生物系统达到的组织复杂性远远超过任何已知的无生命物体的复杂性。生物实体无疑服从量子物理和统计力学的定律。然而,现代物理学是否足以充分描述、建模和解释生物复杂性的演化?统计热力学和生物进化的群体遗传学理论之间有详细的相似之处。基于这些相似性,我们概述了生物创新和进化中的主要转变的新观点,并引入了反映进化种群创新倾向的热力学势的生物当量。人们认为,生物实体和过程的性质与物理中的受挫状态(如玻璃)的性质之间也存在深刻的类比。我们通过考察挫折类型的现象,如生物进化中不同层次的选择之间的冲突,来扩展这种类比。我们进一步从渗流理论的角度讨论了多维适应度景观中的进化,并提出超过临界阈值的渗流决定了复杂生物的树状进化。总之,物理学和生物学基本过程之间的这些多重联系意味着,构建一个有意义的生物进化物理理论可能不会是徒劳的努力。

英文摘要:
  Biological systems reach organizational complexity that far exceeds the complexity of any known inanimate objects. Biological entities undoubtedly obey the laws of quantum physics and statistical mechanics. However, is modern physics sufficient to adequately describe, model and explain the evolution of biological complexity? Detailed parallels have been drawn between statistical thermodynamics and the population-genetic theory of biological evolution. Based on these parallels, we outline new perspectives on biological innovation and major transitions in evolution, and introduce a biological equivalent of thermodynamic potential that reflects the innovation propensity of an evolving population. Deep analogies have been suggested to also exist between the properties of biological entities and processes, and those of frustrated states in physics, such as glasses. We extend such analogies by examining frustration-type phenomena, such as conflicts between different levels of selection, in biological evolution. We further address evolution in multidimensional fitness landscapes from the point of view of percolation theory and suggest that percolation at level above the critical threshold dictates the tree-like evolution of complex organisms. Taken together, these multiple connections between fundamental processes in physics and biology imply that construction of a meaningful physical theory of biological evolution might not be a futile effort.
