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

Hybridization among diverging lineages is common in nature. Genomic data provide a
special opportunity to characterize the history of hybridization and the genetic basis of …

The tree of life is highly reticulate, with the history of population divergence emerging from
populations of gene phylogenies that reflect histories of introgression, lineage sorting and …

The genus Quercus is among the most widespread and species‐rich tree genera in the
northern hemisphere. The extraordinary species diversity in America and Asia together with …

Summary Oaks (Quercus, Fagaceae) are the dominant tree genus of North America in
species number and biomass, and Mexico is a global center of oak diversity. Understanding …

Restriction-site associated DNA (RAD) sequencing and related methods rely on the
conservation of enzyme recognition sites to isolate homologous DNA fragments for …

The past decade has seen a major breakthrough in our ability to easily and inexpensively
sequence genome‐scale data from diverse lineages. The development of high‐throughput …

Resolving the genealogy of life—the phylogenetic relationships that describe the
evolutionary history of species—remains one of the great challenges of systematic biology …

As sequencing technologies become more affordable, it is now realistic to propose studying
the evolutionary history of virtually any organism on a genomic scale. However, when …
