Technology is a fickle thing. It is dependent upon the user's or users' input. No matter how great a study is, or how great the tools we employ are .... the person using it seems to be the most frequent point of failure.
Another way to say a similar idea is to say that guns don't kill people, people kill people. We do it every day in many different ways. We kill each other a little bit, over and over, and over again.

The most cherished goal in any of the fields of science (a new theory), as in bad romance novels, is unification.

The only sane response to a proposed unification is surprise .
Are we so surprised by Darwin's findings, that we are led astray regarding human evolution?
I leave it to you. Are you an expert ?
