Homology means
Correct answer: A. Similarity in characteristics resulting from common ancestors
- A. Similarity in characteristics resulting from common ancestors
- B. Similarity in function from acquired characteristics
- C. Study of different organs but with similar functions
- D. Study of similar organs but with different functions
Explanation
By definition, homology is similarity which results from shared ancestry: when similarity of a feature arises because organisms in two species or lineages share a recent common ancestor that possessed the feature then the features are said to be homologous. (It is important to include common ancestors in the definition)

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
