We regard the basic unit of the organism, the cell, as a complex dissipative natural process functioning under the second law of thermodynamics and the principle of least action. Organisms are conglomerates of information bearing cells that optimise the efficiency of energy (nutrient) extraction from its ecosystem. Dissipative processes, such as peptide folding and protein interaction, yield phenotypic information from which form and function emerge from cell to cell interactions within the organism. Organisms, in Darwin's 'proportional numbers', in turn interact to minimise the free energy of their ecosystems. Genetic variation plays no role in this holistic conceptualisation of the life process.
我们将生物体的基本单位——细胞，视为一个在热力学第二定律和最小作用量原理下运作的复杂耗散自然过程。生物体是承载信息的细胞的聚集体，这些细胞优化了从其生态系统中提取能量（营养物质）的效率。诸如肽折叠和蛋白质相互作用等耗散过程产生表型信息，生物体内部细胞间的相互作用从中产生形式和功能。按照达尔文所说的“比例数量”，生物体反过来相互作用，以使它们生态系统的自由能最小化。在生命过程的这种整体概念中，遗传变异不起作用。
