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).

- Dermal Coater / Dermal Coating - Text by John B
Biomeso neogen, that prefers open air and a warm substrate that exudes organics. Usually clear, occasionally tinted, rarely matte. Passed on through contact with contaminated surfaces (sponges, DNA scrapers, etc.)
- Designer Life - Text by Anders Sandberg
Designer life has existed since the Information Age, starting with glowing rabbits and bacteria with messages hidden in their genomes. Over time the design of new lifeforms as an artistic field has developed into a vast array of schools, approaches and applications. Some designer life correspond to individual artworks, others are intended to be integrated into ecological art, technical applications or even as citizen-artworks.
- Designer Phages - Text by Anders Sandberg
A major biotech field during the later information and early interplanetary periods. They are designer viruses that infect bacteria. The main use was to remove prokaryote biobots or infectious bacteria, but they could also be used for reprogramming biobots. Some biobots actually acted as factories for phages, and could be used to quickly produce large amounts of them.
- Dimimimon4ians - Text by M. Alan Kazlev
Generic term for biont clades created by Dimimimon4 in the mid 5th millennium a.t.. These included Clade Gikk, Clade Cromag, and Clad Fedhead.

Dragons of many different types have been created using lazurogenic and neogenic techniques, often from crocodile or avian genes.
- Erotogen - Text by M. Alan Kazlev with additions by Anders Sandberg and Tony Jones
A neogen or hu-animal splice with exaggerated primary and secondary sexual characteristics and exceptional sexual performance, generally used as a companion-sentient or in the sex-trade.

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.

- 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.
- 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.
