Are new species formed in rare catastrophes, distinct from the normal processes of phyletic evolution? Or does reproductive isolation evolve gradually, as a by-product of the divergence of gene pools? Mayr (120-124) has argued the former, holding that speciation usually results from genetic revolutions triggered by founder effects: An isolated population, small in numbers and in geographic extent, colonizes a new area. Both changes in selection pressures and genetic drift result in the rapid… 
Founder Effect Speciation: A Theoretical Reassessment
TLDR
The theoretical models demonstrated are closely related to the verbal schemes of Mayr's "genetic revolutions," Carson's founder-flush process, and Templeton's genetic transilience and demonstrate that founder effect speciation is plausible.
The role of founder effects on the evolution of reproductive isolation
TLDR
Experimental evolution is used to create one thousand replicates that underwent an extreme bottleneck and to study whether founder effects can lead to an increase in reproductive isolation in Drosophila yakuba, demonstrating that, similar to morphological and life‐history traits, behavioural traits can be affected by inbreeding and genetic drift.
Speciation and hybridization in island birds
The process of speciation in birds can be inferred from the pattern of diversification on islands, especially in archipelagos. The basic model is one of initial differentiation of allopatric
In Defense of Founder-Flush Theories of Speciation
TLDR
There is no reason to dismiss founder-flush models of speciation because of their intrinsic implausibility or inconsistency with standard population genetics theory.
The population genetics of speciation: the evolution of hybrid incompatibilities.
TLDR
The number of genic incompatibilities between taxa increases much faster than linearly with time, and it is "easier" to evolve complex hybrid incomp atibilities requiring the simultaneous action of three or more loci than to evolve simple incompatibles between pairs of genes.

GENETIC MODELS OF ADAPTATION AND GENE FLOW IN PERIPHERAL POPULATIONS
TLDR
A general conclusion is that disruption of gene flow can cause evolutionary divergence, perhaps leading to speciation, in the absence of contributions from random genetic drift.
Speciation in birds: Genes, geography, and sexual selection
TLDR
The challenge for ornithologists is to inform well studied examples of speciation in nature with increased molecular resolution—to clone speciation genes if they exist—and thereby evaluate the relative roles of extrinsic, intrinsic, deterministic, and stochastic causes for avian diversification.
Speciation and Macroevolution
TLDR
Dobzhansky reviewed the evidence from genetics, and argued that genetic variation between species was not different in kind from the genetic variation within species, and concluded that one may “reluctantly put an equal sign” between microand macroevolution.
Molecular Changes at Speciation
TLDR
This review examines the consequences of speciation for patterns of molecular genetic variation within and among populations and considers the following questions.

CATASTROPHIC SELECTION AS A FACTOR IN SPECIATION
TLDR
A study of species relationships in the genus Clarkia has led me to the conclusion that rapid speciation, involving an abrupt shift in adaptive mode and accompanied by barriers to gene exchange, represents the normal mode of speciation.
The theory of speciation via the founder principle.
TLDR
The genetic transilience model is used to explain several features of the evolution of the Hawaiian Drosophila, and experimental designs are outlined to test the major predictions of the theory.

TLDR
Investigating the validity of Mayr's founder effect-"genetic revolution" model from a population genetic perspective indicates that a founder effect can indeed induce rapid speciation, complete with preand/or post-mating isolating barriers, but the details and implications are far different from those portrayed by Mayr (1954).
Breeding Structure of Populations in Relation to Speciation
TLDR
There is no one rule either with respect to cross-sterility or to other characters in the process of speciation, and in some cases the most significant differences seem to be in chromosome number and organization.
Chromosome evolution and speciation in rodents
TLDR
Two alternative views look at the effects of different components of fitness in the role of chromosome change in speciation and adaptive evolution: fertility and/or fecundity in relation to the meiotic effects of rearranged chromosomes and phenotypic adaptation.
The Genetics of Speciation at the Diploid Level
TLDR
It is advanced that a diploid species has two differing systems of genetic variability, and speciation may occur as selection operates on the perturbed genetic system to organize new coadapted closed systems which come to characterize the new species.

TLDR
It is concluded that Mayr's theory of allopatric speciation overemphasized both the genetic cohesion of widespread species and the founder effect on heterozygosity and quantitative genetic variation, and data on the strength of natural selection and the spontaneous mutability of quantitative characters provide a feasible microevolutionary mechanism for substantial and geologically rapid phenotypic evolution in small isolated populations.
