These species hailed from three different evolutionary lineages.

这10种地衣来自三支不同的进化谱系。

Homo erectus was the first member of our evolutionary lineage.

直立人是我们进化谱系的第一个成员。

According to this idea, all organisms in the same evolutionary lineage are one species, going back to their most recent common ancestor.

根据这一观点，在同一进化谱系中的所有生物都是一个物种，可以追溯到它们最近的共同祖先。

Then they compared the code to that of a mammal whose evolutionary lineage split from ours about 80 million years ago: the mouse.

然后他们对比了老鼠的染色体序列。老鼠从8000晚年前开始分化出来。

The evolutionary lineage that led to our species, Homo sapiens, split from the one that led to our closest living relatives, chimpanzees, about 6-7 million years ago.

大约在600万到700万年前，这种进化使我们进化到我们这个物种——智人的谱系，与进化到我们现存的最近亲属——黑猩猩的谱系分离开来。

Turns out that regardless of evolutionary lineage, the animals react in a similar way to life among humans: they lose their antipredator traits.

事实证明， 无论进化谱系如何，这些动物对人类生活的反应方式相似：它们失去了反捕食者的特征。

With a technique called divergence-time analysis, scientists can use DNA to estimate when two evolutionary lineages split off from each other, based on the genetic differences they’ve built up.

通过一种称为发散时间分析的技术，科学家可以使用DNA根据它们建立的遗传差异来估计两个进化谱系何时彼此分离。

Turns out that regardless of evolutionary lineage, the animals react in a similar way to life among humans: they lose their antipredator traits. That pattern is especially pronounced for herbivores and for social species.

事实证明，不管进化谱系如何，这些动物对人类生活的反应是相似的: 它们失去了反捕食者的特征。 这种模式在食草动物和群居物种中尤为明显。
