TL;DR: It is suggested that the advent of solid otoliths may have initially been a selectively neutral ‘by‐product’ of other key innovations during teleost evolution and the teleost‐specific genome duplication event may have paved the way for diversification in otolith shape.

TL;DR: In this article, the authors investigated the evolution of inner ears and accessory hearing structures (AHS) in fishes and how selective forces and/or constraints led to this inner ear diversity and how is the morphological variability linked to hearing abilities.

TL;DR: Both natural and sexual selection may contribute to isolation among parapatric populations, and selection against immigrants may be a powerful mechanism facilitating speciation among locally adapted populations even over very small spatial distances.

TL;DR: Comparison with common-garden reared fish detected a general decrease in brain size throughout populations in the lab, and little of the brain size divergence between lab-reared ecotypes that was seen in wild-caught fish.

TL;DR: morphometric and meristic characters of the fishes, as well as otolith morphology and morphometry, demonstrate that six phenotypic characters discriminate the A. dispar populations from the three studied basins, providing support for the assumption that the phenotypically different A.-disPar populations are a result of geographical isolation and not related to environmental differences.
