Analogous structures look different but function the same. For example, the wings of a bird and butterfly have very different structures but have the same function. THIS DOES NOT INDICATE A COMMON ANCESTOR.
Homologous structures look the same but function differently. For example, the wings of a bat and the arms of a human. They have a similar internal bone structure but serve very different purposes. THIS DOES INDICATE A COMMON ANCESTOR.
What types of structures are shown below, analogous or homologous?
