So, this post has NOTHING to do with the events of Time Spiral or the rigamarole building up to that magnificent catastrophe.
Looking at Dominarian history, it seems that dragons have always had an especially prominent presence. Moreso than most of the other big, iconic creatures associated with the color wheel. The Numena played a big part in the upward mobility of humankind by taking down the Primevals; in this we see that dragons were once a major power upon Dominaria. Interestingly enough, looking back at the big inconics present in the early days of Dominaria's development: Angels, djinn, demons, dragons, elementals. Angels, Demons, and elementals are beings made purely of mana. Some of the djinn appear to be more constructs of the elements--wind, waves, water in its various states--and blue mana. Dragons are actual, organic beings. Given that dragons--and wurms--are some of Dominaria's oldest carbon-based life forms, I wonder why we don't see a greater distribution of reptilians upon Dominaria?
We have viashino in Shiv, these snake people from both Rath and whatever Dominarian continent was used for the Portal setting...and that's it for Dominaria's reptilian races. I'm not sure what logic there is in having the world overrun by various groups of elves, dwarves, goblins,minotaurs and merfolk instead of reptiles as the primary nonhuman races. It seems like there would be a more biologically sound argument for various species of viashino spread among the colors, various species of snakefolk among the colors, either throw backs from whatever gave rise to the dragons and wurms, or perhaps sharing some genetic inheritance with the dragons and wurms.
I was just curious as to why Dominaria was more or less a dumping ground for more traditional fantasy creatures instead of something that is both fairly unique (At the time of Dominaria's conception; I think Dragonlance was probably the only other WOTC property at the time that introduced my idea, in the form of their Draconians)and that makes a bit of sense when you consider how big a role dragons have played in the plane's history. That's a longwinded way of saying, sure I'm trying to do that on some level. The Phyrexians and Thran are already flirting with science fiction, so why stop there?
Because Dominaria was for a very long time the main setting of Magic as a whole. That is why they included as many fantasy tropes as possible in Dominaria. While other worlds were sometimes visited, the main focus was still Dominaria. This only changed with the first Mirrodin set and WotC's goal to visit a new plane every year. (The plan was later changed into "a new plane every year and sometimes a return to a beloved setting every once in a while")

But seriously though, what exactly is your point? Are you really trying to put "biological/ecological realism" into a fantasy setting?
