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 …

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 …

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 …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

How common is speciation‐with‐gene‐flow? How much does gene flow impact on
speciation? To answer questions like these requires understanding of the common …

Phylogenetic niche conservatism (PNC) is the tendency of lineages to retain their niche‐
related traits through speciation events. A recent surge in the availability of well‐sampled …

Understanding how pollen moves between species is critical to understanding speciation,
diversification, and evolution of flowering plants. For co-flowering species that share …

Reinforcement is the process by which reduced hybrid fitness generates selection favoring
the evolution of stronger prezygotic reproductive barriers between emerging species. Using …

Polymorphic species, in which multiple variants coexist within a population, are often used
as model systems in evolutionary biology. Recent research has been dominated by the …
