is a 1976 book on evolution by the biologist Richard Dawkins, in which the author builds upon the principal theory of George C. A meme is a catchy idea that circulates in a culture.
