That article is just the same old same old whirlwind in a junkyard argument.

He did not show that chiral molecules cannot emerge from series of series of chemical reactions over long time periods and under many changing environmental conditions. Once life was established, using molecules of particular chirality, then of course it continued to reproduce molecules of the same chirality. That is what reproduction means.

Your reasoning is based on a false assumption about my thoughts re' George. He is clearly using chemical evolution to get to one-handedness. I won't and can't do that. What you keep missing is that to have stable life that reproduces itself accurately, there are layers upon layers of control over DNA/RNA with microRNA, histones, etc. There are oodles of enormous molecules called enzymes that key-lock molecules to force extremely rapid reactions, that otherwise would take thousands or millions of years to potentiate. And then pile on the issue of chirality. Complex? Irreducibly complex. One part cannot work without the other. All have to be set up at the same time. Hoyle's 747 is an exact description of what is reqired, with all the jeering that George does. Don't denegrate Hoyle's intellect. He went to pan-spermia because he couldn't accept that the whirlwind did it here and here alone. Upset his atheism. All pan-spermia does is hide it elsewhere and not solve the problem of how it happened.
