Q. In plants like $Acacia$, the leaves are compound but their seedlings possess simple leaves. This phenomenon can be explained by
A) Adaptive radiation concept by Darwin
B) Theory of inheritance of acquired characters by Lamarck
C) Recapitulation concept by von Baer

Explanation
Embryological Evidences in Plants Plants like Acacia, the leaves are compound but their seedling have simple leaves. This suggest their evolutionary relationship (biogenetic law), Haeckel’s biogenetic law states that ontogeny repeats phylogeny. Ontogeny is the life history of an organism, while phylogeny is the evolutionary history of the race of that organism. In other words an organism repeats its ancestral history during its development
