It is only in the past five years that studies of speciation have truly entered the molecular era. Recent molecular analyses of a handful of genes that are involved in maintaining reproductive isolation between species (speciation genes) have provided some striking insights.

AbstractSpeciation can be viewed as the evolution of restrictions on the freedom of genetic recombination: new combinations of alleles can be generated within species, but alleles from different species cannot be brought together. Recently, there has been increasing realization that the role of chromosomal rearrangements in speciation might be ...

Recent studies on diverse taxa suggest that natural selection caused by shifts in ecology or invasions of novel habitats plays an important role in adaptive divergence and speciation. Exciting new studies integrating approaches from both the field and the laboratory suggest that ecological shifts can result in extremely rapid rates of evolutionary ...

Called the "mystery of mysteries" by Darwin, speciation is still a little-understood area of evolution. Genetic analysis, however, has yielded new generalizations about speciation and suggests promising avenues of research.

The literature on speciation has expanded dramatically in recent years, catalyzed by the emergence of new conceptual frameworks, new theoretical approaches, and new methods for characterizing pattern and inferring process. As a consequence, the language used to describe the speciation process has become more complex.

Species-level phylogenies derived from molecular data provide an indirect record of the speciation events that have led to extant species. This offers enormous potential for investigating the general causes and rates of speciation within clades. To make the most of this potential, we should ideally sample all the species in a higher group, such as a ...

The interrelations of physics and biology are discussed. It is shown that Darwin can be considered as one of the founders of the important field of contemporary physics called physics of dissipative structures or synergetics. The theories of gradual and punctual evolution are presented.

Speciation has a central place in evolution, linking genetic processes within populations to the generation of biological diversity. The formation of new species must involve the evolution of barriers to gene flow within existing species, but how these barriers arise remains a problem.

Many outstanding questions about speciation are difficult to test empirically because of a lack of suitable study systems. Here, we highlight studies of evolutionary ecology in urban environments to argue that cities provide ideal conditions that can be leveraged to study the speciation process.

AbstractThe field of speciation has seen much renewed interest in the past few years, with theoretical and empirical advances that have moved it from a descriptive field to a predictive and testable one. The goal of this review is to provide a general background on research on speciation as it pertains to fishes.
