In considering the mechanisms which could have led to the amazing variety of biological structures in the animal world, it has seemed reasonable to focus on the evolution of genomic regulatory pathways ((50), and Britten, this volume). Biological structure is the immediate result of developmental processes in which sets of diverse structural genes are expressed as ontogenically functional units. Such units must include genes that control the cell divisions in given tissue anlage or cell lineages, the nature of the products formed in the cells, their interactions with adjacent cells, and so forth. Relatives of most known structural genes seem to occur in a very wide phylogenetic range of creatures, while the specific patterns of development ...
