The Dragonians and their subspecies

[Chrono'99]

According to Korcha, a subspecies of the Dragonians exists or existed, apart from the main race:

This quote is from the "Unconfirmed dialogue" part of the script dump, which means that nobody has actually seen it while playing the game yet. We can read the text dump but not see the scene... so the question I have to ask is: is Korcha referring to the Hydras or the Dwarves when he mentions the Dragonian subspecies?

[ZeaLitY]

Are dwarves usually classified as mammals? If so, the Hydra (which seem to be Reptilian) would seem more like Dragonians. But a "subspecies" is weird. I guess part of them devolved into a swamp beast with no intelligence or communicative abilities.

[Legend of the Past]

I guess part of them devolved into a swamp beast with no intelligence or communicative abilities.

It seems more likely to me they came from the same roots but went a different evolutionary route. Saying they're a sub-species of Dragonians would therefore be like saying a chimp is a sub-species of humans-incorrect, but not without some essence of truth.
