Stochastic processes at molecular, cellular and higher levels in organisms are not simply noise. Organisms also use stochasticity at all levels to generate new DNA sequences, as in the immune system, and new forms of behaviour, as in the nervous system. The harnessing of stochasticity therefore endows organisms with the means to actively influence the direction of their development and evolution.
生物体在分子、细胞和更高层次上的随机过程并不仅仅是噪声。生物体也在所有层次上利用随机性来产生新的 DNA 序列，如免疫系统，以及新的行为形式，如神经系统。因此，对随机性的利用使生物体具备了主动影响其发展和进化方向的手段。
