recapitulation, theory, stated as the biogenetic law by E. H. Haeckel, that the embryological development of the individual repeats the stages in the evolutionary development of the species. For example, the beginnings of gill clefts appear in both humans and fish, but while they are elaborated and eventually function in the fish, in humans, except for the modified gill cleft that becomes the Eustachian tube, they disappear as the embryo develops. Though drastically modified and qualified since its proposal, the historical significance of this theory— "ontogenesis recapitulates phylogenesis" —is that with its appearance it lent support to the theory of evolution by seeming to corroborate it.

Recapitulation (Lat. recapitulatio; Gk., anakephalaiōsis, ‘summing up, summary’). In the writings of the Christian fathers, the restoration of fallen humanity to communion with God through the obedience of Christ. The concept derives from Ephesians 1. 10, where God is said to sum up all things in Christ, and was first elaborated by Irenaeus.
