In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

Epistasis occurs when the effect of a mutation depends on its carrier's genetic background.
Despite increasing evidence that epistasis for fitness is common, its role during evolution is …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

The genomic era has made clear that introgression, or the movement of genetic material
between species, is a common feature of evolution. Examples of both adaptive and …

Rates of hybridization are predicted to increase due to climate change and human activity
that cause redistribution of species and bring previously isolated populations into contact. At …

Interactions between alleles and across environments play an important role in the fitness of
hybrids and are at the heart of the speciation process. Fitness landscapes capture these …

Hybrid zones are important windows into the evolutionary dynamics of populations,
revealing how processes like introgression and adaptation structure population genomic …

Highlights•There is an increase in climate-induced hybridization among
insects.•Introgression seems to be the most common hybridization outcome in insects.•Long …

Human‐driven translocations of species have diverse evolutionary consequences such as
promoting hybridization between previously geographically isolated taxa. This is well …

Over most of the 20th century, evolutionary biologists predominantly subscribed to a strong
form of “micro-mutationism,” in which adaptive phenotypic divergence arises from allele …
