Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Recombination, the exchange of DNA between maternal and paternal chromosomes during
meiosis, is an essential feature of sexual reproduction in nearly all multicellular organisms …

Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …

Parallel evolution across replicate populations has provided evolutionary biologists with
iconic examples of adaptation. When multiple populations colonize seemingly similar …

The fields of ecological and conservation genetics have developed greatly in recent
decades through the use of molecular markers to investigate organisms in their natural …

The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a
premier organism to study parallel evolution. These small fish have multiple distinct …

Recombination is a central biological process with implications for many areas in the life
sciences. Yet we are only beginning to appreciate variation in the recombination rate along …

The mode and extent of rapid evolution and genomic change in response to human
harvesting are key conservation issues. Although experiments and models have shown a …
