Systematics: Classifying Organisms

We need a way of organizing the enormous diversity of organisms. That’s the role of the field of systematics.
Biologists working in this field attempt to identify and organize species systematically, in a way that reflects their evolutionary relationships.
In this Lesson, we'll see the tool and techniques used to build the tree of life.
