DNA code is what we happen to be about as we are just beginning to learn. It is inescapably who we are. Contrasted by that was the meeting by humans of Neanderthal man. Which brought the end to Neanderthals. We know that everything is not created equal.
Humans are a very different lot.
Some of us are succeeding, thanks to a draw of good DNA, while many others will suffer from the lack of the same. Only proving our design has been a hap-hazard affair of trial and error. Something that has been going on in this biological theater for almost three billion years or more. As a species goes through their evolution anthropologists look for significant evidence that points to change. Searching for significant points of evolution.
