> DAVID: [i]Appearing in the last 3+ million years:[/i]-http://www.theatlantic.com/science/archive/2015/10/the-mystery-of-human-only-genes-and-...-QUOTE: "[i]One such unique human gene is HYDIN2. It first appeared around 3.1 million years ago, as a duplicate of an existing gene called HYDIN. During the duplication process, &#147;the head got chopped off and the tail got chopped off,&#148; explains Max Dougherty from the University of Washington. It was as if someone had transcribed a book but neglected the prologue and epilogue. That should have been a fatal mistake since the prologues of genes contain sequences called promoters, which switch them on or off. The new gene should have been dead on arrival&#151;a book that couldn&apos;t be opened.-"Instead, [b]as luck would have it,[/b] it fused with a copy of another gene, which gave it a new lease on life. The fusion, which Dougherty described at the American Society of Human Genetics 2015 conference, created an entirely original gene, which looks like HYDIN but with a new prologue and a new first chapter. And while HYDIN, like most of our genes, exists in many other animals, its wayward daughter&#151;HYDIN2&#151;is a human-only innovation.[/i] (David&apos;s bold)-David&apos;s comment: [i]Lucky or designed?[/i]-Weird! It certainly seems like a random mutation if the head and tail were chopped off during duplication, but the constructive fusion and the new human-specific genes described in the rest of the article suggest that intelligence is at work. More evidence of the autonomous ability of cells to work out ways of improving - or are you suggesting that God dabbled, or preprogrammed the chopping off process and fusion 3.8 billion years ago?
