“…out of such a potentially nondeterminist world, the organism has fashioned a very stable physiology and embryology. It is this robustness that suggested “vital forces”, and it is this robustness that we wish ultimately to understand in terms of chemistry. We will have such an opportunity in this new century.” Kirschner, Gerhart and Mitchison, 2000.
