9. The Darwinian, Lamarckian, and Wrightean modalities of evolution, robustness, evolvability, and the creative role of noise in evolution
The drama of Lamarckism
As the preface to this book pointed out, one of Darwin’s key achievements was demonstrating the essential interaction between chance and necessity in the evolution of life. According to Darwin, most of the heritable variation is random, and the directionality of evolution is brought about entirely by natural selection that governs the fixation or elimination of the random mutations (Darwin, 1859). As we have repeatedly discussed, randomness also substantially contributes to the fixation stage through the drift and draft routes, which are critically dependent on population dynamics (see ...
