And conversely, that natural selection may perfectly well succeed in largely developing an organ without requiring as a necessary compensation the reduction of some adjoining part.

反过来说，自然选择完全可以成功地很大程度上发展出一个器官， 而无需作为必要的补偿来减少某些相邻部分。

Thus we can understand the greater size of rudimentary organs in the embryo relatively to the adjoining parts, and their lesser relative size in the adult.

因此，我们可以理解胚胎中的不完整器官相对于相邻部分的尺寸较大， 而在成体中它们的相对尺寸较小。

When one part is largely developed, perhaps it tends to draw nourishment from the adjoining parts; and every part of the structure which can be saved without detriment will be saved.

当一个部分得到很大发展时，它可能倾向于从相邻部分吸取营养；并且结构的每个可以保存而不会造成损害的部分都将被保存。
