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 …

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 …

Ecological processes are central to the formation of new species when barriers to gene flow
(reproductive isolation) evolve between populations as a result of ecologically‐based …

Incompatibilities in interspecific hybrids, such as sterility and lethality, are widely observed
causes of reproductive isolation and thus contribute to speciation. Because hybrid …

All plant and animal species arise by speciation—the evolutionary splitting of one species
into two reproductively incompatible species. But until recently our understanding of the …

The long-standing goal of finding genes causing reproductive isolation is being achieved.
To better link the genetics with the process of speciation, we propose that 'speciation …

Postzygotic reproductive barriers such as sterility and lethality of hybrids are important for
establishing and maintaining reproductive isolation between species. Identifying the causal …

With increasing force, genetic divergence of mitochondrial DNA (mtDNA) is being argued as
the primary tool for discovery of animal species. Two thresholds of single-gene divergence …

The Dobzhansky-Muller model proposes that hybrid incompatibilities are caused by the
interaction between genes that have functionally diverged in the respective hybridizing …

The establishment of reproductive barriers between populations can fuel the evolution of
new species. A genetic framework for this process posits that “incompatible” interactions …
