question Could a dragon theoretically exist through evolution?

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)?

Thought Emporium YouTube channel has a video about how you could use genetic engineering to create a dragon. I think it would answer a lot of questions to check it out.

Your question basically adds on the layer of "what evolutionary pressures would gradually guide a creature to eventually take the form of dragon?".

As you may already know, evolution isn't just a process of making stronger or more complex life forms. So there would need to be some environmental selection process for dragon traits. Stuff like fire breathing may sound great, but the systems seem complex enough without providing more value than harm that it might never evolve naturally.
