This sounds really weird. Supposedly, a taxonomic classification
represents (a hypothesis about) evolutionary descent.

We use morphology to deduce evolution.

We use "genetic differences" (whatever they may be?) to deduce evolution.

We use DNA-sequences (a selected number, not necessarily part of 
any gene) to deduce evolution.

Etc.

It all remains hypothetical, but genetic differences are not
necessarily very interesting.
