This Hubble image shows NGC 1566, a spiral galaxy some 70 million light-years away in the constellation of Dorado. The color image was made from separate exposures taken in the visible, ultraviolet and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Understanding the genetic basis of convergence at broad phylogenetic scales remains a key challenge in biology. Kingfishers are a cosmopolitan bird radiation with diverse colors, diets, and feeding behaviors -- including the archetypal plunge-dive into water. Given the sensory and locomotor challenges associated with air-water transitions, kingfishers offer a powerful opportunity to explore the effects of convergent behaviors on the evolution of genomes and phenotypes, as well as direct comparisons between continental and island lineages. Eliason et al. use whole-genome sequencing of 30 diverse kingfisher species to identify the genomic signatures associated with convergent feeding behaviors. Image credit: Robert Balog.
