Question

______structures are fully functional, show evidence of a common ancestor, and may or may not have

the same function in different species.

Answer 1

Homologous

Step-by-step explanation:

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.
