Dietary adaptation is a major feature of phenotypic and ecological diversification, yet the genetic basis of dietary shifts is poorly understood. Among mammals, Neotropical leaf-nosed bats (family Phyllostomidae) show unmatched diversity in diet; …
Although cases of independent adaptation to the same dietary niche have been documented in mammalian ecology, the molecular correlates of such shifts are seldom known. Here, we used genomewide analyses of molecular evolution to examine two lineages …
Changes in behaviour may initiate shifts to new adaptive zones, with physical adap- tations for novel environments evolving later. While new mutations are commonly considered engines of adaptive change, sensory evolution enabling access to new …
