Spontaneous generation

“Know that the creatures are of many kinds . . . some are created in wombs others [are created] by spontaneous regeneration (khalq al-sa'a) and come into existence by themselves, such as the animals that are created in fruits, and a group are created in eggs. These are the types of creation of [living] things,”

(Abdul-Baha, Makatib, vol. 2, p. 24)
