Haeckel’s recapitulation theory/biogenetic law states
Open in App
Solution
The correct option is D Ontogeny repeats phylogeny
●According to the recapitulation theory, the embryo's developmental stage represents an adult form of an evolutionary ancestor.
●The term ontogeny relates with development of an organism from egg to adult and phylogeny deals with the study of evolutionary relationships among biological entities.
●Thus, according to Haeckel’s theory, ontogeny (development) repeats phylogeny.
Lamarck gave the theory of inheritance of acquired characters.
Darwin proposed that organisms have inherent power to increase their number,due to the high rate of reproduction.
Metagenesis is the alternation of generation exhibited by some organisms in which the asexual form alternates with the sexual forms.
