I tried to point out that they had human-shaped babies hatch out of eggs and he said that wasn't the point. The point is that unless I say it's all done by magic the "nerd" faction is going to get stuck on the point that the dragons knew about DNA and were able to somehow work it in an advanced chemistry setting hundreds of years ago.
Honestly there's no point here, at least as far as I'm concerned because I love the mental image of dragon chemists. But he said to let him know what you guys thought. So if you have a thought on this, and honestly I don't know that it could get much sillier, please post it so I can pass it along.
I think I may just put magic in to be on the safe side. Because I do know how much power the nerds have. Trust me on that one. *grin*
