I’m currently working through Robustness and Evolvability in Living Systems, and came across the following information which seems to be right in line with Denton’s evolution by natural law ideas:
A final, especially counterintuitive feature of RNA sequence space is that all frequent structures are near each other in sequence space. Consider a randomly chosen sequence that folds into a frequent structure and ask how far one has to step away from the original sequence to find a sequence that folds into this second structure…For instance, for RNAs of length n = 100 nucleotides, a sphere of r = 15 mutational steps contains with probability one a sequence for any common structure. This implies that one has to search a vanishingly small fraction of sequence space…to find all common structures.
