The quote p21: Reference 26 : Decades ago, evolutionary biologist George Christopher Williams began questioning whether natural selection had such power - Adaption and Natural Selection, by George C. Williams, 1966, p. 54
Fact : In 1966,Williams’ book Adaptation and Natural Selection set a new standard for evolutionary studies and focused research at the level of the gene [9]. The influence of this book would be difficult to overestimate. The trend towards the molecularization of biology had been underway for
more than a decade before the book was published, but Williams’ sweeping critique of group selection theory marked the beginning of a new age of genic selection. The basic idea of the age of genic selection was simply that natural selection is always, or for the most part, selection for and against single genes [10]. Of course, this position was not universally accepted. Ernst Mayr had maintained since the early 1960s that although natural selection had an effect on gene frequencies, it was not necessarily the case that natural selection is selection for or against particular genes.
Over the past ten years there has been a reassessment of the models and data that led to the earlier categorical rejection of group selection. There has also been a wider application of multilevel selection theory. Indeed, many of the strongest critics of group selection have come to embrace multilevel analysis. Williams has come to accept the existence of group selection and its role in evolutionary processes, particularly with regard to the evolution of sex. Indeed, in the preface to the 1996 reissue of Adaptation and Natural Selection he wrote: ‘Even without its producing biotic adaptation, group selection can still have an important role in the evolution of the Earth’s biota’ (Source : http://www.nbb.cornell.edu/wkoenig/wicker/NB4340/Borrello%202005.pdf )
The quote :
Myth 1. Mutations provide the raw materials needed to create new species. The teaching of macroevolution is built on the claim that mutations —random changes in the genetic code of plants and animals—can produce not only new species but also entirely new families of plants and animals."
