This article describes the three domain molecular tree of life. Basically this article is a reference for teachers that also explain how taxonomy has changed over time starting with Linnaeus and moving up to Woese. The authors provide an explanation that with sequencing of genes this new understanding has moved from 3 Kingdoms to 3 Domains. A chart also explains the biochemical differences in these domains. The authors believe it is imperative to explain who changes such as this are fundamental to preparing students for college biology and scientific literacy as well.

I believe it is very important for biology educators to keep their students abreast of current taxonomic models. However, with all of our obligations, it is hard for us to do a proper literature search to compare and contrast the current debate in taxonomy. Current Taxonomy in Classroom Instruction provides a clear review for those that are unfamiliar with Woese's 3 domain system of classification. It summarizes the development of the current taxonomic model by reviewing the model first proposed by Linneaus and each subsequent model. The authors offer suggestions of terms that biology teachers should use with their students to aid them in understanding evolutionary relationships among the different kingdoms. The authors explain the differences between the models concisely by outlining the criteria used to develop each model. While focusing mostly on the differences between bacteria and archeabacteria, the authors compare and contrast the major biochemical differences between the d
