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.
- Adaptationism - Text by Anders Sandberg
The view that people should not adopt planets to suit themselves, but instead adapt to the planet. Adaptationists generally have a distaste for terraforming projects, or opt for only minimal terraforming, but instead prefer to use pantropy.

- 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.
- 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 matrix showing the various technological and biological characteristics which have been incorporated into the morphology and mindtype of a particular sophontological phyle or clade, tracing the connections of ancestry and descendants. The Genen are renowned for their elaborately decorated interactive cladograms.
