Which of the following is evidence of a common ancestor?
Correct answer: D. All of the above
- A. Morphological similarities
- B. Fossil record
- C. Vestigial characteristics
- D. All of the above
Explanation
All the provided options are correct, as they each offer evidence of evolution from a common ancestor. Morphological similarities indicate shared physical traits due to common ancestry. The fossil record provides a timeline of evolutionary changes, showing how species have diverged from common ancestors. Vestigial characteristics are remnants of ancestral features, further supporting the idea of shared ancestry. Thus, choosing 'All of the above' is the most comprehensive answer.

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.
