Quotation from Darwin (Evolution)

George Jellis answered re' Haldane's Dilemma: "It seems to show that it is best to change one genetic trait at a time, which is what usually happens, rather than several at once." I agree with that conclusion, but it doesn't really answer Haldane's original mathematical conjecture: since mutations are at random, the chance is more than one trait can pop up at the same time, and bad and neutral mutations far outnumber beneficial mutations. It does seem that 'good' traits survive against all odds, or else evolution would not have created more and more complex organisms. Haldane was essentially asking, how can that happen? To my knowledge, that question has never been answered. My guess is that the current research into microRNA and interference RNA will eventually show that complex codes in RNA manage the problem.
