Final answer:
Structural similarity in correspondence theory refers to the similarity in physical features and genetic sequences between organisms, indicating common evolutionary paths. For example, the bones in the wings of bats and birds, arms of humans, and foreleg of a horse are homologous structures.
Step-by-step explanation:
In correspondence theory, structural similarity refers to the similarity in physical features and genetic sequences between organisms. Organisms that share similar physical features and genomes tend to be more closely related than those that do not. These similarities are called homologous structures and indicate common evolutionary paths. For example, the bones in the wings of bats and birds, arms of humans, and foreleg of a horse are homologous structures.
