Question

Structures that have evolved separately but look very similar exhibit __________ evolution, in contrast, structures that evolved through modification from a common ancestral trait are ___ structures.

Answer 1

Answer:

Structures that have evolved separately but look very similar exhibit Convergent evolution, in contrast, structures that evolved through modification from a common ancestral trait are Divergent structures.

Answer 2

Answer: Convergent; Homologous

Explanation:

Convergent evolution is the process by which organisms of different species or distantly unrelated organisms evolve similar body structure or organs. It occurs when two species from unrelated lines develop the same traits or features.

Homologous is the evolution of structure in organisms, through common ancestral species or based upon their descent from a common evolutionary ancestor. Homology is contrasted with convergent, which is a functional similarity of structure based not upon common evolutionary origins but upon mere similarity of use.
