The chicken has recently joined the ever-growing list of fully sequenced animal genomes. Its unique features include expanded gene families involved in egg and feather production as well as more surprising large families, such as those for olfactory receptors. Comparisons with other vertebrate genomes move us closer to defining a set of essential vertebrate genes.
