"DNA could be proof for common design."
ERVs, which you know nothing about it and you never will know anything about it because you're too lazy to look things up, can't be explained by your magical designer.
Growing up, educating yourself, and facing facts is a wonderful thing, but god-soaked cowards don't want to do any of this.
"The Inquisition", this is not for you because you wouldn't understand it. This is for people who unlike you, are not afraid of science.
"We also harbor dead genes that came from other species, namely viruses. Some, called 'endogenous retroviruses' (ERVs), can make copies of their genome and insert them into the DNA of species they infect. (HIV is a retrovirus.) If the viruses infect the cells that make sperm and eggs, they can be passed on to future generations. The human genome contains thousands of such viruses, nearly all of them rendered harmless by mutations. They are the remnants of ancient infections. But some of these remnants sit in exactly the same location on the chromosomes of humans and chimpanzees. These were surely viruses that infected our common ancestor and were passed on to both descendants. Since there is almost no chance of viruses inserting themselves independently at exactly the same spot in two species, this points strongly to common ancestry."
-- Jerry Coyne, University of Chicago biologist and author of Why Evolution is True, an excellent book about the evidence for evolution which "The Inquisition" will never read because education makes "The Inquisition" cry.
