Parthenogenesis

Developmental biologyPhysiology

Reproduction from an unfertilized egg, with no genetic contribution from a male. In nature it occurs in many lizards, fish, and insects. In the lab, "artificial parthenogenesis" is triggered by mimicking the signal a sperm normally delivers — often a pulse of calcium ions that depolarizes the egg membrane and starts the cleavage cascade. It is this electrical–ionic activation that keeps a "born from the network" origin, like Kiri's, from being wholly outside science.
