Guess what? As far as the Zhodani are concerned, it's actually not a retcon!I am not trying to say you can't do it. I am just trying to say that would be a massive retcon to the setting.
As Mike Wightman's CT Alien Module 4 quotation (above) points out, modern Zhodani have the taxonomical name Homo zhdotlas, meaning that they are described as a separate species of Homo (human) in the text, rather than a subspecies (otherwise they would be Homo sapiens zhdotlas). The text further points out that they are the product of a hybridization between two earlier species of human on Zhdant (Homo zhdatl and Homo vlastebr), the implication being that these two species evolved independent from each other, due to geographical isolation, from the original humans dropped off by the Ancients around -302,000.
I admit this was probably not the intent of the writer, and it's more likely that the taxonomy is a result of a misunderstanding of how its done rather than prima facie evidence that they were intended to be a distinct species from the start, but that is what it says, so that is what I am sticking with.
Someone at GURPS noticed this too, and explained it in GT: Humaniti it by saying that the Zhodani regard themselves as a separate species of human (Homo zhdotlas), while Imperial scientists do not (Homo sapiens zhdotlas), which is pretty much on point for both of them, attitude wise.
Interestingly, GT: Humaniti also hints at strong political pressures behind the Imperial classification schemes for humaniti, pointing out that until recently the Luriani were commonly regarded as a separate species of human (Homo luriani), but ever since the 'fall' of the Solomani Movement at the Imperial Court, they are classified as Homo sapiens luriani in official Imperial circles -- but absolutely nowhere else.
And the Luriani have definite compatibility issues with both Vilani and Solomani humans. Luriani-Imperial hybrids are always messed up, absent high TL genetic interventions.
Mongoose, for its part, describes the Luriani as being hominids but not humans. If this is true, then we have to invent an entirely new genus/species combination for them (Luriani sapiens? Pontus sapiens?) under the Hominini taxonomical tribe (the next step up from our genus), where they would be grouped with us (Homo) and our nearest cousins, the chimps and bonobos (Pan).
