However, the theory of progressive evolution by selection through natural challenges and sexual preference across geological epochs as argued in the On the Origin of Species (1859)4 was still to be considered by all reasonable, educated persons as an astounding, unprecedented achievement. In historical terms, a dividing line has been reinforced between the pre and post-Darwinian worlds, emphasising the supposed difference between biological guesswork and precise judgement. A sense of caution and inquiry as well as lively internal debate on implications was not a block to overriding optimism. To the Neo-Darwinians, Darwin formed the inexorable foundation of a grand positivist tradition that included genetics, evolutionary psychology, cross-disciplinary science, political and religious reform, and natural history. To discard the supposed inherent, historically consistent validity of Darwin 's "branching"development of species, the factual existence of genetic predisposition to phenotypical traits, and the creation of different species and genera by natural selection by sex and natural challenges over vast, climatic geological epochs5 was seemingly to discard confidence in biology, science, or even the entire history of liberal Western society as a whole according to Larry Witham6. This marks the general Neo-Darwinian position on Darwinian as inescapably positivist, in that a sense of societal improvement through “science” is inexorable from it. Dawkins made the
