In biology, homology means shared features as a result of descent from a common ancestor. Similarity may also mean the two proteins have similar function.
WebDec 14, 2024 · Abstract. Homology is the fundamental determinant of the sameness of biological characters or traits. When two characters stand in a relation of homology, they belong to the same character kind. For example, the eyes of humans and birds are homologous as vertebrate eyes – that is, they are the same kind of character: vertebrate … WebNov 23, 2006 · Homology Homology is a specific explanation of similarity of form seen in the biological world. Similarities can often be explained by common descent; features are considered homologous if they are shown to be inherited from a common ancestor.
WebHomologous structures develop from similar embryonic substances and thus have similar basic structural and developmental patterns, reflecting common genetic endowments and evolutionary relationships. In marked contrast, analogous structures are superficially similar and serve similar functions but have quite different structural and developmental …
