Unfortunately, with DNA evidence on people long dead, you have much the same problem as the old bone-splicers of old - which is that modern investigators are piecing together disparate pieces of evidence to make them fit the picture that has already been pre-determined. In other words, the evidence tends to be made to fit the theory, instead of the other way around.
DNA is the new standard because the fossil ‘record’ didn’t work out. It will take a few years for ‘science’ to figure out that DNA doesn’t support evolution either, but never fear, there will be a new standard by then with lots of wiggle-room that just happens to support evolution.
The evidence fits the theory because the theory is just that good.
It also has great predictive power; without the theory of evolution to use as a guide, I'm not sure how we would use evidence collected about, e.g., a metabolic pathway in one species to make predictions about a similar metabolic pathway in a different species.
