Homo sapphorians - TrinianGames/Sapphory GitHub Wiki
Homo sapphorians are an evolution of human beings. They are genetically distinct from Homo sapiens due to their complete lack of male hormones and the presence of an as-yet poorly understood androgen which appears to compensate. Homo sapphorians were created artificially by the process of Female Asexual Reprodution. All Sapphorian women are Homo sapphorians, and virtually every member of this species is a lesbian.
Genetics
Sapphorians are directly descended from H. sapiens and share the majority of their genetics with the rest of humanity. However, the lack of male hormones, normally present, and indeed required for good health in H. sapiens women sets them clearly taxonomically apart, as does the presence of the unknown and unnamed androgen in their blood which appears to compensate. It is likely that Founding Mother Kusankhana hacked this new hormone together in her lab to compensate for the variety of problems involved with creating an embryo without male material. It is also possible that she did not even completely understand it herself. As no notes or writings have survived from the period regarding this, if it ever was fully understood, that knowledge has now been lost and only the technique required to make Female Asexual Reprodution work remains.
It is unclear whether H. sapphorians could theoretically successfully interbreed with H. sapiens if such a thing were ever to become necessary. H. sapphorians do not menstruate and their ovaries function only in response to the injection of a serum which compels them to during breeding. As there are almost no Sapphorian women with heterosexual tendencies, experimentation in this regard is problematic and would be unethical. The Sapphorian Government has gamed out the scenario of Female Asexual Reprodution one day becoming ineffective but it is classified at the highest levels.
Sexuality
The main behavioural difference between H. sapphorians and other variants of the species is that homosexual tendencies among them are over 99.99% and heterosexual tendencies are so rare that they are a rounding error. This has yet to be explained by either scientists or psychologists, and study over the last few hundred years has been virtually non-existent as Sapphorians consider lesbianism to be completely normal and heterosexuality to be an aberration, though they are aware that their nation and species are a global outlier. Meanwhile, the outside world has little in the way of scientific methods and no Sapphorians upon which to experiment.
