It provides a visual record in a complete series showing the evolution of an organism.
Correct answer: B. Fossil record
- A. Biogeography
- B. Fossil record
- C. Comparative anatomy
- D. Molecular biology
Explanation
The fossil record is a crucial piece of evidence for evolution, as it provides a chronological sequence of preserved remains or imprints found in sedimentary rocks, showcasing the gradual changes in organisms over time. It offers a visual and historical record of evolution, revealing transitions and ancestral forms. Other options, such as biogeography, comparative anatomy, and molecular biology, contribute to understanding evolution but do not provide a visual series of changes like the fossil record does.

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.
