When DNA is analyzed and plotted it doesn't support the diagrams that the evolutionists want us to take as truth.
I am not aware that there were huge discrepancies between DNA and other classifications. I am aware of small discrepancies; DNA is a better method of identifying descent than morphology, so that is not surprising.
Could you please supply a reference (and please don't bother with the creationist websites; they are doing apologetics, not science).
Oh, and evolutionists are not in the truth business. Try a church for that. Evolutionists and all other scientists deal with facts and theories, with theories being the best current explanations for facts.
Take a look at this chart, and read the caption. See anything about "truth" there?
