Gaussian distribution should get bell-shaped curves. New studies of randomness in DNA from many animals now sequenced does not find that result. IT appears evolution is not random: > > http://procrustes.blogtownhall.com/2010/03/17/gauss_ghost.thtml -But significant variations in individuals, with almost identical DNA, appear to be controlled by areas sulrrounding genes:- http://www.sciencedaily.com/releases/2010/03/100318141536.htm -And a review article, once again showing how complex the DNA mechanism is that controls gene edxpression and variability of the expression result. I've wondered all along and proposed that DNA actually drives evolution. This article suggests just that:-http://jbiol.com/content/8/11/95
