Botanists have long believed that hybrid speciation is important, especially after chromosomal doubling (allopolyploidy). Until recently, hybridization was not thought to play a very constructive part in animal evolution. Now, new genetic evidence suggests that hybrid speciation, even without polyploidy, is more common in plants and also animals than we thought.

Molecular evidence for asymmetric hybridization in three closely related sympatric species
TLDR
Although natural hybridization occurs in three Ligularia species, their hybrids seemed to be limited to the F1 generation and therefore species boundaries might be maintained. Expand
HYBRID SPECIATION AND INDEPENDENT EVOLUTION IN LINEAGES OF ALPINE BUTTERFLIES
TLDR
This work tested the hypothesis of hybrid speciation in butterflies occupying extreme, high‐altitude habitats in four mountain ranges in western North America with an explicit, probabilistic model, and genome‐wide DNA sequence data. Expand
Homoploid hybrid speciation in action
TLDR
It is concluded that homoploid hybrid speciation in action is likely to be a bottleneck in the development of new horticultural species and the number of hybrids needed to be bottlenecked is likely. Expand
Genome evolution and adaptation of a successful allopolyploid, Capsella bursa-pastoris
The term allopolyploid refers to an organism that originated through hybridization and increased its ploidy level by retaining the unreduced genomes of its parents. Both hybridization and polyploidExpand
Does hybridization between divergent progenitors drive whole‐genome duplication?
TLDR
The data simply demonstrate that hybridization between divergent parents has a higher probability of successfully producing a species if followed by polyploidization. Expand
Genetic admixture and lineage separation in a southern Andean plant
TLDR
It is found that diversity in two southern Andean Escallonia species is geographically structured and there is a deep divergence between infraspecific groups that could be associated with ancient evolutionary events like orogeny. Expand
A sexual hybrid and autopolyploids detected in seed from crosses between Neslia paniculata and Camelina sativa (Brassicaceae)
It is important to understand the probability of hybridization and potential for introgression of transgenic crop alleles into wild populations as part of pre-release risk assessment. Here we compl...
Homoploid hybrid speciation in animals
TLDR
It is argued that this evidence suggests that HHS is far more common than previously thought and this work uses it to provide insights into some of the genetic and ecological aspects associated with this type of speciation among animals. Expand
250 years of hybridization between two biennial herb species without speciation
TLDR
It is found that most of the London hybrids, between Tragopogon pratensis and T. porrifolius, exist naturally today in London, to all appearances the same. Expand
Hybridization can promote adaptive radiation by means of transgressive segregation.
TLDR
The model demonstrated that transgressive segregation through hybridization can facilitate adaptive radiation, most powerfully when novel vacant ecological niches are highly dissimilar, phenotypic effect size of mutations is small and there is moderate genetic differentiation between parental lineages.

Homoploid Hybrid Speciation in an Extreme Habitat
TLDR
It is found that the alpine-adapted butterflies in the genus Lycaeides are the product of hybrid speciation, and adaptive traits may allow for persistence in the environmentally extreme alpine habitat and reproductively isolate these populations from their parental species. Expand
Major Ecological Transitions in Wild Sunflowers Facilitated by Hybridization
TLDR
The same combinations of parental chromosomal segments required to generate extreme phenotypes in synthetic hybrids also occurred in ancient hybrids, and this possibility was tested through phenotypic and genomic comparisons of ancient and synthetic hybrids. Expand
Hybrid Origins of Plant Species
TLDR
Experimental, theoretical, and empirical studies of homoploid hybrid speciation suggest that it is feasible, although evolutionary conditions are stringent, and hybridization may be important as a stimulus for the genetic or chromosomal reorganization envisioned in founder effect and saltational models of speciation. Expand
Plant Speciation
TLDR
Polyploid speciation, in which the entire genome is duplicated, is particularly frequent in plants, perhaps because polyploid plants often exhibit ecological differentiation, local dispersal, high fecundity, perennial life history, and self-fertilization or asexual reproduction. Expand
The likelihood of homoploid hybrid speciation
TLDR
The model is of recombinational speciation, in which chromosomal rearrangements between parental species result in poor fertility of F1 hybrids, but through recombination, novel homozygous types are formed that have restored fertility. Expand
Host shift to an invasive plant triggers rapid animal hybrid speciation
TLDR
The first case in which hybridization between two host-specific animals (tephritid fruitflies) is clearly associated with the shift to a new resource is reported, suggesting the frequency of homoploid hybrid speciation in animals may be higher than previously assumed. Expand

A recent analysis has shown that divergence between human and chimpanzee varies greatly across the genome. Although this is consistent with "hybridisation" between the diverging human and chimpExpand
Speciation by hybridization in Heliconius butterflies
TLDR
It is shown that a hybrid trait in an animal species can directly cause reproductive isolation, and that the phenotype of H. heurippa reproductively isolates it from both parental species. Expand
The ecological genetics of homoploid hybrid speciation.
TLDR
Overall, theory and empirical evidence gathered to date suggest that ecological selection is a major factor promoting homoploid hybrid speciation, with the strongest evidence coming from genetic studies. Expand
Speciation by reinforcement.

TLDR
The formation of new species must involve the evolution of barriers to gene flow within existing species, but how these barriers arise remains a problem and recent studies suggest serious limitations on the efficacy of reinforcing selection and a lack of well-substantiated examples. Expand
