    Renowned Terragen scientist (early Interplanetary period) responsible for a major breakthrough in the field of gravitational theory. Along with predicting a number of effects which were later experimentally verified, Dr. Cheever's theory also led to the discovery of the 'Cheever Effect', a minuscule discrepancy in the relation between inertial and gravitational mass at the quantum level. At the time of its discovery, the Cheever Effect was thought to be of no practical importance, much like the 'ftl' effects seen in radio waveguides and other devices. It was not until centuries later, with the invention of the first reactionless drive, that an examination of Dr. Cheever's work was referenced as having provided the inspiration that led to the research that culminated in the invention of the drive.

    A phylogenetic group of organisms (whether biological, neumann-capable m-life, or alife) that shares a particular common ancestor, and therefore are related and share similar features.

The original term from studies of evolution has been adapted to other uses. For this see clade (sophontology).

    The property of an object or a system in which the elements or agents that compose it are diverse, connected, interdependent, and adapt to one another.

Complex systems produce novelty and may exhibit drastic phase changes at certain critical thresholds, yet at the same time they are often very robust. Organisms, ecosystems, societies and cultures, and economies all show high degrees of complexity. Many transapients and archailects are interested in complexity and hence encourage it.

  • Coral - Text by M. Alan Kazlev and Stephen Inniss
    Terragen marine metazoan animals, class Anthozoa, phylum Cnidaria. Though some are solitary, a typical coral is a colony of genetically identical polyps, each of which secretes calcium carbonate at its base to create a common skeleton with a characteristic structure. They are often brightly colored when alive, but after death of the polyp the color fades and becomes a bleached white. The best known and most numerous types of corals derive much of their sustenance from symbiotic photosynthetic algae. Because of this these are limited to regions of sunny shallow water and low nutrient flow, where bright light reaches the ocean floor. Such corals are an important element of many phototrophic tropical ocean biospheres.

Some coral reefs have been provolved to sapience.

  • Cyborn  - Text by Mike Parisi
    Cyborns in the general sense (as opposed to members of Clade Cyborn) have an organic component that is grown with the express purpose in mind beforehand of being "mated" with its cybernetic component. They are therefore unlike ordinary Cyborgs or Borgs, who typically began life as viable bionts or vecs but later added other components. They often refer to themselves as True Cyborgs. Typically the organic component is "grown into" its cybernetic component. The latter is laid out beforehand and serves as a scaffold for this growth.

    In a number of memeticities and religions, the idea that the universe undergoes periodic cycles of emergence and dissolution.
