We are once more discussing abiogenesis ... the theory that life can arise spontaneously from non-living materials. My difficulty with this theory is the need to believe that sheer chance can create something as complex as replicating molecules. The degree of disbelief will be proportionate to the degree of complexity, and this is where George and I disagree. - I enter the fray once again to add another layer of complexity to DNA/RNA that science is turning up. This finding is a discovery of feedback loops, which are ever present in living biochemistry, but these are loops between and among genes and as ususal work in both directions to speed up or slow down expression of the genes targeted by the loops. This is now in addition to the epigenetic nucleotides recently discovered. All by chance? My foot. http://sciencenow.sciencemag.org/cgi/content/full/2009/421/3 I predicted in my book that finding increasing complexity was certainly ahead in discovery, and as knowledge of complexity increased, faith in chance had to decrease.
