Pattern and process are central concepts to understanding the evolution of behavioral traits for comparative psychologists. Origami is an art form which involves application of pattern and process to produce a wide array of objects using paper. Because of origami’s parallels with evolution, both of morphology and behavior, it can serve as a concrete and accessible analogy for students of comparative psychology. Origami’s processes can be reversed by unfolding the paper, thereby revealing patterns common across designs. Likewise, by studying pattern and process in evolution, scientists unfold nature’s origami. Application to comparative psychology and pedagogy are discussed.
