Abstract Many animal species remain separate not because their individuals fail to produce viable hybrids but they “choose” mate. However, we still know very little of the genetic mechanisms underlying changes in these mate preference behaviours. Heliconius butterflies display bright warning patterns, which also use recognize conspecifics. Here, couple QTL for divergence visual behaviours with population genomic and gene expression analyses neural tissue (central brain, optic lobes ommatidia) across development two sympatric species. Within a region containing 200 genes, identify five genes that are strongly associated divergent preferences. Three have previously been implicated key components signalling (specifically an ionotropic glutamate receptor regucalcins ), overall our candidates suggest shifts behaviour involve integration or processing. This would allow evolution without altering perception wider environment.

Hybridisation and introgression can dramatically alter the relationships among groups of species, leading to phylogenetic discordance across genome between populations. Introgression also erode species differences over time, but selection against at certain loci acts maintain postmating barriers. Theory predicts that barriers made up many throughout should lead a broad correlation recombination rate, which determines extent on deleterious foreign alleles will affect neutral physically linked loci. Here, we describe variation in genealogical three Heliconius butterflies: H. melpomene (mel), cydno (cyd), timareta (tim), using whole genomes 92 individuals, ask whether this be explained by heterogeneous introgression. We find vary predictably chromosomal scale. By quantifying rate admixture proportions, then show rates are predicted rate. This implies highly polygenic, with acting introgressed most genome. In addition, long chromosomes, have lower rates, produce stronger average than short chromosomes. Finally, consistent difference two pairs either side Andes, suggests architecture Our findings illustrate how combined effects hybridisation, recombination, natural selection, multitudes periods, sculpt species.

Horizontal gene transfer (HGT) is an important evolutionary force shaping prokaryotic and eukaryotic genomes. HGT-acquired genes have been sporadically reported in insects, a lineage containing >50% of animals. We systematically examined HGT 218 high-quality genomes diverse insects found that they acquired 1,410 exhibiting functions, including many not previously reported, via 741 distinct transfers from non-metazoan donors. Lepidopterans had the highest average number genes. introns exhibited substantially higher expression levels than lacking introns, suggesting intron gains were likely involved adaptation. Lastly, we used CRISPR-Cas9 system to edit prevalent unreported LOC105383139, which was transferred into last common ancestor moths butterflies. In diamondback moths, males LOC105383139 courted females significantly less. conclude has major contributor insect

Color pattern mimicry in Heliconius butterflies is a classic case study of complex trait adaptation via selection on few large effect genes. Association studies have linked color variation to handful noncoding regions, yet the presumptive cis-regulatory elements (CREs) that control patterning remain unknown. Here we combine chromatin assays, DNA sequence associations, and genome editing functionally characterize 5 gene optix . We were surprised find architecture characterized by pleiotropy regulatory fragility, where deletion individual has broad effects both wing vein development. Remarkably, found orthologous associate with convergence distantly related comimics, suggesting parallel coevolution ancestral facilitated mimicry. Our results support model evolution changes ancient, multifunctional underlie adaptive radiation.

Speciation is the process by which barriers to gene flow evolve between populations. Although we now know that speciation largely driven natural selection, knowledge of agents selection and genetic genomic mechanisms facilitate divergence required for a satisfactory theory speciation. In this essay, highlight three advances/problems in our understanding have arisen from studies genes regions underlie evolution reproductive isolation. First, describe how identification “speciation” makes it possible identify causing isolation, while also noting link genetics phenotypic intrinsic postzygotic remains tenuous. Second, discuss important role recombination suppressors facilitating with flow, but point out means timing become associated cold spots uncertain. Third, establish importance ancient variation speciation, although argue focus on evolutionarily young groups may bias conclusions favor relative new mutations.

Identifying regions of the genome that act as barriers to gene flow between recently diverged taxa has remained challenging given many evolutionary forces generate variation in genetic diversity and divergence along genome, stochastic nature this variation. Progress been impeded by a conceptual methodological divide analyses infer demographic history speciation scans aimed at identifying locally maladaptive alleles i.e. genomic flow. Here we implement genomewide IM blockwise likelihood estimation (gIMble), composite approach for quantification barriers, bridges divide. This analytic framework captures background selection against model isolation with migration (IM) heterogeneity effective population size (Ne) rate (me), respectively. Variation both parameters is estimated sliding windows via pre-computed grids. gIMble includes modules pre-processing/filtering data performing parametric bootstraps using coalescent simulations. To demonstrate new approach, analyse from well-studied pair sister species tropical butterflies known post-divergence flow: Heliconius melpomene H. cydno. Our uncover large-effect barrier loci (including well-known wing-pattern genes) genome-wide signal polygenic architecture.

Visual preferences are important drivers of mate choice and sexual selection, but little is known how they evolve at the genetic level. In this study, we took advantage diversity bright warning patterns displayed by Heliconius butterflies, which also used during choice. Combining behavioral, population genomic, expression analyses, show that two species have evolved same for red exchanging material through hybridization. Neural regucalcin1 correlates with visual preference across populations, disruption CRISPR-Cas9 impairs courtship toward conspecific females, providing a direct link between gene behavior. Our results support role hybridization behavioral evolution visually guided behaviors contributing to adaptation speciation encoded within genome.
