Vedclass · Answer

(D) The statement '$Ontogeny$ $recapitulates$ $phylogeny$' is known as the $Biogenetic$ $Law$ or $Haeckel's$ $Law$ of $Recapitulation$.It suggests that the developmental stages of an individual organism (ontogeny) reflect the evolutionary history of its species (phylogeny).Option $A$ is incorrect because stem cells are undifferentiated,not specialized.Option $B$ is incorrect because mammalian embryos do show vestigial gill slits during early development.Option $C$ is incorrect because only certain cells (like zygotes or meristematic cells) are totipotent,not all cells.
