Final answer:

Ontogeny recapitulates phylogeny is a historical hypothesis explaining the developmental similarities between embryos and their ancestors.


Explanation:

Ontogeny recapitulates phylogeny is a historical hypothesis from Ernst Haeckel that suggests the development of an animal's embryo reflects evolutionary stages of its ancestors. For example, vertebrate embryos demonstrating gill slits and tails showcase shared evolutionary history. This concept, though not universally applicable, highlights evolutionary connections between species through embryonic development.
