The theory of speciation via the founder principle.
@article{Templeton1980TheTO, title={The theory of speciation via the founder principle.}, author={Alan R. Templeton}, journal={Genetics}, year={1980}, volume={94 4}, pages={ 1011-38 } }
The founder principle has been used to explain many instances of rapid speciation. Advances from theoretical population genetics are incorporated into MAYR's original founder-effect genetic-revolution model to yield a newer model called the genetic transilience. The basic theoretical edifice lies upon the fact that founder event can sometimes lead to an accumulation of inbreeding and an induction of gametic disequilibrium. This, in turn, causes alleles to be selected more for their homozygous…

Although rare, founder speciation can have a disproportionate importance in adaptive innovation and radiation, and examples are given to show that "rare" does not mean "unimportant" in evolution.
The role of founder effects on the evolution of reproductive isolation
- BiologyJournal of evolutionary biology
- 2013
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.
A computer model of speciation by founder effects
- Biology
- 1982
A computer model of a two-locus genetic system with epistatic selection was used to investigate factors influencing the probability of the origin of reproductive isolation, and it was concluded that it is unlikely to be a major cause of rapid speciation, although it could be a contributory factor.
Genetic Revolutions, Founder Effects, and Speciation
- Biology
- 1984
It is argued that, although founder effects may cause speciation under sufficiently stringent conditions, they are only one extreme of a continuous range of possibilities, and divergence may be driven in a variety of ways, without the need for drastic external changes.
In Defense of Founder-Flush Theories of Speciation
- BiologyThe American Naturalist
- 1996
There is no reason to dismiss founder-flush models of speciation because of their intrinsic implausibility or inconsistency with standard population genetics theory.
Genetic change after colonization

Consideration is given to the case of a daughter population of a sexual species that becomes successfully established in an area previously lacking that species, as has occurred recently in the…
Founder Effect Speciation: A Theoretical Reassessment
- BiologyThe American Naturalist
- 1996
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.
From nature to the laboratory: the impact of founder effects on adaptation
- BiologyJournal of evolutionary biology
- 2012
It is shown that evolution in a novel environment is strongly contingent not only on the initial composition of a newly founded population but also on the stochastic changes that occur during the first generations of colonization, which make laboratory populations poor guides to the evolutionary genetic properties of their ancestral wild populations.
Evolutionary Biology of Transient Unstable Populations
- BiologySpringer Berlin Heidelberg

An overview of speciation theory reveals an increasingly held view that many events leading to the origin of new species occur in transient, unstable populations. A transient, unstable population…
MODES OF SPECIATION AND INFERENCES BASED ON GENETIC DISTANCES
- BiologyEvolution; international journal of organic evolution
- 1980
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).

Stemming from Mayr's (1942; 1954) concept of the "founder principle", Carson (1968; 1971; 1973; 1975) hasdeveloped a somewhat unorthodox theory of speciation. Briefly, Carson views the steps in…

Speciation is ultimately an adaptive process that involves establishment of intrin sic barriers to gene flow between closely related populations by development of reproductive isolating mechanisms.

The utility of infinite population studies of linkage disequilibrium and its stable points is questioned, and considerable pessimism is expressed about the possibilities of distinguishing selection and sampling effects at linked loci.

The extra cilia of Drosophila silvestris is interpreted as a specific new embellishment of a secondary sexual character brought about by altered sexual selection occurring very recently in one part of the species range, suggesting incipient speciation.
