FISSION

n. splitting, cleaving; reproduction through division; splitting of an atom (Physics)

In general, fission is a splitting of something into its parts.Similar ways which this definition is used include:In physics, nuclear fission is a process where a large atomic nucleus (such as uranium) is split into two smaller nuclei.In biology, binary fission refers to the mitosis process whereby a prokaryote reproduces by cell division. It is similar to the mitosis and meiosis processes in eukaryotes.In anthropology, fission refers to the process whereby a nationstate divides and becomes multiple states (example: Yugoslavia).

n. fission

Reproduction In theosophical writing, usually confined to the various modes of physical procreation and excluding the production of offspring by kriyasakti. The essential principle in natural reproduction is that an individual separates a portion of itself, which then evolves independently into a similar individual. This may occur by fission, as in the amoeba and other unicellular forms, the mode of the first root-race of humanity. Or by budding, as in the sea anemone and many plants, and in the second root-race. By the throwing off of spores, as occurs in mosses and fungi. By the production of an egg, hatched within or without the body; the egg may contain the so-called positive and negative reproductive elements, and so be self-fertilizing; or it may contain only the negative element and so require fertilizing. The positive element may be contributed by the same individual as supplies the negative element; and then we have hermaphroditism. Or the positive and negative elements may be in different individuals, and we have the present usual mode of reproduction. The human body has at one time or another passed through all these states. Part of the second and the earlier third root-race were hermaphroditic, and the later third practiced ordinary sexual reproduction. Mankind is destined to transcend the present mode, which is but a passing phase in evolutionary history, and then pass to modes analogous to the modes which obtain on the descending arc.
