这里有一些代码在实现中可被重用；然而，在细化阶段的早期多数代码在服务于风险降低的目的之后就被抛弃了。

Some of this code survived in the implementation; however, early in the elaboration phase most of the code was thrown away after serving its risk-mitigation purpose.

由于现存的大多数物种生活在澳大利亚，早期的研究人员得出结论，巨蜥属起源于澳大利亚，随后沿着印澳群岛向西跳跃。

Because most existing species live in Australia, early researchers concluded that Varanus originated in Australia and subsequently island hopped westward along the Indo-Australian archipelago.

因此，你可能会想，现代陆龟可能从早期的陆栖时代就一直呆在陆地上，就像大多数哺乳动物，他们中的一些返回海洋之后所做的那样。
