Palingenesis is a concept of rebirth or re-creation, used in various contexts in philosophy, theology, politics, and biology. Its meaning stems from Greek palin, meaning again, and genesis, meaning birth.
In biology, it is another word for recapitulation - the phase in the development of an organism in which its form and structure pass through the changes undergone in the evolution of the species. In theology, the word can be used to refer to reincarnation and Christian spiritual rebirth symbolized by baptism.
