Extensive work in several model species has given us a detailed understanding of the mechanisms that guide the development of animals and plants. One remarkable outcome of these studies is the finding that the genes and pathways that underlie development are well conserved across large evolutionary distances, despite many of the obvious differences in the morphology of these organisms. Comparative approaches are now yielding insights into how conserved genetic pathways are altered by evolution to generate this diversity. Increasingly, the adoption of new species for detailed developmental studies plays a key role in uncovering these evolutionary changes, and these analyses are greatly facilitated by advances in many experimental and analytical techniques. I will discuss the insights obtained in understanding the evolution of body patterning and appendage diversification that have come from the study of arthropod evolution, highlighting our recent work on Homeotic (Hox) genes in the amphipod crustacean, Parhyale hawaiensis .
