Analysis of Hybrid Zones
TL;DR: Hybrid zones are narrow regions in which genetically distinct populations meet, mate, and produce hybrids, and models of parapatric speciation, and of Wright's "shifting balance," involve the formation, move ment, and modification of hybrid zones.

Evolution, the Extended Synthesis
Massimo Pigliucci,Gerd B. Müller +1 more
TL;DR: In the six decades since the publication of Huxley's Evolution: The Modern Synthesis, the spectacular empirical advances in the biological sciences have been accompanied by equally significant developments within the core theoretical framework of the discipline.

Mechanisms of speciation a population genetic approach
TL;DR: The purpose of this review is to initiate the discussion absent in White's (234) book and much of the speciation literature and outline why it is important for population genetics and speciation theory to become integrated.
Journal ArticleDOI
Speciation by natural and sexual selection: models and experiments.
TL;DR: It is shown that the geographical context of speciation can be viewed as a form of assortative mating and this provides a framework for interpreting results from laboratory experiments, which are found to agree generally with theoretical predictions about conditions that are favorable to the evolution of prezygotic isolation.
Journal ArticleDOI
An evaluation of narrow hybrid zones in vertebrates
TL;DR: The hybrid-superiority hypothesis states that hybrids are more fit than parental phenotypes in some environments, and it is suggested that stable hybrid zones are often narrow because they tend to occur in ecotones which are themselves narrow.

Journal ArticleDOI
Speciation as a stage in evolutionary divergence.
TL;DR: A theory is suggested according to which the development of isolating mechanisms follows, rather than accompanies, that of the adaptive complexes themselves, which suggests that speciation is meant the fixation of discontinuity among organisms.

Self-incompatibility alleles in the population of oenothera organensis.
TL;DR: Computer simulation techniques are used to set up theoretical models of Oenothera organensis populations by using computer simulation techniques similar to those described in detail by Crosby and Crosby, and to follow their evolutionary history "experimentally," using a pseudo-random number generator to simulate the variability inherent in biological systems.
