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 Allopatric speciation definition yahoo dating 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 speciationand sympatric speciation.

The mere fact that punk eek is wholly founded on Ernst Mayr's allopatric speciation a concept alluded to by Darwin himself belies the fact that it is not the antithesis of "gradualism" but a complement to it as one Gould would argue the primary one of several paths possible "Allopatric speciation definition yahoo dating" the diversification of a lineage of organisms.

For example, morphological similarity superficially suggests widespread species, high gene flow, few barriers to dispersal, a dearth of allopatric speciation and, therefore, greater probability that other modes of speciation have contributed significantly to marine biodiversity 2.
