Groups with homologous characters share a common ancestor. These characters have the same embryological development, although their function might vary. Option D. share a common ancestor.
<h3>
What is a homologous character?</h3>
Homologous characters are structures with the same basic elements.
Their position in the body and the relations with adjacent structures are also the same in different organisms, and they even share the same embryological development.
These structures might show variations between the organisms exhibiting them. Variations might be related to their function and to the environment in which the organism lives. The function they accomplish is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
For example, whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development.
The correct option is then option D. Species with homologous structures most likely share a common ancestor.
