Genomics and the origin of species
Speciation is a fundamental evolutionary process, the knowledge of which is crucial for understanding the origins of biodiversity. Genomic approaches are an increasingly important aspect of thisExpand

Genetic and developmental basis of evolutionary pelvic reduction in threespine sticklebacks
Hindlimb loss has evolved repeatedly in many different animals by means of molecular mechanisms that are still unknown. To determine the number and type of genetic changes underlying pelvic reductionExpand

The probability of genetic parallelism and convergence in natural populations
Genomic and genetic methods allow investigation of how frequently the same genes are used by different populations during adaptive evolution, yielding insights into the predictability of evolution atExpand

The genetic architecture of divergence between threespine stickleback species
The genetic and molecular basis of morphological evolution is poorly understood, particularly in vertebrates. Genetic studies of the differences between naturally occurring vertebrate species haveExpand

Sex Determination: Why So Many Ways of Doing It?
Sex is universal amongst most eukaryotes, yet a remarkable diversity of sex determining mechanisms exists. We review our current understanding of how and why sex determination evolves in animals andExpand

The Genetic Architecture of Parallel Armor Plate Reduction in Threespine Sticklebacks
How many genetic changes control the evolution of new traits in natural populations? Are the same genetic changes seen in cases of parallel evolution? Despite long-standing interest in theseExpand

The Master Sex-Determination Locus in Threespine Sticklebacks Is on a Nascent Y Chromosome
BACKGROUND Many different environmental and genetic sex-determination mechanisms are found in nature. Closely related species can use different master sex-determination switches, suggesting thatExpand

Along the speciation continuum in sticklebacks.
Speciation can be viewed as a continuum, potentially divisible into several states: (1) continuous variation within panmictic populations, (2) partially discontinuous variation with minorExpand

PARALLEL AND NONPARALLEL ASPECTS OF ECOLOGICAL, PHENOTYPIC, AND GENETIC DIVERGENCE ACROSS REPLICATE POPULATION PAIRS OF LAKE AND STREAM STICKLEBACK
Parallel (or convergent) evolution provides strong evidence for a deterministic role of natural selection: similar phenotypes evolve when independent populations colonize similar environments. InExpand

Turnover of Sex Chromosomes in the Stickleback Fishes (Gasterosteidae)
Diverse sex-chromosome systems are found in vertebrates, particularly in teleost fishes, where different systems can be found in closely related species. Several mechanisms have been proposed for theExpand
