Verified by Experts

The correct Answer is:
A
The theory of recapitulation' or 'Biogenetic law', propounded by Haeckel states that an individual organism in its development (ontogeny) tends to repeat the stages passed through by its ancestors (phylogeny). During the life history of frog, tadpole larva resembles fishes, the ancestors of Amphibia. The presence of gill clefts in vertebrate embryo provides a strong evidence in support of organic evolution.
