Compare the following terms: homology and homoplasy. Provide two examples of each.
Homology
Homology refers to the similarity in structure, position, or evolutionary origin of traits among different species, indicating a common ancestral origin.
Homoplasy
The occurrence of similar traits in different species not due to common ancestry, often resulting from convergent evolution or evolutionary reversals.

Final Answer :
Homology is indicated when different features are derived from similar structures. A human arm and cat forelimb are identified as homologous structures because they have similar arrangements of bones, muscles, and nerves. Similar structures that have similar function but evolved independently are homoplastic structures. The wings of flying animals have the same function but evolved from different structures.
