Q. What is the relationship between the wing of a bird and the wing of a bat? (Solved)
1. They are homologous because they represent modified forms of a trait present in a common ancestor (forelimbs).
2. 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).
3. A and B.
4. They represent derived homologies.
- c. A and B.
