为了支持或反对生物进化中复杂性进化的趋势，复杂性需要既有严格的定义，又是可衡量的。最近一个信息论(但直观明显)的定义将基因组复杂性与一个序列存储的关于其环境的信息量联系在一起。我们调查了数字有机体种群中基因组复杂性的进化，并详细监测了增加复杂性的进化转变。我们证明，由于自然选择迫使基因组在固定的环境中表现为自然的“麦克斯韦恶魔”，基因组的复杂性被迫增加。
To make a case for or against a trend in the evolution of complexity in biological evolution, complexity needs to be both rigorously defined and measurable. A recent information-theoretic (but intuitively evident) definition identifies genomic complexity with the amount of information a sequence stores about its environment. We investigate the evolution of genomic complexity in populations of digital organisms and monitor in detail the evolutionary transitions that increase complexity. We show that, because natural selection forces genomes to behave as a natural "Maxwell Demon," within a fixed environment, genomic complexity is forced to increase.
