The origin of hybrids is a consequence of a return to sympatry and the breakdown of isolating mechanisms, not the action of natural selection and drift on allopatric populations.
Similarly, studies of gametic compatibility between allopatric populations of the eastern oyster Crassostrea virginica failed to reveal strong fertilization barriers between genetic clines (north and south Florida) when sperm from each population competed to fertilize eggs from both populations (Zhang et al.

He follows with description of neural-developmental premises of evolutionary adaptation, including evolution and stress responses and behavioral adaptation to changes in environment, ontogeny, and intragenerational developmental plasticity; epigenetics of circumevolutionary phenomena and the mechanism of evolutionary change, including transgenerational developmental plasticity and the evolution of metazoans and their control system; and the origins of evolutionary novelty, evolution by loss or by reverting to ancestral characters, neural crest-determined evolutionary novelties, evolutionary convergences, species and allopatric speciation, and sympatric speciation.
Habitat alteration and climate-induced range expansions are thought to lead indirectly to increases in hybridization rates by providing areas of secondary contact among related allopatric species.
