And for a while, they did, here on Wrangel Island off the coast of Siberia.

事实上的却如此，在西伯利亚海岸的弗兰格尔岛上，它们的确幸存了。

When people finally reached Wrangel Island 4,000 years ago, these last remaining mammoths also became extinct.

当4000年前，人类最终到达弗兰格尔岛后，这里的最后一支猛犸象族群也灭绝了。

There are no mammoths on Wrangel Island today, but it is home to another large animal, the polar bear.

如今，弗兰格尔岛上已经没有猛犸象了，但是这里又成为另一种大型动物的栖息地——北极熊。

But on Wrangel Island, these mammoths made their last stand.

And unfortunately, the Wrangel Island mammoths may have been doomed from the start.

不幸的是，弗兰格尔岛的猛犸象可能从一开始就注定失败。

The Wrangel mammoth's genome had about 20% less genetic variation, where different sequences of the same genes are inherited from each parent.

弗兰格尔猛犸象的基因组遗传变异减少了约 20%，相同基因的不同序列是从父母双方遗传而来的。

After extracting and sequencing the DNA from the Wrangel mammoth, researchers compared its genome to that of another, much older mammoth.

在对弗兰格尔猛犸象的 DNA 进行提取和测序后，研究人员将其基因组与另一只年长得多的猛犸象的基因组进行了比较。

This island -- now known as Wrangel Island -- was once connected to Siberia by land bridges and ice shelves.
