Artificial life forms are a characteristic part of habitats throughout the civilized galaxy. Even though natural Terragen and xenobiological species are popular as pets and companions, or as necessary members of any local biosphere or biohab ecology, often there is need for a completely artificial, custom-made life-form, a neogen. These are still fully organic, fully biological, and - unless specifically designed otherwise - are able to reproduce like any other organism. As with everything, boundaries are fuzzy: is a lazurogened Tyrannosaur made from respliced chicken DNA a neogen or not? For convenience, we can say that a neogen is a type that is totally new; it is not an attempt to enhance or to reconstruct a pre-existing species.
Although most neogens are subsapient organisms, there are still a large number of types that have either been designed as sapient from the start or provolved to sapience later. Such sapient neogens have played an important role in the history of Terragen civilization from the Interplanetary Age to the present day. Some, like the Goliaths, are specifically hominid, and can even be considered just one more form of nearbaseline or sub-superior clade, although they were custom gengineered. Others, like Synthetic Humans are essentially biological androids, although by phenotype they are indistinguishable from any human. Others again, like Erotogini, are specifically non-human, being essentially biological dildonics, even though many separate races and species of Moldie have been provolved to sapience, and today Moldies form an important element of galactic society, whether sub-sentient, subsapient, or fully sapient.
Inevitably, neogens have ended up in the sex trade, as companion sapients, bodyguards, soldiers, or fulfilling a particular role that may be unsuited to other sentients, or simply to add some local color.
Despite frequent rulings and local regulations to the contrary, and the best efforts of memegineers through the centuries, neogens frequently suffer from prejudice and even persecution at the hands of local nearbaselines and other subsingularity majority groups. For this reason, many neogens tend to be distrustful of mainstream galactic society, and tend to congregate in enclaves and free zones, or amongst other equally oppressed minority groups. In these polities they not infrequently become more prosperous than the surrounding nearbaseline communities (hence adding to the resentment among the ignorant, although intelligent neogens are able to play upon this for their own advantage).

Methane-respiring cold-adapted extremophile humanoids created by House Genen in the Zoeific Biopolity; very widespread and often actively involved in opposition to terraforming projects. Important faction in the Epp War.
- Neogen - Text by Todd Drashner
A biological being or species created entirely from scratch rather than by modification of naturally evolved stock. A product of neogenics, the technology of creating life from lifeless materials.
- Nu Joloth - Text by Morgan Heacock and Steve Bowers
Non-humanoid neogen clade.
- Octogen, Clade - Text by ThorbÃ¸rn Steen
A clade noted for its nano-dependent physiology and for its resulting skill in the nanotech design and construction.
- Praedatorius - Text by Michael Beck
A generic term, from the first creatures of this type, Homo praedatorius. Clades or individuals designed for military action, viewed with intense distrust by everyone else.
- Pteranodon People - Text by M. Alan Kazlev
Human-Pterosaur neogen-splice created by the Ptaphric Magic Potter.
- Rainbow Bubbles - Text by Liam Jones
Neogen species consisting of distinct spheres constituting a group mind.
- Shimmerers, The - Text by Liam Jones
Neogen/Neumann clade in the Serpens outer volumes.
- Soomia - Text by M. Alan Kazlev from original concept by Kevin Self
A clade of neogen-splice artist provolves, originally designed as companions to human artists. They long ago established an independent homeland in the Utopia Sphere and their own reputation for artistic talent. Soomia or gorups of Soomia tend to travel widely for extended and so are known throughout Terragen space.
- Tupilaks - Text by Anders Sandberg
Composite bioborgs or neogens, built from cultured organs or limbs. While not often seen much use outside specialised applications, building bioborgs from modular parts is sometimes more cost-effective than engineering entirely new species.
- Wup - Text by M. Alan Kazlev
Anti-culture secretionpunk movement. A Wuppista is a bioborg/neogen male with enhanced and enlarged genitals who would put on public performances, in which nearby property and bystanders would be sprayed with blood, urine, semen, saliva, feces, and, worst of all, wupple.
