Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

The past fifty years have seen the development and application of numerous statistical
methods to identify genomic regions that appear to be shaped by natural selection. These …

The search for the alleles that matter, the quantitative trait nucleotides (QTNs) that underlie
heritable variation within populations and divergence among them, is a popular pursuit. But …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

There has long been interest in understanding the genetic basis of human adaptation. To
what extent are phenotypic differences among human populations driven by natural …

A major challenge in genetics is to identify genetic variants driving natural phenotypic
variation. However, current methods of genetic mapping have limited resolution. To address …

Enormous progress in mapping complex traits in humans has been made in the last 5 yr.
There has been early success for prevalent diseases with complex phenotypes. These …

The production of extreme or 'transgressive'phenotypes in segregating hybrid populations
has been speculated to contribute to niche divergence of hybrid lineages. Here, we assess …

Like the formation of animal species, plant speciation is characterized by the evolution of
barriers to genetic exchange between previously interbreeding populations. Prezygotic …

Efforts to identify the genetic basis of human adaptations from polymorphism data have
sought footprints of “classic selective sweeps”(in which a beneficial mutation arises and …
