Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Hybridization has played an important role in the evolution of many lineages. With the
growing availability of genomic tools and advancements in genomic analyses, it is becoming …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Because most plants rely on animals for pollination, insights from animal sensory ecology
and behavior are essential for understanding the evolution of flowers. In this review, we …

Reproductive isolation in plants occurs through multiple barriers that restrict gene flow
between populations, but their origins remain uncertain. Work in the past decade has shown …

Phylogenetic relationships among recently diverged species are often difficult to resolve due
to insufficient phylogenetic signal in available markers and/or conflict among gene trees …

Pollinator-driven diversification is thought to be a major source of floral variation in plants.
Our knowledge of this process is, however, limited to indirect assessments of evolutionary …

Background Flower coloration is a key enabler for pollinator attraction. Floral visual signals
comprise several components that are generated by specific anatomical structures and …
