Homology involves the theory that macroevolutionary relationships can be proven by the similarity in the anatomy and physiology of different animals. Since Darwin, homology has been cited in textbooks as a major proof for evolution. A review of the literature on homology indicates that the theory does not provide evidence for evolutionary naturalism, and that the common examples of homology can be better explained by Creation.
Homologous Structures. A homologous structure is an organ, system, or body part that shares a common ancestry in multiple organisms. This definition is found in evolutionary biology, and uses the meaning of having a similar structure or origin.he term homologous is used in several different modes in biology, all with meanings derived from the root phrase, having a similar relative position, structure, function or origin. In this lesson, we focused on homologous structures, homologous chromosomes and homologous organs in males and females.
