For a start, the emu is an endotherm- it's warm blooded. That means all of its cells have to gain many times more mitochondria than the dinosaur
​
So you are suggesting that dinosaurs were cold-blooded? Are you sure about this?
​
Oh, and if it wants feathers, it's going to have to grow hair first (hair and feathers both come from follicles). Tough to do when you're covered in scales.
​
So, you are suggesting that dinosaurs didn't have feathers? Are you sure about this?

That's all well and good, Slevesque, that you are unconvinced by the hypothetical inter-relatedness. But that does leave us with the question - just how many pairs of animals were on the Ark in your estimation?
