RECAPITULATION THEORY / BIOGENETIC LAW

It was proposed by Muller & Haeckel on the basis of Baer's law.

According to it, in the development of animal phylum characters are formed first & species characters are formed in the last.

Hackel proposed recapitulation theory & explained that 'ontogeny repeats phylogeny' i.e. ontogenic development of the animal repeats the evolutionary history of the animal.
