TL;DR: This article analyzed whole-genome divergence between replicate pairs of stick insect populations that are adapted to different host plants and undergoing parallel speciation, and found thousands of modest-sized genomic regions of accentuated divergence between populations, most of which are unique to individual population pairs.

TL;DR: Study of the evolution of cryptic body coloration and pattern in a stick insect using 25 years of field data, experiments, and genomics found that evolution is more difficult to predict when it involves a balance between multiple selective factors and uncertainty in environmental conditions than when it involved feedback loops that cause consistent back-and-forth fluctuations.

TL;DR: Intermediate phases of speciation are associated with genome-wide differentiation and mate choice, but not growth of a few genomic islands, and a gap in genomic differentiation between sympatric taxa that still exchange genes and those that do not is found.

TL;DR: It is documented that selection affected multiple genetic loci distributed across the genome, particularly in transplants to the novel host, and how genomic data can identify previously underappreciated ecological sources and phenotypic targets of selection is illustrated.
