Approximately 0.1% of humans who survive to birth carry a duplicon-related disability, meaning that several million people worldwide currently are afflicted by this particular subcategory of inborn metabolic errors. Many more afflicted individuals probably die in utero before their conditions are diagnosed. Clearly, humanity bears a substantial health burden from duplicon-mediated genomic malfunctions. This inescapable empirical truth is as understandable in the light of mechanistic genetic operations as it is unfathomable as the act of a loving higher intelligence. 
There you have it. Evil exists and a loving higher intelligence wouldn’t have done it that way. It is a powerful argument for evolution, but its power comes from religion, not science. And that is the story of evolution. From the pre Darwin Enlightenment years to today, these metaphysical arguments have mandated an evolutionary narrative. But the science reveals monumental problems. What Darwin and the evolutionists have done is to manipulate the science to fit our religious requirements. Theology is, and always has been, the queen of the sciences.
