WebIn molecular evolution (including evolutionary genomics), the term “homology” means the sharing of evolutionary origin between two genomic elements (or among three or more elements). That is, two genomic elements are “homologous” to each other if they are descended from a common ancestral element (e.g., Fitch, 1970, 2000 ).
