  • Here, the authors study adaptation to altitude in 518 whole genomes from two species of tropical butterflies. They find repeated genetic differentiation within species, little molecular parallelism between these species, and introgression from closely related species, concluding that standing genetic variation promotes parallel local adaptation.

  • The far-reaching effects of the relationship between an animal and its resident gut microorganisms are becoming ever clearer. New findings suggest it can even create barriers that keep species separate.

  • A phylogeny of Nymphalidae butterflies unveils the origin of the latitudinal diversity gradient. This study showed that the modern pattern of species richness emerged from dynamics of dispersal and diversification that varied through time and across regions, and that global climate change throughout the Cenozoic probably played a major role in generating the biodiversity pattern.

  • Two new studies show how highly divergent modes of male reproduction in a wading bird are controlled by alternate alleles at a single locus encompassing a 4.5-Mb inversion in the genome. The locus is an example of a 'supergene' controlling multiple complex phenotypes.

  • Genome sequences and gene-expression data from representatives of five distinct lineages of African cichlid fish reveal signatures of the genomic changes that underlie the astounding cichlid diversity seen today. See Article p.375

  • Breeding experiments re-created the intermediate wing coloration of Heliconius heurippa from H. cydno and H. melpomene, showing that its distinctive patterning reproductively isolates it from the parent species and that a hybrid trait directly causes reproductive isolation.

  • The diverse Heliconius butterflies have evolved key innovations, including pollen feeding, and are a quintessential example of adaptive radiation. Using comparative genomics, Cicconardi et al. identify targets of selection at coding and non-coding loci during major ecological transitions in Heliconius.

  • The genetic mechanisms underlying mate choice decisions can inform our understanding of speciation. A study on Heliconius butterflies identifies 5 candidate genes that would allow sympatric species to evolve distinct preferences without altering their visual perception of the wider environment.

  • Variation around colour pattern genes is highly modular in Heliconius butterflies. This modular architecture explains the diversity of colour patterns and provides a flexible mechanism for rapid morphological diversification.

  • Wing colour patterning of multiple species in the butterfly genus Heliconius is controlled by differential expression of the gene cortex, a member of a conserved family of cell cycle regulators.

  • Colour traits have been useful for studying the genetics underlying adaptive evolution. This Review discusses how genomic technologies are providing a deeper understanding of these traits, revealing fresh insights into their genetic architecture, evolvability and origins of adaptive variation.

  • In this Perspective, the authors discuss how regulated alternative splicing can generate phenotypic diversity and outline emerging evidence that alternative splicing contributes to adaptation and species divergence.

  • Genomic approaches are an increasingly important aspect of speciation research. The authors review recent insights from speciation genomics and propose a roadmap for this field, which is aimed at addressing both long-standing and emerging questions about speciation.
