In biological sciences, morphology is the branch that studies the form, external structure, and macroscopic organization of organisms and their parts, independent of function. It encompasses comparative morphology, which analyzes homologous structures across taxa; functional morphology, which relates structural features to mechanical or biomechanical constraints; and developmental morphology, which examines changes in form during ontogeny. Morphological data, including body plans, organ systems, and patterning of tissues, are central to systematics, phylogenetic inference, and taxonomy, and are integrated with molecular and genetic information to elucidate evolutionary relationships, phenotypic variation, and constraints on organismal design.
For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition—from a sprawled stance (like ...
