One of a number of invasive modosophont species-clades, humans (see above image) are aerobic, multicelluar, terrestrial bipedal endovertebrates with laevochiral biochemistry, bilateral symmetry, tripoblastic body plan, and a central nervous system.

Resourceful and fast-breeding (especially with exowombs)  they have become a ubiquitous species.  They include both plesiomorph (“primitive”), apomorph (“specialised”) and heteromorphic races and daughter clades, all descended from the original H. sapiens group of species, although there are also neogenic simulcra (replicants).


Humans first evolved on Sol-III and eventually achieved a reasonably high of civilisation.  Like many self-emergent technological species, humans almost destroyed themselves and their planetary biosphere before developing mature interplanetary travel, because of their political idiocracy which obstructed the establishment of a sustainable civilisation or even local space exploration.

They were rescued from certain extinction by the Ubbamuri (griftars), who were recruiting war-like species for a war against a rival civilisation, the Zheul.

Unfortunately  the Ubbamuri  and their allies were defeated, and the  Zheul occupied Sol Sys and began terraforming Earth before in turn being defeated by  the Somdosokon, at the time a powerful race of cybernetic organisms and invasive nanocyborg civilisation

Meanwhile, the descendants of the surviving humans flourished as an invasive and at times aggressive species and spread throughout the galaxy.

Current status

Like Lhouanthirshan  Rhursh, Tazori, and Vurruk, Humans are a common, adaptable,  but relatively low status species that have established a number of civilisations and empires, especially towards the low resource rim where trasingularitans are less common.  Over the million-odd years of their existence as a star-faring species, they have radiated out into a number of evolutionary forms, but the generic plesiomorphic  (or “nearbaseline”) type remains common on planetary habitats.  Human societies and psychology are little changed since pre Contact time, but those resourceful yet aggressive tendencies that were so destructive on their home planet have proved highly useful to society as an interstellar invasive.
