That birds carry the genetic potential for teeth does not imply that they evolved from reptiles or any other creature except other birds that may or may not have had teeth.

Never implied this. The question dealt with the evolution of the gizzard, fairly unrelated to the article.

All this shows is that most creatures have more built in adaptability and variation in their genetic potential than we would normally assume.

Exactly. Homeotic genes and heterochrony give further credence to this idea.

"Never implied this. The question dealt with the evolution of the gizzard, fairly unrelated to the article."

I wasn't responding to the gizzard discussion, I was responding to the article itself your post #1. And the article implies evolution with references to reptiles, "80 million year old genetic pathway" and the assumption that development of a beak caused the lost of teeth.

My point, which I think you understood, was that creatures were created with a lot of genetic potential. Thus Adam may have carried the genetic potential for pygmies to Amazons, and all the colors of the rainbow without the need for mutations or evolution to account for diversity.
