An Evolutionary Perspective of Software Development
Memes, originally coined by Richard Dawkins in "The Selfish Gene" are cultural genes; ideas that propagate among people and affect the way we think and act. Julian Everett has suggested that we can look at software development practices, ideas, and culture as a collection of memes. By doing so, our understanding of what works and why can be turned on its head.
