The book - -  consolidates a revolution in thinking that is contained in Forsdyke's earlier publications, for example his 2001 book The Origin of Species Revisited. Like many revolutions Forsdyke's is catalyzed by a renewed look at the past. Specifically, he has revived a number of questions about evolutionary process which were raised in the 19th Century by William Bateson - who was Gregory Bateson's father and the inventor of the word genetics - and by the essayist Samuel Butler - -  . These questions deal with the fundamental issue of the origin of species and how they diverge, but because they point away from natural selection as the only and total explanation they have by and large been ignored by the mainstream of evolutionary theorizing. - -  Forsdyke goes far to show how processes which either can directly be called schismogenesis, or which might be analytically related to schismogenesis-processes which cannot be understood without very sophisticated molecular genetic analysis, and yet may have been anticipated conceptually by Butler among others-might be the answer to hybrid sterility and thus to some of the problems relating to the origins of species that niggled at William Bateson in his later years. By treasuring his conceptual exceptions, WB recognized that there was a residue problem that had not been fully explained by Darwin or by Mendel. Forsdyke has directly contributed to addressing that residue and explaining it in a 21st Century way.
