Question

Theory of ontogeny recapitulates phylogeny was proposed by

• A. Mendel
• B. Haeckel
• C. Erasmus Darwin
• D. Weismann

Answer 1

The correct option is B Haeckel

Ernst Haeckel formulated his theory as "Ontogeny recapitulates phylogeny". “Ontogeny recapitulates phylogeny” was a commonly used phrase to explain the evidence supporting evolution. Ontogeny is “the complete developmental history of the individual organism,” and phylogeny is defined as “the complete evolutionary history of a group of organisms,”. Thus, this phrase means that the evolutionary history of a group of organisms is repeated during the developmental history of an individual organism of that group. This idea is also known as recapitulation.

Therefore, the correct answer is option B.
