There is no theoretical reason to expect evolutionary lineages to increase in complexity with time, and no empirical evidence that they do so. Nevertheless, eukaryotic cells are more complex than prokaryotic ones, animals and plants are more complex than protists, and so on. This increase in complexity may have been achieved as a result of a series of major evolutionary transitions. These involved changes in the way information is stored and transmitted.
没有理论依据能预期进化谱系会随时间推移而增加复杂性，也没有实证证据表明它们确实如此。然而，真核细胞比原核细胞更复杂，动物和植物比原生生物更复杂，等等。这种复杂性的增加可能是一系列重大进化转变的结果。这些转变涉及信息存储和传递方式的变化。
