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 …
Homologies are everywhere - Understanding Evolution
WebOften, two species face a similar environmental condition or challenge. Evolution may then shape both of them in similar ways — resulting in convergent traits. For example, … Webhomology, in biology, similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor. Homology is contrasted with analogy, which is a functional similarity of structure based not upon common evolutionary origins but upon mere similarity of use.
