______structures are fully functional, show evidence of a common ancestor, and may or may not have
the same function in different species.

Homologous structures are similar organs or structures that are found in different animals that suggest they come from a common ancestor. This is evidence of evolution.

The structures might not necessarily look identical and might not perform the same function. For example, the flippers of a dolphin, the wings of a bird, the legs of a dog, and the arms of a human are considered homologous structures.

______structures are fully functional, show evidence of a common ancestor, and may or may not have the same function in different species.
