Homoploid hybrid speciation is the formation of a new hybrid species without change in chromosome number. So far, there has been a lack of direct molecular evidence for hybridization generating novel traits directly involved in animal speciation. Heliconius butterflies exhibit bright aposematic color patterns that also act as cues in assortative mating. Heliconius heurippa has been proposed as a hybrid species, and its color pattern can be recreated by introgression of the H. m. melpomene red…

Adaptive Introgression across Species Boundaries in Heliconius Butterflies
Analysis of the role of introgressive hybridisation in transferring adaptations between mimetic Heliconius butterflies, taking advantage of the recent identification of a gene regulating red wing patterns in this genus, finds an almost perfect genotype by phenotype association across four species.
Sex Chromosome Mosaicism and Hybrid Speciation among Tiger Swallowtail Butterflies
The results suggest that natural selection and sex-linked traits may have played an important role in the origin and maintenance of P. appalachiensis as a hybrid species despite contact and occasional hybridization with both parental species.
Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
It is inferred that closely related Heliconius species exchange protective colour-pattern genes promiscuously, implying that hybridization has an important role in adaptive radiation.

The theory and data supporting various aspects of the apparent paradox of ‘magic trait’ introgression are reviewed, with emphasis on population genomic comparisons of Heliconius melpomene and its close relatives.
An introgressed wing pattern acts as a mating cue
Results suggest that a color pattern trait gained by introgression is triggering RI between H. timareta subsp.
The signature of hybridization in the genome of a putative hybrid species, Xiphophorus clemenciae, is investigated through whole genome sequencing of this species and its hypothesized progenitors, and it is found that X. cle menciae is unlikely to have been derived from admixture between its proposed parental species.
Genome‐wide patterns of divergence and gene flow across a butterfly radiation
Phylogenetic analysis of 54 individuals robustly supported reciprocal monophyly of H. melpomene and Heliconius cydno and refuted previous phylogenetic hypotheses that H.Mel pomene may be paraphylectic with respect to H. Cydno.
Hybridization promotes speciation in Coenonympha butterflies
A series of approximate Bayesian computation procedures strongly suggest that the Darwin's Heath (Coenonympha darwiniana) originated through hybridization between the Pearly Heath and the Alpine Heath with different parental contributions, leading to the splitting of this taxon into two different species.
Evolution of novel mimicry rings facilitated by adaptive introgression in tropical butterflies
The findings support the role of regulatory modularity coupled with adaptive introgression as an elegant mechanism by which novel phenotypic combinations can evolve and fuel an adaptive radiation.
Homoploid hybrid origin of Yucca gloriosa: intersectional hybrid speciation in Yucca (Agavoideae, Asparagaceae)
It is shown that Yucca gloriosa (Asparagaceae: Agavoideae) is the product of intersectional hybridization between Y. aloifolia and Y. filamentosa, and multilocus analyses of the nuclear microsatellite markers provide strong support for the homoploid hybrid origin of Y. glorioa.


Hybrid trait speciation and Heliconius butterflies
It is argued that where hybridization leads to novel adaptive traits that also cause reproductive isolation, it is likely to trigger speciation, and proposed a novel term, ‘hybrid trait speciation’, which combines the idea that hybridization can generate adaptive novelty with the ‘magic trait’ model of ecological speciation.
Speciation by hybridization in Heliconius butterflies
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.
A Conserved Supergene Locus Controls Colour Pattern Diversity in Heliconius Butterflies
The results imply that a conserved yet relatively unconstrained mechanism underlying pattern switching can affect mimicry in radically different ways, and show that adaptive evolution, both convergent and diversifying, can occur by the repeated involvement of the same genomic regions.
Rapid hybrid speciation in wild sunflowers.
Estimating the sizes of parental species chromosomal blocks in Helianthus anomalus, a wild sunflower species derived via hybridization between H. annuus and H. petiolaris, provides a new and general method for estimating the tempo of hybrid speciation and dating the origin of hybrid zones.
Hybrid incompatibility is consistent with a hybrid origin of Heliconius heurippa Hewitson from its close relatives, Heliconius cydno Doubleday and Heliconius melpomene Linnaeus
Overall genomic compatibility is used as an alternative estimate of species relationships in a group where divergence is rapid and genetic exchange is common and backcrosses using F1 hybrid males provide evidence for a large Z(X)‐chromosome effect on sterility and for recessive autosomal sterility factors as predicted by Dominance Theory.
Assortative Mating Preferences Among Hybrids Offers a Route to Hybrid Speciation
Investigating the origin of this preference by studying first-generation backcross hybrids between H. melpomene and H. cydno implies that assortative mating preferences would facilitate the initial establishment of a homozygous hybrid color pattern by increasing the likelihood that early generation hybrids mate among themselves.
Gene flow and the genealogical history of Heliconius heurippa
It is suggested that ongoing introgression is frequent between all three species and variable in extent between loci, and seems to have also blurred the coalescent history of these species.
TEN Rapid speciation , hybridization and adaptive radiation in the Heliconius melpomene group james mallet
How recent genetic studies, together with ecological and behavioural observations, suggest that the shared colour patterns are indeed due to hybridization and transfer of mimicry adaptations between Heliconius species is detailed.
Genomic Hotspots for Adaptation: The Population Genetics of Müllerian Mimicry in the Heliconius melpomene Clade
Wing patterning loci in Heliconius melpomene show a haplotype structure maintained by selection, but no evidence for a recent selective sweep, but the complex genetic pattern contrasts with the simple genetic basis of many adaptive traits studied previously, but may provide a better model for most adaptation in natural populations that has arisen over millions rather than tens of years.
Polymorphic Butterfly Reveals the Missing Link in Ecological Speciation
Study of a butterfly population with a mimetic wing color polymorphism found that the butterflies exhibited partial, color-based, assortative mate preference, which represent the divergent, ecologically based signal and preference components of sexual isolation that usually distinguish incipient and sibling species.
