Major topics in science typically include a zone of consensus among the experts, based on past progress, and a zone of current controversy still being thrashed out. The topic of group selection is unusual in the degree of ignorance among professional evolutionists who are experts on other topics, but whose ideas about group selection remain sadly out of date. Their ignorance interferes with the peer review process when they are called upon to review articles on their area of expertise that are written from a multilevel perspective. David Sloan Wilson and Omar Eldakar review eight criticisms that no one should be making about group selection, based on a commentary published in the academic journal Evolution in 2011.
