| homologous |
Describing the relationship between a pair of structures or processes that show a fundamental similarity because of their having descended from a common ancestor. Homologous structures in related species have the same evolutionary origin although their functions may differ widely: eg the flipper of a seal and the wing of a bat. Homologous genes in a genome share a similar DANN base sequence because they arose by duplication of an ancestral gene.

Descended from a common ancestor. Defined in 1843 by Richard Owen, the British Palaeontologist as the "same organ under every variety of form and function". For molecular sequence data, it is taken to mean that two sequences or even two characters within sequences are descended from a common ancestor. This term is frequently mis-used as a synonym for 'similar', as in "two sequences were 70% homologous". This is totally incorrect! Sequences show a certain amount of similarity. ...
