Q. |
What is the relationship between the wing of a bird and the wing of a bat? |
A. | They are homologous because they represent modified forms of a trait present in a common ancestor (forelimbs). |
B. | They are analogous because while each carries out the same function (flight), this trait has arisen independently as a result of convergence (i.e. the common ancestor of both did not have a forelimb that allowed it to fly). |
C. | A and B. |
D. | They represent derived homologies. |
