The "chimp DNA fallacy" is your own invention. The concept of common decent (which is by the way accepted by the more famous Intelligent Design advocates) is not simply based on two species sharing the same DNA.
If chimps and humans had a common ancestor, then we could make a workable logical formula from it - and we can't.
I believe in change over time, but new "kinds" have never evolved. All of the phyla appeared at one time as the Cambrian explosion clearly demonstrates. Evolutionists invent or interpret evidence in order to fit their preconceived presuppositions.
