Adaptive introgression across species boundaries in Heliconius butterflies.

PLoS Genetics, 2012
It is widely documented that hybridisation occurs between many closely related species, but the importance of introgression in adaptive evolution remains unclear, especially in animals.

Introgressive Hybridization and Hypoxia Adaptation in High-Altitude Vertebrates [PDF]

Frontiers in Genetics, 2021
In natural populations of animals, a growing body of evidence suggests that introgressive hybridization may often serve as an important source of adaptive genetic variation.

Performance evaluation of adaptive introgression classification methods

Peer Community Journal
Introgression, the incorporation of foreign variants through hybridization and repeated backcross, is increasingly being studied for its potential evolutionary consequences, one of which is adaptive introgression (AI).

Inferring Adaptive Introgression Using Hidden Markov Models. [PDF]

Mol Biol Evol, 2021
Abstract Adaptive introgression—the flow of adaptive genetic variation between species or populations—has attracted significant interest in recent years and it has been implicated in a number of cases of adaptation, from pesticide resistance and immunity, to local adaptation.

Adaptive introgression: a plant perspective. [PDF]

Biol Lett, 2018
Introgression is emerging as an important source of novel genetic variation, alongside standing variation and mutation. It is adaptive when such introgressed alleles are maintained by natural selection. Recently, there has been an explosion in the number of studies on adaptive introgression.

Adaptive introgression of a visual preference gene. [PDF]

Science
Visual preferences are important drivers of mate choice and sexual selection, but little is known of how they evolve at the genetic level. In this study, we took advantage of the diversity of bright warning patterns displayed by Heliconius butterflies, which are also used during mate choice ...

Adaptive Introgression Facilitates Adaptation to High Latitudes in European Aspen (Populus tremula L.). [PDF]

Mol Biol Evol, 2021
Abstract Understanding local adaptation has become a key research area given the ongoing climate challenge and the concomitant requirement to conserve genetic resources. Perennial plants, such as forest trees, are good models to study local adaptation given their wide geographic distribution, largely outcrossing mating systems, and ...

Adaptation by introgression [PDF]

Journal of Biology, 2009
Both selective and random processes can affect the outcome of natural hybridization. A recent analysis in BMC Evolutionary Biology of natural hybridization between an introduced and a native salamander reveals the mosaic nature of introgression, which is probably caused by a combination of selection and demography.

Adaptive introgression: how polyploidy reshapes gene flow landscapes [PDF]

New Phytologist, 2021
SummaryRare yet accumulating evidence in both plants and animals shows that whole genome duplication (WGD, leading to polyploidy) can break down reproductive barriers, facilitating gene flow between otherwise isolated species. Recent population genomic studies in wild, outcrossing Arabidopsis arenosa and Arabidopsis lyrata indicate that this WGD ...

Prevalence and Adaptive Impact of Introgression

Annual Review of Genetics, 2021
Alleles that introgress between species can influence the evolutionary and ecological fate of species exposed to novel environments. Hybrid offspring of different species are often unfit, and yet it has long been argued that introgression can be a potent force in evolution, especially in plants. Over the last two decades, genomic data have increasingly
