The Tree Room
Over 150 years ago, Darwin chose the tree of life as a metaphor for one of the most powerful ideas in biology: the relatedness of all living things. The power of that idea can be seen today in the ubiquity of evolutionary trees (also called phylogenetic trees) in all biological disciplines, from studies of newly discovered species to cutting-edge cancer research. Correspondingly, evolutionary trees have made their way into textbooks, museum exhibits, and the media. To understand modern biology, we all need to understand how evolutionary trees can be read and used.
The Tree Room provides a wide variety of tools for teaching and learning about evolutionary trees in both classrooms and informal science education settings. You can explore the following sections:
