论文里提供了几乎所有数据和代码，要好好学习一下这篇论文
今天推文的主要内容是重复其中 Extended Data Fig. 1 ，不对绘图代码进行仔细研究了，知道python里有一个 toytree的模块可以展示进化树，看了代码，应该是不如ggtree好用 帮助文档链接 https://toytree.readthedocs.io/en/latest/3-installation.html
github主页链接https://github.com/eaton-lab/toytree
还有一个模块是ipyrad，用来做群体遗传分析，帮助文档链接 https://ipyrad.readthedocs.io/en/master/
完整的作图代码

toyplot.svg.render(canvas, "./RAxML_bipartitions.fulldataset_withAyava_10scaff_mcov025_rmcov01_mar2021.svg")
保存的是svg格式，试了下保存pdf,遇到了报错，暂时不知道什么原因
最终结果
输出结果太长，就不在这里截图展示了
示例数据和代码可以自己到论文中获取
