Beyond the obvious Not all homologies are obvious. If two homologous structures have been adapted for different roles, they may not look very much alike. For example, WebA modern concept of analogy is that of the agreement in use of characters (structures or functions), which have had a distinct evolutionary origin. There seems to be no special need for a return to a century-old concept of either analogy or homology. Both concepts-of homology and of analogy-should be recognized as involving grave complexities. 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. how do digital slot cars work
