homologous structures- same structure/different functions in common ancestors
analogous structures-same functions/differnt structures not in common ancestors
vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Homologous structures indicate that different species have a common evolutionary ancestor.
Correct.

It implies common ancestry.

Homologous structure
Homologous structures are those that have similar looks based upon a common ancestry. THE ANSWER IS HOMOLOGOUS STRUCTURES!!! On the other hand, analogous structures are structures that have the same function. Bats fly, but alligators walk.

Homologous structures are similar in structure but different in function, indicating shared ancestry (such as the bones in the limbs of humans and bats). Analogous structures have similar functions but different origins, suggesting convergent evolution (like the wings of birds and insects).
Homologous structures in different species are evidence of a common evolutionary ancestry. These structures have a similar origin, but may have different functions in different species. Studying homologous structures helps researchers understand how species have diverged and evolved over time.

homologous structures (correct answer, your response)
Though the forelimb of your cat or dog does not look much like your arms these are homologous structures that are almost identical bone for bone. This shows the common ancestry of all tetrapods and the closer common ancestry of you and your mammal pets.
