Structural aspects of bodies that are similar in different lineages due to from a common ancestor.

Homologies can be seen in phenotype as well as genotype. In phenotype those homologies can be versus more strictly . Morphological homologies fall into the phenotypic and anatomical categories.

Though morphological homologies provide a more complicated perspective on than do especially genotypic, i.e., molecular homologies, usually it is only morphological homologies that are present in fossils. As a consequence, morphological homologies have been and also continue to be crucial towards developing as to the of life.

Historically, that is before especially , morphological homologies were the dominant type of homologies considered when determining similarities among organisms. See also morphology, morphogenesis, and morphological species concept.
