Darwinian theory envisages 'selection pressure' as a stress imposed on the genotype by the environment. However, noise in the replicative and translational mechanisms in itself imposes a significant 'pressure' on the adaptive fitness of the organism. We propose that the biosphere has been shaped by both extrinsic (environmental) and intrinsic (noise-generated) factors. Because noise has been a remorseless and ever-present background to the evolutionary process, adaptations to this intrinsic pressure include not only a variety of familiar genetic mechanisms but also many anatomical and life-style characteristics that focus on the transmission of information between generations.
达尔文理论将“选择压力”设想为环境对基因型施加的一种压力。然而，复制和翻译机制中的噪声本身就对生物体的适应性健康施加了巨大的“压力”。我们认为，生物圈是由外在（环境）和内在（噪声产生）因素共同塑造的。由于噪声一直是进化过程中无情且始终存在的背景，对这种内在压力的适应不仅包括各种常见的遗传机制，还包括许多专注于代际间信息传递的解剖学和生活方式特征。
