As a dynamic process of genetic change, evolution manifests itself in two ways: It produces adaptive characters, and it produces species. To recognize that evolution has occurred by studying these products does not satisfy interested population geneticists. They see their science as providing an opportunity to contribute information that permits us to describe how the process of descent with genetic change occurs in populations of sexually reproducing, crossfertilizing organisms.

This volume reevaluates the position of population genetics in evolutionary biology by using population genetics as the tool to study the role of development and adaptation in evolution. The emphasis

Unintentional genetic processes in artificially maintained populations: Proving the leading role of selection in evolution

Evidence is presented indicating that selection is the leading evolutionary factor that regulates the operation of other factors, directly or through genetic systems.

The Measured Genotype Approach to Ecological Genetics

This chapter shows that recombinant DNA technology can also be applied to the area of ecological genetics; a subdiscipline of evolutionary biology that at first glance seems far removed from molecular genetics.

A Quantitative Genetic Perspective on Adaptive Evolution

The study of adaptive evolution is the concern of both ecology and genetics, and the intimate relationship between them is stressed.

Episodic Evolutionary Change in Local Populations

The incorporation of changes in the gene pool is viewed as a continuous process, with only small increments of change imposed by natural selection in each successive generation.

How large was the founding population of Darwin's finches?

The Mhc polymorphism is used to estimate the size of the founding population of Darwin's finches in the Galápagos Archipelago, and results indicate that the population could not have been smaller than 30 individuals.

Genetic Mapping as a Tool for Studying Speciation

The field of molecular systematics has developed rapidly in response to innovations in molecular biology such as recombinant DNA technology, the polymerase chain reaction (PCR), and efficient and cost-effective methods of DNA sequencing, but phylogenetic reconstruction represents only one of several contributions molecular biology has made to studies of systematics and evolution.

The role of molecular genetics in speciation studies.

This chapter illustrates how the bottom-up historical approaches used in population genetics can be extended upwards to this critical interface in order to separate the effects of population structure from population history, to rigorously test the species status of a group, and to test hypotheses about the process of speciation by using gene trees to define a nested, statistical analysis of biogeographic and other types of data.

Founder Effect Speciation: A Theoretical Reassessment

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.



Speciation and Sexual Selection in Hawaiian Drosophila

This simulation shows how the genes of an organism track the outer physical and organic properties of the ecosystem and shows how this affects the formation of species.

Genetic Variation and Phenotypic Evolution During Allopatric Speciation

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.

The theory of speciation via the founder principle.

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.

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).

Models of speciation by sexual selection on polygenic traits.

The models elucidate genetic mechanisms that can initiate or contribute to rapid speciation by sexual isolation and divergence of secondary sexual characters in polygamous species.

Isofemale Strains and Evolutionary Strategies in Natural Populations

Understanding of the nature and function of specific genes determining the genetic component of continuous variation is still poorly understood forms a major problem for the unravelling of underlying evolutionary strategies controlling such variation in natural populations.

Macroevolution: Pattern and Process

It is argued that only "quantum speciation" (rapid and radically divergent), can explain the story of life revealed in the fossil record; macroevolution, he contends, cannot be attributed to microevolutionary forces such as mutation, genetic drift and natural selection.

Evolutionary Genetics and the Genetic Control of Morphogenesis in Flowering Plants

The creative force in evolution undoubtedly is not mutation pressure, but selection, and it had to be shown that steady selection pressure could slowly and gradually alter characters by accumulating small additive effects of many genes.

A computer model of speciation by founder effects

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.

The response to selection on major and minor mutations affecting a metrical trait

Empirical data on natural and domesticated populations and analysis of the models suggests that strong selection sustained over several generations is usually required for adaptive evolution by a major mutation, in order to overcome deleterious pleiotropic effects generally associated with major mutations.
