A common evolutionary branch of mindkind, defined by having a single common ancestor or common template (or both) which serves as the distinguishing characteristics for all members of that clade.
Although clades generally share a single origin or a small number of common ancestors (such as an original founding colony or community), it is also usually possible to join a clade by adopting the qualities of that clade in one's genome, physiology, ideology, and so on. Members of a clade generally differ markedly from other clades, in terms of morphogenic, cultural, religio-ideologico-memetic, and (if SI:1 or above) dendrotoposophic characteristics.
Quite often there are clades within clades. A biological/physiological clade may also be categorized according to the Linnean hierarchy of domain, kingdom, phylum, class, order, family genus, species and race, each one being a further monophyletic sub-division of the preceding. More usually, the Linnean system is too unwieldy to use in these contexts.
Cladism (adaptationist) - Text by Anders Sandberg The view that people should not adopt planets to suit themselves, but instead adapt to the planet. Cladists generally have a distaste for terraforming projects, or opt for only minimal terraforming.
Cladism (bias) - Text by Stephen Inniss An a priori bias for or against a particular clade of sophonts. As with bioism, mechanism, racism, and other such biases, this varies from a relatively benign admiration for or promotion of particular clades through to programs of enslavement or genocide.
Cladism (provolutionist) - Text by M. Alan Kazlev A preference for or tendency towards evolving into clades and sub-clades.
Cladistics - Text by M. Alan Kazlev The science of creating evolutionary trees of ancestry and descent; classifying organisms based on common ancestry and the branching of the evolutionary family tree. Organisms or entities that share common ancestors (and therefore have similar features) are grouped into taxonomic groups called clades. Cladistics can also be used to predict properties of yet-to-be discovered organisms. May refer to a biological phylogeny or a House or clan history.
Cladogram (evolution) - Text by M. Alan Kazlev Branching diagram that depicts divergence of the analysed taxa from their common ancestors. It shows the distribution and origins of unique shared characteristics (synapomorphies and autapomorphies), as well as their monophyly. A testable hypotheses of phylogenetic relationships.
Cladogram (sophontology) - Text by M. Alan Kazlev A precisely and scientifically organized family tree of a particular group or clade, tracing the connections of ancestry and descendants. The Genen are renowned for their elaborately decorated interactive cladograms.
Clan - Text by M. Alan Kazlev A clade or phyle, or more often, a sub-clade or sub-phyle. In some polities clan-links form the basis for much social interaction, political allegiance, government machinations, etc.
Dendrosequoia sapiens - Text by Steve Bowers 150 meter high sophont trees with biocomputronium cores; developed in the Biopolity and have spread to many worlds. Revered as spiritual leaders in some parts of the Sophic League.
Dorrahsa - Text by M. Alan Kazlev A race of small dinosaur provolves, the Dorrahsa spread widely during the early Empires period. Only one clade of Dorrahsa were settled on Owen, where they have reverted to a primitive culture. Those that are distributed through space are generally more intelligent, technologically savvy, and assimilate well into hu culture (mainly as companion sentients), although a few clades have a predilection for violent employment (mercenaries and piracy are common occupations, but only in conjunction with other races).
Gross Clade Product (GCP) - Text by John B A common numerical economic measure of the productivity of a specific clade. The acronym can also represent the Gross Civilization Product when referring to larger organizations of multiple clades.
Gynamorph - Text by M. Alan Kazlev Female-only erotorganic, usually a hu-animal splice (cat, bird, rabbit, etc) with heavily moldic genome and exaggerated primary and secondary sexual characteristics and exceptional sexual performance. Often used as a companion-sentient or in the sex-trade. In less civilized parts of the galaxy, may be referred to as a girldoll or toygirl (or worse). c.f. andromorph
Harrroh - Text by M. Alan Kazlev One of the most respected species of sufants, originally descended from Indian elephants. Most live on the terraformed planets of Yhrraini and Jhairrn in the (Utopia Sphere). They are widely admired as philosophers, playwrights, and artists.
Homo sapiens - Text by M. Alan Kazlev Large-brained hominid species that emerged perhaps 400,000 years ago (Heidelberg Man, etc.). Homo sapiens evolved from Homo erectus and eventually replaced Homo neanderthalensis to become the sole hominid species and subspecies. Includes thousands of subspecies, almost all of which date from post-Interplanetary period.
Homo sapiens species group - Text by M. Alan Kazlev A large and diverse group of hominid species that include Homo sapiens and many similar forms. See also Near-Baseline.
Hrruuaiih - Text by M. Alan Kazlev One of the most successful sufant clades, developed from African elephants, they have established a competitive sapient culture based on Hhrraiirah and a number of colony worlds. Bioborgization is common.
Lazarus Longidae - Text by Steve Bowers and Michael Capriola Tweak clade known to live for thousands of years. Named after a fictional character created by the Information Age novelist Robert A. Heinlein, who told Long's story as a series of memoirs. The Lazarus Longidae clade write all their long term memories down in very small thin leaved notebooks, use tiny shorthand ideogrammatic writing, and keep the notebooks in hundreds of small pockets in their overalls, moving all the notebooks around sequentially each time they fill one and throwing the oldest one away.
Space People - Text by M. Alan Kazlev  (archaic) A common early term for Space Adapted Humans, still used by some descendants of the original clade.  (Second Federation Era) A term for vacuum adapted tweaks, now rarely used.
Thym Olep - Text by Anders Sandberg Vec clade of the Metasoft Perseus border, who took Kja Observance ideas to an unusual extreme by adding genetic information transfer to their communications repertoire. They make bonobo chimpanzees look perfectly celibate, especially during the monthly accounting rushes.
