How are homologies and analogies alike

WebThese are called analogous structures (Figure 2). Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. WebIn the illustration of forelimbs at left, homologous bones are colored alike. Biologists use a few criteria to help them decide whether a shared morphological character (such as the …
