Group selection accustomed to group selection thinking that he did not realize his views "contravened orthodox Darwinian theory". The ethologist Niko Tinbergen praised Lorenz for his interest in the survival value of behavior, and naturalists enjoyed Lorenz's writings for the same reason. In 1962, group selection was used as a popular explanation for adaptation by the zoologist V. C. Wynne-Edwards. In 1976, Richard Dawkins wrote a well-known book on the importance of evolution at the level of the gene or the individual, "The Selfish Gene". From the mid 1960s, evolutionary biologists argued that natural selection acted primarily at the level of the
The Selfish Gene unit of heredity." However, he continues in a later chapter: Dawkins' later formulation is in his book "The Extended Phenotype" (1982), where the process of selection is taken to involve every possible phenotypical effect of a gene. Stephen Jay Gould finds Dawkins' position tries to have it both ways: The view of "The Selfish Gene" is that selection based upon groups and populations is rare compared to selection on individuals. Although supported by Dawkins and by many others, this claim continues to be disputed. While naïve versions of group selectionism have been disproved, more sophisticated formulations make accurate predictions in
