Cichlid fishes are spectacularly species-rich and phenotypically diverse in morphology, behaviour and coloration, and therefore have become a 'non-model' model system for studying genomic diversification by natural and sexual selection [1-3].Many of the more than 2000 species have diversified based on ecological niche within lakes ...Summary: The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling ...Introduction. The fish-to-tetrapod transition during the Devonian is one of the prominent events in vertebrate evolution. The invasion of the land from the water necessitated the evolution of the novel structures in skeletons, musculatures, innervations, visceral organs, and respiratory systems in order to adapt to a terrestrial life (Romer, 1949; Clack, 2012; Dial et al., 2015).
