PLoS Biology发表了一篇关于生命之树与生物多样性的观点论文。题目是：Walking and talking the tree of life: Why and how to teach about biodiversity。想想就很浪漫的一件事，生命之树重构的是生命从发源到现在的历史长河。作为有幸从事分类学、系统发育研究的科研工作者，可以在这棵树的一个分支上做一点点工作。闲来无事，在咖啡时间还可以到其它分支上去漫步，和其他同行讨论、讨论。
Taxonomic details of diversity are an essential scaffolding for biology education, yet outdated methods for teaching the tree of life (TOL), as implied by textbook content and usage, are still commonly employed. Here, we show that the traditional approach only vaguely represents evolutionary relationships, fails to denote major events in the history of life, and relies heavily on memorizing near-meaningless taxonomic ranks. Conversely, a clade-based strategy—focused on common ancestry, monophyletic groups, and derived functional traits—is explicitly based on Darwin’s “descent with modification,” provides students with a rational system for organizing the details of biodiversity, and readily lends itself to active learning techniques. We advocate for a phylogenetic classification that mirrors the TOL, a pedagogical format of increasingly complex but always hierarchical presentations, and the adoption of active learning technologies and tactics.
