And then if you run into another object, you can stay there and colonize the other object. So life will spread, then, from one object to another. So if it exists at all in the Kuiper Belt, it's likely to be very widespread. And you will have then a great competition amongst species -- Darwinian evolution -- so there'll be a huge advantage to the species which is able to jump from one place to another
假如你遇到别的障碍物 你就停在那里 作为你的殖民地 生命就这样繁衍开来 从这个物体到另一个物体不断的蔓延开去 所以假如柯伊伯带上确实有生物 它就很可能传播得很远 并且还将出现不同物种之间的争斗 也就是达尔文式的“物竞天择” 那些有幸到处漂的生物 就更有利于自身基因的传播
