About 98.8% of our DNA is non-coding DNA.  We don't know precisely what all of this is used for.  A large chunk of it is, as far as we know useless.  But, at any rate, in doesn't seem to have a direct impact on differentiating function or appearance in humans. It's not part of the human genome.

If we share all of that noncoding DNA with another animal, but not much of the coding DNA, the result would be a wildly different creature.  So, it's not surprising that a 1% change in DNA could lead to something entirely different.

You are a geneticist? ....or pub talk?

I'm a person who has an interest in science, and has studied up on certain topics.
