The longest archipelago in the Pacific, Hawaii consists of over 100 ancient volcanic islands, stretching for 2,000 miles. Yet it is so remote that less than 500 kinds of animal settled herein 30 million years. But for those who did make it to this lush and fertile land, the world was their oyster. Here, coconut palms have been replaced by giant tree ferns standing over seven metres tall. From the 13 kinds of spider that made it here, over 100 new species evolved - like the happy-face spider. From just one species of fruit fly came over 1,000 others. And here, caterpillars were free to become carnivores.赤道以北，在离北美洲最近的大陆块2500英里处座落着世上最偏远的一列岛屿——夏威夷。作为太平洋中最长的群岛，夏威夷由100多个古老的火山岛屿组成，连绵2000英里。然而由于它太偏僻，三千万年来也只有不到500多种动物得以在此定居。但对那些成功抵达这个茂盛和富饶之地的生物来说，它们要什么有什么。这里的椰子树被大树蕨取代了，这些树有七米高。从13种来到这里的蜘蛛种类里进化出了一百多种新种类，像开心脸蜘蛛。从单一种果蝇进化出了一千多种其他种类。这里的毛毛虫也能自由变成食虫性。
