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.
We are usually not identical copies of each other. DNA is probably a far more complex chemical than we realize. There are probably super computers in there coded in a way we do not yet understand ~ and presumably they work in very small dimensions using quantum processes. What those processes might tap into is unknowable at present.
It is tempting to think DNA is linked to a great universal overmind ~ which enables it to not only be all things to all men, but also to be all men, all critters, all living things anywhere, under virtually all conditions.
Well, the thing is, people tend to treat DNA as if it were some sort of magic wand that answers all questions. It's not. DNA is merely a piece of evidence, just like fossilised bones are pieces of evidence.
The trick comes in how people choose to interpret the evidence. Evolutionists often choose to do so circularly.
