Current Biology, 2022 Biologists have forever sought to understand how species arise and persist. Historically, species that rarely interbreed, or are reproductively isolated, were considered the norm, while those with incomplete reproductive isolation were considered less common.

Selective sorting of ancestral introgression in maize and teosinte along an elevational cline.
PLoS Genetics, 2021 While often deleterious, hybridization can also be a key source of genetic variation and pre-adapted haplotypes, enabling rapid evolution and niche expansion.

The recombination landscape of introgression in yeast.
PLoS GeneticsMeiotic recombination is an evolutionary force that acts by breaking up genomic linkage, increasing the efficacy of selection. Recombination is initiated with a double-strand break which is resolved via a crossover, which involves the reciprocal exchange

Introgression in interspecific hybrids of lily [PDF]
Acta Horticulturae, 2002 In order to introduce new desirable characters into the cultivar assortment of lily a range of interspecific crossing barriers has to be overcome. By using various pollination and embryo rescue techniques pre- and postfertilization barriers were overcome

Adaptive and maladaptive introgression in grapevine domestication
Proceedings of the National Academy of Sciences of the United States of America, 2023 Significance Our study focused on the history of introgression between domesticated grapes and their European wild relative. We find evidence for a single domestication of grapevine with introgression from the wild relative to wine, but not to table ...

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.

Nature Communications, 2022 Northern Hemisphere forests changed drastically in the early Eocene with the diversification of the oak family (Fagaceae). Cooling climates over the next 20 million years fostered the spread of temperate biomes that became increasingly dominated by oaks ...

Phylogenomic approaches to detecting and characterizing introgression
Genetics, 2021 Phylogenomics has revealed the remarkable frequency with which introgression occurs across the tree of life. These discoveries have been enabled by the rapid growth of methods designed to detect and characterize introgression from whole-genome sequencing

Recombination Variation Shapes Phylogeny and Introgression in Wild Diploid Strawberries
Molecular biology and evolution, 2023 Introgressive hybridization is widespread in wild plants and has important consequences. However, frequent hybridization between species makes the estimation of the species’ phylogeny challenging, and little is known about the genomic landscape of ...

The Contribution of Neanderthal Introgression to Modern Human Traits
Current Biology, 2022 DNA retrieved from ancient specimens revealed that Neanderthals, our closest extinct relatives, admixed (mated) with modern human contemporaries.
