Verginius Rufus: "If every species was created separately, why should there be any DNA in common at all between chimpanzees and human beings?"

Not sure what you mean by "created separately", but sure, it makes sense.

"If every species was created separately, why should there be any DNA in common at all between chimpanzees and human beings?"

Why would the DNA for certain cell configurations/types be 'different' in one creature vs. another ? Why 'reinvent the wheel' for every creature?

One might as well believe that the laws of physics are different on every planet.
