It's 1000 times older than Viking remains, and it even predates the existence of modern humans and Neanderthals.

它比維京人的遺蹟要古老1000倍，甚至比現代人類和尼安德特人的存在還要早。

Well, we have recovered DNA from mammoth teeth that have been buried in the Siberian permafrost for between 700,000 years and 1.2 million years.

我們從埋在西伯利亞永久凍土中70萬年到120萬年的猛獁象牙齒中找到了DNA。

This is the first time that anyone has recovered DNA from specimens that are more than a million years old.

這是第一次有人從超過100萬年的標本中恢復DNA。

This has been quite a challenge.

這是一個相當大的挑戰。

It has taken us several years to get the data out to analyze it.

我們花了幾年時間，才把數據拿出來分析。

What we have found is that one of the specimens, which we refer to as the crest of a mammoth, belonged thio previously unknown lineage or mammoth that we didn't know exist.

我們發現，其中一個標本，我們稱之為猛獁象的紋章，屬於以前未知的血統或我們不知道存在的猛獁象。

I think using ancient DNA like this is a bit like traveling back in time using a time machine so we can actually measure genetic changes.

我覺得用這樣的古代DNA有點像用時光機穿越回過去，這樣我們就可以真正測量基因的變化。
