Homology structure definition
WebDarwin made sense of homologous structures by supplying an evolutionary explanation for them: A structure is similar among related organisms because those organisms have all descended from a common ancestor that had an equivalent trait. Ridley uses a specific definition of homology: "A similarity between species that is not functionally necessary." WebStructural traits are not commonly used to determine clades as such features may not necessarily indicate shared heritage. Traits that are similar because they are derived from common ancestry are termed homologous structures ; Traits that are superficially similar but were derived through separate evolutionary pathways are termed analogous structures
