In Sense and Nonsense, Laland and Brown seek to introduce the ideas, methods, and results of the five main approaches of applying evolutionary theory to human behavior: sociobiology, human behavioral ecology, evolutionary psychology, memetics, and gene–culture evolution. Henry Plotkin (the author of Evolution in Mind: An Introduction to Evolutionary Psychology) writes, "Laland and Brown have written an up to date, blessedly balanced and refreshingly critical review of the application of evolutionary theory to the human sciences based upon the single, and surely correct, view that human behaviour is multiply determined." Laland and Brown are both researchers in the Department of Zoology at Cambridge University.
