Discerning Homologies: Gene Expression, Development, and Morphology.

Some of the most fundamental and interesting questions in evolutionary biology center on homology. Homology is our conceptual base for comparisons among organisms; it is the concept through which we explore plant diversity. This symposium will examine conceptual issues, methods, and data relevant to discerning morphological homologies. Speakers will explore morphological homology in light especially of gene expression and developmental data. Developmental genetics has provided vast new data that are being applied to hypothesize homologies and elucidate the evolutionary transformation of homologues. Those new data also raise important questions about conflicting hypotheses of homology based on gene expression and morphology. Developmental genetic data have also led to a resurgence of interest in concepts of partial homology that contrast greatly with some more traditional perspectives on homology.
