Discerning homologies: Gene expression, development, and morphology

Geeta, R [1].

Structure Trees, Species Trees and Homology.

Developmental genetic pathways that generate morphological structures may be considered to evolve just as genes do. Being subject to evolutionary changes, such pathways are expected to be related to each other as a tree. Such "structure trees" may reveal evolutionary phenomena such as duplication (serial homology, equivalent to gene paralogy) and incongruence with species trees. Morphological homology concepts and shoot morphology, development and evolution are explored using this framework.
