Note: Dragonborn in D&D are, despite the name, not directly related to dragons apart from "were created in the distant past" myths.
that depends who you ask... there are a few books that touch on dragons deliberately 'breading' humans in order to boost their numbers or act as an honor guard, then you have the Salvatore books that make it more of a spell gone wrong effect
Luke Skywalker: I don't, I don't believe it. Yoda: That is why you failed.
