The Tree, the Spiral and the Web of Life: A Visual Exploration of Biological Evolution for Public Murals


The authors created the Spiral of Life as a new, accessible symbol for the evolution of life. This novel visual interpretation of evolution challenges traditional tenets of the field in light of emerging new themes in research. The Spiral brings recent principles to the general public and also provides scientists with a new visual concept to support further discussion. The Spiral emerged from the combination of the analysis of the latest scientific research with an artistic process to create new images and icons. A resulting complementary series of artworks was installed in five cultural institutions and museums in Pittsburgh, PA.
