A combination of predators and competition 捕食者和竞争者的到来
...and the locals do not like to share. 当地居民不喜欢分享
And they still dominate our deserts today. 如今它们依然主宰着我们的沙漠
Yet on the margins of this barren and lifeless landscape, 然而在这片贫瘠而无生命的陆地边缘
gradually forming the largest and most hostile desert the planet has ever seen. 逐渐形成 地球史上最大、环境最恶劣的沙漠
and a single immense land mass on the other, 在另一边形成了一个巨大的陆地
Facing little competition and no large predators, 竞争很少 而且没有大型捕食者
