Analogous structures are similar structures in unrelated organisms. Analogous structures are structures which serve similar purposes yet are found in species that have come from different evolutionary lines. Considering the cited example analogous structures need not be of the same structure.
However even with having many of the dissimilarities these structures perform a similar type of functions. Analogous traits are adopted due to this type of evolution. Behavioral traits can also be analogous.
Both sets of arms have a similar structure and use and chimpanzees and humans share a common ancestor. How to use analogous in a sentence. Analogous definition is similar or comparable to something else either in general or in some specific detail.
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose. This process is known as convergent evolution. In general the wings of birds are modified forelimbs.
Showing an analogy or a likeness that permits one to draw an analogy. They may go through different developmental and functional stages before they are fully alike. One analogous structure might have come into existence long ago while the analogous match on another species may be relatively new.
