TL;DR: A high-quality reference genome assembly for threespine stickleback fish is developed and it is indicated that reuse of globally shared standing genetic variation has an important role in repeated evolution of distinct marine and freshwater sticklebacks, and in the maintenance of divergent ecotypes during early stages of reproductive isolation.

TL;DR: A quantitative trait loci study of a suite of 54 position traits describing body shapes of two threespine stickleback species suggested that sex differences may provide variation upon which selection can act, consistent with predictions of the geometric model of adaptation.

TL;DR: In this article, a large collection of quantitative trait loci (QTL) was used to address long-standing questions about the anatomical specificity, genetic dominance, and genomic clustering of loci controlling skeletal differences in evolving populations.

TL;DR: Parallel evolution of low-plated sticklebacks has occurred through a shared DNA regulatory change, which reduces the sensitivity of an EDA enhancer to Wnt signaling, and alters expression in developing armor plates while preserving expression in other tissues.
