C)analogous.
D)convergent adaptations.

Quizplus · Accepted Answer

Homologous structures are structures that have the same evolutionary origin, meaning they evolved from a similar structure in a common ancestor. Heterologous structures are structures that evolved independently and have different origins. Analogous structures are structures that have a similar function but different origins. Convergent adaptations are adaptations that have evolved independently but have similar functions, which may result in analogous structures. Therefore, only homologous structures fit the description of structures that evolved from the same structure in a common ancestor.
