Our rapidly increasing understanding of the human genome and those of other organisms means that we are becoming capable of genetically modifying ourselves by cutting out ,rearranging,and adding various snippes of our own DNA molecules and implanting DNA swquences form other organisms.This secondary evolution will allow us to change the course and speed of primary evolution (based mostly on the glacially slow process of natural selection) of our own species and other species by creating types of genes not currently found in the rest of nature.

我们很快地增加了对人类基因组以及那些其他生物的了解的方法，我们成为有能力从基因方面修改我们自己的基因，藉由删去关掉、重新排列、以及增加各种的片段在我们拥有的DNA分子以及注入一连串的DNA序列从其他生物，而这第二个发展出来的东西将是允许我们藉由创造的类型(创造的类型：不是属於现在处於自然界中的基因)改变初始发展的过程及速度(初始发展：主要是建立在兵期的缓慢的自然淘汰的过程)在於我们拥有的种类以及其他种类。
