Define meme

Richard Dawkins used the term 'meme' to refer to any cultural entity that an observer might consider a replicator. He hypothesised that one could view many cultural entities as replicators, and pointed to melodies, fashions and learned skills as examples. Memes generally replicate through exposure to humans, who have evolved as efficient copiers of information and behaviour. Because humans do not always copy memes perfectly, and because they may refine, combine or otherwise modify them with other memes to create new memes, they can change over time. Dawkins likened the process by which memes survive and change through the evolution of culture to the natural selection of genes in biological evolution.


Dawkins defined the meme as a unit of cultural transmission, or a unit of imitation, but later definitions would vary. The lack of a consistent, rigorous, and precise understanding of what typically makes up one unit of cultural transmission remains a problem in debates about memetics.[12] In contrast, the concept of genetics gained concrete evidence with the discovery of the biological functions of DNA. In the context of the exact sciences, memetics suffers in comparison because, unlike the idea of genes, memes do not necessarily have or need a concrete medium in order to transfer
