Abstract
The expression patterns of developmental genes provide new markers that add ress the homology of body parts and provide clues as to how body plans have evolved. Such markers support the idea that insect wings evolved from limb s but refute the idea that insect and crustacean jaws are fundamentally dif ferent in structure. They also confirm that arthropod tagmosis reflects und erlying patterns of Hox gene regulation but they do not yet resolve to what extent Hox expression domains may serve to define segment homologies.
