TLDR
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.Abstract:
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. Here, we have examined 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. By sequencing regions both linked and unlinked to the red colour locus, we found a region that displays an almost perfect genotype by phenotype association across four species, H. melpomene, H. cydno, H. timareta, and H. heurippa. This particular segment is located 70 kb downstream of the red colour specification gene optix, and coalescent analysis indicates repeated introgression of adaptive alleles from H. melpomene into the H. cydno species clade. Our analytical methods complement recent genome scale data for the same region and suggest adaptive introgression has a crucial role in generating adaptive wing colour diversity in this group of butterflies.read more

Reanalysis suggests that genomic islands of speciation are due to reduced diversity, not reduced gene flow
Tami Cruickshank,Matthew W. Hahn +1 more
TL;DR: Testing the model of differential gene flow among loci by asking whether absolute divergence is also higher in the previously identified ‘islands’ finds that absolute measures of divergence are not higher in genomic islands, and simulations using the program IMa2 suggest that inferences of any gene flow may be incorrect in many comparisons.

TL;DR: Overall these results show that species divergence can occur in the face of persistent and genome-wide admixture over long periods of time.

Adaptive introgression in animals: examples and comparison to new mutation and standing variation as sources of adaptive variation.
TL;DR: The various attributes of these three potential sources of adaptive variation are compared, including balancing selection for multiple alleles for major histocompatibility complex (MHC), S and csd genes, pesticide resistance in mice, black colour in wolves and white colour in coyotes, Neanderthal or Denisovan ancestry in humans, and mimicry genes in Heliconius butterflies are examined.

Hybridization, Introgression, and the Nature of Species Boundaries
TL;DR: The nature of the species boundary is explored, defined as the phenotypes/genes/genome regions that remain differentiated in the face of potential hybridization and introgression, and it is emphasized that species boundaries are semipermeable, with permeability (gene exchange) being a function of genome region.

TL;DR: It is demonstrated that hybridization between two divergent lineages facilitated this process by providing genetic variation that subsequently became recombined and sorted into many new species, indicating rapid and extensive adaptive radiation.

TL;DR: Arlequin ver 3.0 as discussed by the authors is a software package integrating several basic and advanced methods for population genetics data analysis, like the computation of standard genetic diversity indices, the estimation of allele and haplotype frequencies, tests of departure from linkage equilibrium, departure from selective neutrality and demographic equilibrium, estimation or parameters from past population expansions, and thorough analyses of population subdivision under the AMOVA framework.
