  • Title: Arthropods: developmental diversity within a (super) phylum.
    Author: Akam M.
    Journal: Proc Natl Acad Sci U S A; 2000 Apr 25; 97(9):4438-41. PubMed ID: 10781039.
    Abstract:
    The expression patterns of developmental genes provide new markers that address 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 limbs but refute the idea that insect and crustacean jaws are fundamentally different in structure. They also confirm that arthropod tagmosis reflects underlying patterns of Hox gene regulation but they do not yet resolve to what extent Hox expression domains may serve to define segment homologies.
