Ciliate development requires assembly of functional genes from segments separated by intervening sequences now shown to have properties of transposons. This may be a relic of a time when transposition drove genome evolution, leading to the differentiation of the germline micronucleus and somatic macronucleus.
纤毛虫的发育需要从被间隔序列分隔的片段中组装功能基因，现在已表明这些间隔序列具有转座子的特性。这可能是转座驱动基因组进化时期的遗迹，导致了种系小核和体细胞大核的分化。
