Molecules, developmental modules, and phenotypes: a combinatorial approach to homology.
Molecular phylogenetics and evolution - 1 Jun 1998

Abstract excerpt
Most traditional views of homology rely on two unwarranted premises: the pervasively hierarchical nature of biology, inclusive of the levels of genes, development, and morphology and the linear mapping of genes onto developmental schedules and of developmental schedules onto phenotypes. These premises are only occasionally verified. Hierarchical behavior is negated by gene duplication and exon shuffling at the...
