If two species have similar proteins and genes it means?
Correct answer: B. They have common ancestors
- A. They have the same organs
- B. They have common ancestors
- C. They have similar appearance
- D. All of the above
Explanation
The correct answer is that similar proteins and genes indicate a common ancestor. This is because genetic material is passed down through generations, and similarities can trace back to a shared lineage. The incorrect options suggest misleading connections; for example, having the same organs or similar appearance can be influenced by various factors and do not necessarily correlate with genetic similarity.

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.
