Of similar function or appearance (compare: Homologous)
Greek ana = up, apart, towards, and logos = word. A part with similar function through different morphology e.g., fish gills and mammalian lungs (c.f. homologous).
In anatomy, similar in appearance or function but otherwise different. Two structures may be analogous if they serve the same purpose but differ evolutionary in origin as, for example, human and insect legs. As compared to homologous.
an organ or structure of one species is said to be analogous to an organ or structure of another organism when both structures have the same function; analogous structures do not necessarily indicate a close relationship between the organisms being compared but an adaptation to similar conditions... for example, the fins of a fish are analogous to the fins of a whale
Similar in structure, apperance or function but not in origin or development.
Alike in certain ways. Similar in function but not in origin or structure.
Two elements are analogous when they have the same operational functionality. Considering the function of flying, a bird and a plane may be considered analogous.
superficially similar characters with different underlying anatomies or embryonic development. e.g., wings of insects and bats (compare with homologous)
