I will say that this is a different and creative approach to the "human-looking" aliens trope in fiction. They were molded to look like us, that's all (and probably behave like us, since possession of a body type isn't very useful without the behavior patterns that go with it). Perhaps it was some junior Soia-Liron's science project.
Then, rather, this project was titled as "how these creatures will look after thousands of years, at the same time screwing telepathy to them and transferring them to the basis of our biochemistry."
Liron were clearly good at guessing.
The Wiki says fossil evidence for anatomically modern humans shows up around 300,000 years ago, tracking roughly with the end of the Soia. Assuming Loroi were modified from humans available at that time, modern Loroi should still look very similar to ancient Loroi, even considering the shorter generations. Even interbreeding between Homo Sapiens, Neanderthals and Denisovans has not significantly changed the human form in that time. It's not that the Soia-Liron were good at guessing, it's that Darwinian natural selection isn't as fast artificial selection or genetic engineering.

There are instances of morpohologically identical species on Earth having so little DNA in common that they are classified as completely different species (most are plants, however). It is not beyond reason that two species evolving on different worlds
might look the same (or similar) and still have different DNA.
There's way too much written about "template species" for that not to be what's going on. If humans and Loroi are not related in that way (either one based off the other or both based off a 3rd proto-human) then Chekhov will rise from his grave, grab his gun, and come knocking.
Besides, humans and Loroi aren't just similar, they are essentially identical. Blood and pigmentation being the notable difference. Add in that 300,000 years is not enough time for humans (and possibly Loroi as well) to have noticeably changed anatomically, and you should be able to rule out convergent evolution.

Loroi blood is not iron-based, and their normal body temp is about 15°C lower than that of Terrans. Some of their foods are antagonistic toward our physiology, as well. All of this implies different metabolic processes, which in turn implies different DNA, at least in the mitochondria.
The "Loroi Wiafus die due to uncontrollable necrosis" hypothesis isn't predicated being genetically or metabolically similar to humans. In fact, I suggested the metabolic difference would actually endanger the Loroi (body temperature too low to regulate human microbes, fever response inffective at stopping infection.) Bananas, horseshoe crabs, and humans all have very different genetics and metabolisms but
they all still rot. If Loroi bodies are made of different arrangements of mostly the same proteins and amino acids, then Loroi bodies will still look like food to fungi. Not that this is a story problem; space faring civilizations at this tech level will be well aware of the potential problem. And the Loroi are apparently confident in their antimicrobial therapeutics.

Is there Word of God on that somewhere? Not saying it isn't so, I just took the opposite implication.
To be clear, I meant Word of God on if the "template species" relationship means "created from scratch, but with careful attention paid to copy even the flaws and inefficiencies" or if that relationships means "modified from existing stock." I think it's the later. The first option means you have to justify the Soia deliberately creating sub-optimal designs while the second means you only have to justify the Soia being OK with designs that are "good enough."

Forum Digest: Loroi wrote:Despite their outward similarity, Loroi and humans are very different biochemically and genetically.
What does "very different genetically" means, exactly?... If the Loroi were derived from humans, they would not be described as being "very different genetically".
Yeah, phrases like "very different" are qualitative and depend on context so they're not that helpful. But the hypothesis doesn't depend on a degree of genetic similarity, but on a degree of biochemical similarity. And considering how similar the forms of the two species are, and what I think the "template species" relationship means, I would eat my hat and live stream it if humans and Loroi turn out to be made of mostly different stuff.

I mean, if you're going to engineer a new species
from scratch, why then would you also go through the effort of making it physically suspiciously similar to an existing species?
We do not know their motives. It's not just humans, we know they went and imitated other species, as we have the Barsam and the Nibiren. We can only extrapolate that the Neridi are also the imitation of another native species, one that might be extinct now, or that remains undiscovered. But for all we know, it could have been art... Ultimately, the motivation of the Soia-Liron doesn't matter...
Solid points. I'm reminded of a phrase that pops up sometimes when talking about alien or blue-orange morality: "We don't tame seals because we think balancing balls on noses is
useful." There really is a time for function to follow form.

Speculation: Terrans and the Soya-Loroi group may be able to trace their ancestry back to the same template, much like humans and apes have a common ancestor without having descended/evolved one from the other.
Never thought of that till I read your post, but I don't see why the true template species couldn't have been some proto-human. That would mean both the human and Loroi are unique among Soia-Liron species; Loroi are the sole known telepathic species and humans are the sole known telepathically inert species. The differences between the two would then be explained as being prerequisites for their respective telepathic abilities and the similarities explained as inherited from the template.
This bodes poorly for the infected waifu theory though, as it would imply a high degree of chemical similarities.

Loroi, in turn, live in the biosphere, in the overwhelming majority built on a different biochemistry. There are no terrestrial bacteria there. There are no earthly protozoa. There are no terrestrial plants and certainly no terrestrial animals...First of all, terrestrial viruses are absolutely safe for loroi. Because viruses can only interact with certain types of cell membranes and intracellular mechanisms ... which, for obvious reasons, you can hardly find in Loroi.
I agree 100% on viruses. But I was talking more about fungi/bacteria/protozoa. As you say, Loroi have had zero exposure to the terrestrial biosphere, so
if Loroi are vulnerable to terrestrial microorganisms, they certain to be immunologicaly naive. But we can safely expect off screen drugs to mean that a civilization ending human-Loroi pandemic will not be a plot point.

Secondly, since loroi and other types of Soya-Liron groups were created artificially, their creators probably knew about all the "pitfalls", some of which you raised in your thread. And it is likely that they have introduced mechanisms and algorithms into their creations that allow them to effectively deal with these problems.
Which?
We do not know. And if I were Jim, I wouldn't go into such questions. Trying to explain the structure of a hyperdrive in conventionally "hard" fiction has never been a good idea, even if you are fluent in the topic, which is unlikely.
There should be a hyperdrive, but let the reader figure out the subtleties of its device.
I actually expect some form of answer to the question of why the Loroi exist and look the way they do. Outsider has never been particularly
hard science fiction so I don't expect a deep dive into the genetic engineering weeds. But I do expect a light to be shone the relationship between the Soia, Loroi, and humans. Obviously not in chapter 3, but eventually.
