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。
You might think, therefore, that modem land tortoises have probably stayed on land ever since those early terrestrial times, as most mammals did after a few of them went back to the sea.
可以肯定的是，这些水陆两栖物种的数据出现在接近三角坐标中间的位置，位于水栖海龟和陆栖乌龟的坐标点之间。
Sure enough, these amphibious species show up on the triangular graph approximately half way between the "wet cluster" of sea turtles and the "dry cluster" of land tortoises.
