Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

A long‐standing problem in evolutionary biology has been determining whether and how
gradual, incremental changes at the gene level can account for rapid speciation and bursts …

The study of speciation is concerned with understanding the connection between causes of
divergent evolution and the origin and maintenance of barriers to gene exchange between …

A major issue in evolutionary biology is explaining patterns of differentiation observed in
population genomic data, as divergence can be due to both direct selection on a locus and …

Phenotypic and genetic variation in one species can influence the composition of interacting
organisms within communities and across ecosystems. As a result, the divergence of one …

Our current understanding of speciation is often based on considering a relatively small
number of genes, sometimes in isolation of one another. Here, we describe a possible …

Many organisms enter a dormant state in their life cycle to deal with predictable changes in
environments over the course of a year. The timing of dormancy is therefore a key seasonal …

Ecological speciation with gene flow may be an important mode of diversification for
phytophagous insects. The recent shift of R hagoletis pomonella from its native host downy …

A major goal of evolutionary biology is to understand how variation within populations gets
partitioned into differences between reproductively isolated species. Here, we examine the …
