According to the Biogenetic Law of Ernst Haeckel:
Correct answer: D. Ontogeny recapitulates phylogeny
- A. There is survival of the fittest
- B. There is use and disuse of organs
- C. Phylogeny recapitulates ontogeny
- D. Ontogeny recapitulates phylogeny
Explanation
This concept, proposed by Ernst Haeckel, suggests that the development of an individual organism (ontogeny) follows the same sequence of evolutionary changes seen in the evolutionary history of the species (phylogeny). According to this idea, an organism goes through stages during its development that resemble the adult forms of its evolutionary ancestors.

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.
