Coo Coo Charles Darwin was fascinated by the domestic rock pigeon and used this dramatic example of diversity within a species to communicate his ideas about natural selection. Many derived traits in domestic pigeons converge on ecologically and evolutionarily relevant traits in wild species. Shapiro et al. (p. 1063, published online 31 January; see the cover) sequenced the genome of the domestic rock pigeon (Columba livia), along with those of 36 breeds and two feral accessions and its sister species, the hill pigeon (C. rupestris). The results reveal the underlying genetics of the head crest and suggest that all crested breeds may have originated from a single mutational event.
