Question

homologous Arms and wings are homologous structures that reveal the ancient relationship between birds and four-legged animals. hɑˈmɑləgəs

Accepted Answer

Developing from the same or a similar part of a remote ancestor. In his famous discussion of the panda's thumb, Stephen Jay Gould carefully explains how this thumb is not homologous to the human thumb. Although the two digits are used in much the same way (the panda's thumb is essential for stripping bamboo of its tasty leaves, the staple of the panda's diet), the panda's thumb developed from a bone in its wrist and is an addition to the five “fingers” of its paw. The tiny stirrup and anvil bones of our inner ear, however, do seem to be homologous with the bones that allow a garter snake to swallow a frog whole
