One of the most common clades in the Terragen Sphere, Nearbaseline humans can be found in every major Sephirotic empire and most minor polities on the Periphery. Nearbaselines have been part of the Terragen Expansion from its earliest days, and in the millennia since then their vast numbers have given them enormous influence over modosophont societies. They slowly separated from Baseline humans over time, adopting the most popular genemods for themselves and their children, while not carefully controlling their development as Superiors do. The result has been an astonishingly diverse collection of human-derived cultures with many advantages over Baselines, though which ones they possess varies from one Nearbaseline clade to another.
Certain genemods have been adopted by almost all Nearbaselines, such as fertility control and life extension, while others are found only within specific local subcultures or ethnic groups. As a result, it is rare for Nearbaselines to be interfertile with one another, and interclade reproduction in the modern age is usually carried out by artificial methods for this reason. They can sometimes be difficult to distinguish from Tweaks, especially those with more extreme aesthetic modifications, but Nearbaselines still require earth-like conditions in which to live, while many tweak clades have adapted to very different conditions (such as a lack of gravity). Nearbaselines with minor adaptations for hostile environments, such as extra body fat for warmth or darkened skin for radiation tolerance, are usually not considered to be Tweaks.
Compared to their Baseline predecessors, Nearbaselines enjoy long natural lifespans of around four hundred years, robust health thanks to their enhanced immune systems, enhanced empathy, improved mental health, modular genetics for easy modding and greater compatibility with artificial implants such as Direct Neural Interfaces. They are usually not Superbrights, as although mental enhancements like innate calculating ability and inducible idea incubation are common among Nearbaselines, they are not integrated in such a manner as to produce truly superior intelligence. Nonetheless, even an average Nearbaseline would have been considered a genius by Old Earth standards, due to the endless opportunities for education and improvement that the Sephirotics provide.
The term 'Nearbaseline' dates back to First Federation census surveys, as a means of distinguishing Baseline humans with only one or two minor enhancements from Tweaks and Superiors, who tended to make more radical changes or even overhaul their entire genome. Since then, Baselines have declined almost to the point of extinction, and are so rare that the label 'Nearbaseline' has long since become redundant. The term persists to the present day due to cultural inertia if nothing else, though it is worth noting that many 'Nebs' are they are commonly known do not identify as such, regarding themselves first and foremost as members of their local subculture or polity. In addition to this, is is common for Nearbaselines to adopt Cyborg or Bioborg implants while still remaining mostly human. This has lead some commentators to regard the concept of 'Nearbaseline' as a spectrum of human-descended beings rather than a distinct category.
Despite the fact that divisions between different populations of Nearbaselines are far from clear, the Institute of Biological Taxonomy on Erasmus recognises some 36,000 modern subspecies of the clade. Some of the variants that developed early in the history of the Terragen expansion have become particularly widespread in the time since. These include H. s. lunensis, originally native to the domes and tunnels of Old Earth's moon and now found on low acceleration orbitals and moon-sized bodies across the Terragen Sphere; H. s. mediaphilus of the Nova orbitals and a number of other NoCoZo worlds; H. s. barnardensis and related subspecies; H. s. pacificus; and H. s. novaeterraensis, originally of New Earth, Terran Federation. Some argue that the more radically divergent Nearbaseline clades, such as the low-gravity adapted H. s. lunensis, would be better classified as Tweaks, and the preferred terminology is often more a matter of politics than of science.
One noteworthy trait of modern Nearbaseline cultures is that despite their willingness to modify themselves in line with the latest trends and fashions, relatively few of them ever permanently alter their form to a different clade of being. Many Nearbaselines will spend a century or two engenerated as a Provolve, Xenosophont or a Vec for the sake of variety, but most return to their original bodies, and the Nearbaseline population has held steady and even increased over time. This phenomenon has puzzled demographers and detractors alike for millennia, who often wonder how such conservative beings have persisted throughout the ages when they could become far more capable entities such as Superiors or Uploads.
Some have pointed out that enhanced abilities confer little advantage in a post-scarcity society where automated systems can meet all material needs. Others claim that their presence across Terragen civilisation from the very beginning has given them an advantage over clades that emerged later, as environmental and political systems have tended to be developed for human needs first and foremost. Whatever the reason may be, Nearbaselines continue to have a great deal of influence on modosophont society and culture by their sheer weight of numbers. Even now, they continue to settle new worlds, explore new ways of being and on rare occasions even ascend to the next toposophic level.
