उत्तर
Ontogeny repeats phylogeny is also known as theory of recapitulation.
Explanation:
This theory, also known as the biogenetic law, was postulated by Ernst Haeckel in 1866. It states that ontogeny (the embryonic development of an organism) recapitulates phylogeny (the evolutionary history of the organism's race). In other words, embryos during their development repeat the evolutionary history of their ancestors in abbreviated form. This theory is classically known as the theory of recapitulation.
