Final answer:
Homologous structures share a common evolutionary pathway and genetic origin. An example of molecular homology is DNA and the proteins they code for.
Explanation:
Homologous Structures are traits that share a common evolutionary pathway and the same genes that code for them.
In the context of molecular homology, an example would be DNA and the proteins they code for.
This is in contrast to analogies, which are traits that look the same but evolved separately, like the fins of dolphins and sharks.
