This family tree diagram is called a phylogenetic tree or cladogram.

该家谱图称为系统发育树或分支图。

And so the goal of a cladogram is to create what are called monophyletic groups.

因此，支序图的目标是创建所谓的单系群。

The one that we'll talk a lot about are called cladograms and they use what are called clades.

我们将论的是支序图，它们使用所谓的分支群。

The goal of a cladogram is to figure out all of life.

支序图的目标是弄清楚所有生命的形式。

And so cladograms are going to, it's the definitive answer of who's related to whom.

而且支序图会给出谁与谁相关的确定答案。

Last thing I said I would talk about are cladograms.

最后我要讲的是支序图。

And then at the end I am going to talk more about cladograms and how you create a cladogram.

然后在最后，我会更多地论支序图以及如何创建支序图。

When we are looking at a number of species and we want to place them in a cladogram, we assemble a dataset called a character matrix that contains lots of anatomical details of the species we are studying.

当我们查看多个种并希望将它们放在分支图中时，我们会组装一个称为字符矩阵的数据集，其中包含我们正在研究的种的解剖学细节。
