This Glossary is intended for both teachers and their students who are learning about evolutionary trees. To improve K-14 teachers’ and students’ as well as non-biology major undergraduate students’ understanding of trees, the Model of the Use of Evolutionary Trees (MUET) was developed based on professional biologists’ use of evolutionary trees in their scientific publications in 2012-2013. Definitions of terminology in this Glossary are referenced to published literature listed at the end of this Glossary. In addition to the Glossary and the MUET in html format, below as an additional link to a file giving you the Glossary in MSWord format so that you can easily modify it. Details of its development can be found in the Purdue International Biology Education Research Group (PIBERG) ePubs Publications collection.
