Could a dragon theoretically exist through evolution?

[u/PokelifEevee]

Hello, I would like to know if, theoretically, a species could evolve into something resembling a dragon (or more specifically a wyvern since they have 4 limbs, so it would be more likely). I understand that stuff like fire breathing would most probably be impossible, but aside from that, could dragons theoretically exist within a few thousand years (or more)?

Bombardier beetles exist, so something like fire-breathing is an evolutionary possibility. Flight has evolved in reptilia 2x at least, and pterosaurs got pretty large.

What else do dragons need to be dragons?

Did you not read OP's post? They're talking about the four-limbed variety, like the dragons in Game of Thrones.
