flagellum

That vibration can then be coupled to another structure to turn a rotor, which in turn operates a flagellum-like tail..这个颤动能够随即作用到另一个装置以启动马达，后者接着操纵像鞭毛一样的尾巴。

Using special stains, one can see that some bacteria have attached to them wavy-looking “hairs” called flagella. Others have only one flagellum..用特殊的着色剂后，你会发现有的细菌上长着不少波状的"毛发"即鞭毛，而有的细菌只有一根鞭毛。

Thefinal evolution of the flagellum might then have involved only thenovel recombination of sophisticated parts that initially evolved forother purposes..鞭毛的最终出现，可能仅仅来自本来向其它方向进化的复杂器官的重新组合。
