there is no such thing as a hierarchy of evolutionary "advancement." The whole idea is just a biased claim that humans, particularly anglo-saxon males, are the best of all creatures on earth. Its a kind of ethnocentrism. Even when you get down to our human specialties that set us apart from other organisms, much of it is useless. Such as art, poetry, storytelling, and the rest enslaves us as much as it aids us. Every species has areas it is more "advanced in, but an entire species cannot take the spot of "most advanced" overall. That's all I'm saying. Sorry for being so picky, haha, I'm an anthropology major.
Anyway. I looked up the etymology of "stal" and think it best connects to "stale" which can be defined as "lacking freshness, palatability, or showing deterioration from age" by
http://www.tfode.com/Stale. Some words that came up on the list under the definition that stood out to me were 'rotten' and 'putrid.' So, assuming there is a connection here, I'd say all these skeletal enemies are just re-deads like someone suggested above, and not related after all.
And I don't think Stallord being locked away in a dungeon necessarily means he was human-like in terms of intelligence. Maybe no one could kill him, and the peoples' best bet was to imprison him and wait for him to die on his own. I mean, he IS a giant skeletal monster that spits some horrible . Is it also possible that people who lived in the desert worshiped him as a god? His head shows up as a symbol all throughout the temple. But then again, we really don't know much about the people who lived in the desert, or anything for sure about the origins of the temple/prison, and it is highly debated by people on here, so maybe its best to avoid the subject...
As for the fur, lets not forget that these are mythical monsters created for a video game. Let's not get into
another debate on the technical nomenclature of one of these imaginary things, anyone remember the Zora debate? Animals are clearly different in the Zeldaverse, and shouldn't always be held to our standards of classification. Stallord could still be some sort of dragon and still have fur in areas of his body. I think it makes him appear more horrifying to have hair hanging on to the bones...
In the end, I think we are ALL over-thinking it, but hey, what's wrong with that? As long as we don't get all angry and start attacking eachother, its all good!
